I've seen about four posts on various social media platforms from fairly reliable people showing Denver Costco locations that are selling premium at the regular price because the regular pumps have been turned off.
Normally I'd downplay this sort of thing as garbage, but I'm inclined to believe this one.
Confirmed at the Costco off Quincy and Wads in Littleton as of an hour ago. $1.99 gallon for premium and regular gas had a sign that said only premium was available.
That’s my thoughts. They want to remove the bad gas from service and keep the premium and discount the price a bit for the inconvenience to its customers.
If you pumped premium, you’re good. I pumped premium today from a Costco in the Springs.
I worked at a gas station in college and there are typically three tanks: Regular, Premium, Diesel. Mid-grade, when offered, is a mix of Regular and Premium.
The news article mentions that only regular grade was contaminated. That’s a separate tank and Costco has no mid-grade, so there is no mixing.
Be sure to check Gas Buddy or a similar app to find the real gas prices around town. Costco isn’t always the cheapest and it varies quite a bit even among Costcos as you’ve seen. In south Denver I get cheaper gas at an independent on Evans, weirdly, thx to that app.
Can vouch for this. There was a sign taped over the regular pump at the Havana Costco in east Denver. Got premium for the price of regular. Good on Costco.
I got a full tank of gas at Costco river point around 6pm yesterday. I drove my car 25 minutes home and then 20 minutes to work each way. I think I’m in the clear(?) but I’m also supposed to drive up to Copper mountain tomorrow
I got gas at the Riverpoint Costco Wednesday evening and didn’t notice any issues driving my car back home. Someone else on a different Reddit post said they called that Costco, and was told the bad gas didn’t get delivered until after close Wednesday for that station
I called Costco a little bit ago to confirm, and they said that anyone that filled up at Riverpoint Wednesday is unaffected. The issue was between 6am and 8am Thursday, at least for that location
I saw this article on my phone and was trying to remember when I got gas. My Volt runs mostly electric so I haven't run the gas that I got. Luckily I got gas a few days before this happened.
This is terrible! Also the risk of this happening is why I try to keep every receipt from my gas fill ups (except when it tells me to see the cashier 😅)
Credit cards website, lol but great point. More documentation is better than less though. That statement wouldnt show what grade of gasoline I used. But then again I dont remember if the receipt shows that...
Once the fuel system is drained and has good gas running through it again it will be fine 9/10 times, it could potentially damage the fuel pump or injectors but that is quite rare. This is quite common with rental Land Cruisers, as they are traditionally diesels outside of the US. Thank goodness it wasn't the other way around.
Diesel in a gasoline engine just doesn't combust and the car won't run
Gasoline in a Diesel engine will prematurely detonate and cause catastrophic damage. That's why diesel fill nozzles are smaller, so you can't fit a gasoline one in.
Update: I pulled up to work today and we have over a dozen getting towed in
I gased up at the River Point Costco on Thu at about 6:50am... car had to get towed to my shop. I called the night manager at the River Point Costco that evening and she confirmed the issue, took my name & number and said someone will call me on Friday. Today (Friday) the shop called: $1,600 bill and Costco called me at 8:20am. Person I spoke with took down info for their claims process & said to keep all receipts. My car should be ready to be picked up Monday after work.
I'm seeing it elsewhere on Reddit but it sounds like all the stores are aware of it and shutting down those pumps. Charging the same price for premium instead
From the news reporting, it looks like Sheridan Costco was tested and confirmed diesel in the regular tank. I assume Costco shut down the entire station as a precaution and to make it safer to do what is needed to clean out the contaminated tank.
If you're getting gas now the stations that are affected should be aware of it and have stopped pumping. I got gas earlier at my local (affected) King Soopers and they had the regular and midgrade blocked off, only premium and diesel available. Seems to be the regular and midgrade got contaminated with diesel at the distribution level somehow.
Its likely only the regular was effected then. Mid grade is mixed at the pump by taking some from each of the regular and the premium tanks underground.
Ah okay, thank you! Yeah I wasn't sure if it would be blatantly obvious or if the symptoms were subtle. I got gas in that danger window and I was a bit worried, but I'm probably good then!

Yes. If baseline before your car was running fine you would absolutely notice a problem. Depending on the gas to diesel ratio it could run with no problems or it could make the car inoperable or run poorly. Diesel doesn't combust in a gas engine but it won't ruin it. (Usually)
It seems like everyone (stations) got a tanker full of diesel straight to the regular gas tank so likely farther down the ladder.
If you do get a bit of diesel you can top up with gas and each time you hit 3/4 fill up again to further dilute it until it runs better but that advice is usually for larger tanks and a gallon of diesel. (Accidental fill ups and you catch it)
To fix it you gotta drain the tank and fuel system so it's labor and sometimes it can kill the fuel pump and filters. Usually this is covered by whoever did the messing up so the refinery?
What seems to be the case is that any seller of Sinclair (Top TIer) fuel may have received contaminated fuel…there’s no way they could definitively say when it was/will
Be resolved if they can’t even be sure where it was and wasn’t sold….hopefully it has not affected too many unknowing people. For myself at least, I think I’ll just stick to other options for a bit.
I got gas at the Sheridan Costco like 2 days ago and my vehicle started running super rough all of a sudden. It’s not throwing any codes so I took apart and cleaned the throttle body and swapped the MAF sensor today and it’s still running funny to the point I don’t want to drive it.
Actually, I just checked my card and I fueled up on the 4th. Either it’s a crazy coincidence or they’re downplaying when the mixed fuel actually went out bc according to that news reel it was from the 7th and 8th.
I work for a Hyundai dealership and can confirm today we got a car from a King Soopers in Castle Rock and a car from a Costco near Park Meadows, both of which ended up being filled with diesel. Customer of the first car, from King Soopers, found some documents of their own confirming that at the very least King Soopers is working with their insurance agents regarding this but it'll be hard to say how receptive they are, other customer said Costco is working with them as well. It seems like it only affects regular (85 grade) fuel, not premium (91) so far. 87 won't be safe though since that's made by mixing the two (in most cases I've seen)
I really wish we had a list of Costcos impacted. My partner and I both got gas at seperate costcos last night during the window listed and we have to be somewhere in the morning... Is there a way to check if there is contaminated fuel in the car?
Oh that is great to know. I drove from longmont to city park in Denver. And my partner drove from Aurora to city park. So it sounds like we lucked out. Thank you for the education! I tried researching and found symptoms to look for but was struggling to figure how quickly the seizing would happen.
Wow I filled up at Costco in Littleton yesterday but bought a new car last week that needs premium gas. To think I was bitter because I had to pay a little extra for the first time. Sounds like I might be ok.
I swear this has happened with Costco before. I used to religiously get gas there, until my car broke down. They said it was because of bad fuel. I had only filled with Costco for the past few months leading up to that.
Called the Lone Tree/Park Meadows Costco and their tanker offloaded Wednesday evening. Car definitely feels sluggish but drove 25 miles around Denver yesterday. Ended up dropping off car at shop and waiting on diagnostics
That’s why I always print the receipt- if they make a mistake, it’s easier to prove when it comes to repairs. How much damage does diesel fuel actually do to an engine that’s meant to take regular gas? I assume if you drive it long enough, you’d end up needing a new engine.
I have a 2025 Land Cruiser. Filled up at River Point Costco at 7:45am on Thursday. After work car was running terribly (actually would not let me into gear it was so bad) and had it towed to dealer. Dealer confirmed this morning contaminated fuel.
The 6am cutoff time the media reporting is NOT correct.
Well, it sounds like Premium is still fine at these locations. Which is good cause that's all I get really anyway. Not sure if it's bad to put regular in a turbocharged engine, but I tend to follow what my manual recommends.
Wow. I got gas just before this was posted, at one of the affected locations from the 9news article. The pumps all had handwritten signs “Out of 85 and 87”. 91 was being sold for the 85 price. Hopefully that means they flushed the contaminated fuel; I assume so.
Unfortunately I just broke my EV because I put the wrong grade of electricity in it. Am I not just supposed to hook jumper cables up to my 3phase panel? Is there a plug or something?
Ugh. Filled up there this morning. I’ve been driving fine all day, haven’t noticed any issues. Time to research “symptoms” of filling with diesel to understand if I’m about to break down tomorrow on my way to work. 😫
I filled up at Arvada Costco at ~2 and have driven around ~30 miles, not sure if that would have been enough to notice issues but...hopefully we're safe?
I filled up premium (91 octane) just last night at Costco in Arvada and have computer chip tuned for performance and efficiency and have had zero issues
Damn, I am not glad I forgot to fill up at Costco Cottonwood Plaza 90 minutes ago. I was passed driving away with an empty tank but in hindsight I guess I lucked out
It’s not possible for gas/diesel to get mixed up in the tanks at a Costco station. If it ever did happen multiple sensors are constantly monitoring the tanks and alarms would be blaring. The attendant would have to shut down the station to investigate.
So that would explain if Costco shut down the regular pumps.
I just filled up my tank this afternoon and the gas station had the 85 and 87 octane pumps marked as out of order and 91 was sold at the 85 price. This was at about 3:30pm at the King Soopers in Erie off of HWY 7
I'm not seeing anything besides 9news listing Denver Metro so far, but I put the warning out to friends in Southern Colorado just in case since this thread claims Springs too. Has anyone tracked anything down I've missed?
Fingers crossed and thanks for the feedback. I feel terrible for everyone that got gas and might not have kept the receipt and now their car isn’t working. I know i almost never get a receipt.
What evidence do you have of anyone downplaying the issue? From what the mod posted and other people’s cost hand experiences it would appear everyone is taking this seriously
Anyone know if Costco in Colorado Springs near Barnes was affected? I filled gas around 4PM today. I made it home which was less than 10 minutes away and now my car won’t turn on. I filled with premium but it’s super odd that it just stopped working out of nowhere.
Maybe apropos of nothing, but.... my wife and I are truck drivers (Northglenn is our home base). Yesterday we tried to fuel at the TA in Greenland, New Hampshire, and the entire fuel island was completely shut down. In 6 years of driving with nearly a million miles on the road, it's the first time I've ever seen anything like it. There were multiple fuel tanks on site that were positioned in such a way that it sure made it look an issue of contaminated fuel.
Notes: 1. TA is owned by BP/British Petroleum. 2. Greenland, NH is not the same Greenland that has been in the news recently as the next-coveted U.S. annexation target. 😁😄😂
I was at a Costco around 4pm Wednesday filling up. There was a tanker there at the time offloading. I’ve driven twice now both short distances and no negative issues, am I in the clear?
Lol. "A professional fuel hauler?" Its more like any idiot with a CDL and haz mat endorsement that can pass a drug test with fake piss. They pull up to the refinery and load a truck and take it to the station they are told to take it to. The refinery the hauling company and the gas stations have zero connection to eachother outside of the business transactions of ordering and delivering.

Filled up and am wondering if I shouldn’t have….
https://imgur.com/a/LVSaxZA
If they shut the normal down because of the issue but left the premium open I’d venture that the premium is fine.
That’s my thoughts. They want to remove the bad gas from service and keep the premium and discount the price a bit for the inconvenience to its customers.
Guess I'll be getting premium this weekend since I need gas!!
If you pumped premium, you’re good. I pumped premium today from a Costco in the Springs.

The news article mentions that only regular grade was contaminated. That’s a separate tank and Costco has no mid-grade, so there is no mixing.
I have literally mixed mid grade at a rack into my Heil fuel trailer by combining regular and premium. Accurate statement.
Literally?
that's my Costco! almost shame I have epilepsy and don't drive
Same, I filled up at the Costco in Superior today and they were doing the same thing. Although it was more expensive at $2.15/gallon
Be sure to check Gas Buddy or a similar app to find the real gas prices around town. Costco isn’t always the cheapest and it varies quite a bit even among Costcos as you’ve seen. In south Denver I get cheaper gas at an independent on Evans, weirdly, thx to that app.
Same with the Costco in Parker yesterday
The castle rock Facebook pages have been going since 8am this morning.
A Toyota dealer had a half dozen cars show up in the span of a few hours from it according to one person who got diesel.
Can also confirm! Filled up at 7 pm tonight at Costco in Superior. No regular, only premium (being offered at regular price of $2.15/gallon).
It’s legit, I have two neighbors affected and know of many others in my area.
It’s real
Can vouch for this. There was a sign taped over the regular pump at the Havana Costco in east Denver. Got premium for the price of regular. Good on Costco.
Confirmed in Westminster yesterday
The King Soopers fuel station on Parker & 225 did this too! I got premium today for $2 a gallon
Yep, just experienced this at the Costco on Airport Way.
My husband is an auto shop manager. He was bombarded with victims of the King Soopers gas today. It’s bad.
State agency investigating after dozens of Colorado gas stations received contaminated fuel Anyone who got gas between around 2 p.m. Wednesday and 6 a.m. Thursday and thinks they may have been affected can file a complaint with the agency. https://www.9news.com/mobile/article/news/local/colorado-news/state-agency-investigating-colorado-gas-stations-contaminated-fuel/73-5a935c3a-50bf-40e4-9ede-3167d7237f92
Huge! Thanks for this!
Here’s the complaint file link if you were affected https://ops.colorado.gov/sites/ops/files/2019-11/consumer_complaint_form.pdf
No problemo. It literally popped up on my notifications while I was reading you post

Hopefully this can get pinned at the top since it’s a news source outlet confirming the issue.
This is terrible! Also the risk of this happening is why I try to keep every receipt from my gas fill ups (except when it tells me to see the cashier 😅)
Haha, I do the same thing! My husband says it's a waste but....
all the relevant information is on your bank's website though...
Credit cards website, lol but great point. More documentation is better than less though. That statement wouldnt show what grade of gasoline I used. But then again I dont remember if the receipt shows that...
Not if you pay cash.
Great. I just filled up at Lone Tree last night.
Get ready to suc
r/redditsniper
My shop currently has 4 of these. It's fucking bad.
All 4 got gas from the River Point Costco and do not run, all 4 are gonna need at least 2 hours of labor to drain the bad fuel.
Once the car is drained, is it going to be okay or is there ever going to be permanent damage?
Once the fuel system is drained and has good gas running through it again it will be fine 9/10 times, it could potentially damage the fuel pump or injectors but that is quite rare. This is quite common with rental Land Cruisers, as they are traditionally diesels outside of the US. Thank goodness it wasn't the other way around.

What do you do with all the contaminated gas? Man, that sounds like a mess.
They probably send it back to the refinery, it would make a great feedstock.
The refinery also probability charges, because they can and it's cheaper then other hazardous waste disposal options.
Sooooo free diesel? Can I bring my truck over?
I doubt you're gonna want to put that shit in your truck. It's gotta be at least 10-20% gasoline.
I'm seeing it elsewhere on Reddit but it sounds like all the stores are aware of it and shutting down those pumps. Charging the same price for premium instead
This was my experience this afternoon, charged regular price for premium
Got gas at Costco this morning; can confirm.
So as long as we got Costco gas after 6 am we should be ok?
It’s legit.

Yeah I'm literally about to go get groceries and gas from costco. Where is this coming from?
Sheridan Costco gas station was closed at about 3:30 today. I wonder if this is why.
I'm filling up at QuikTrip instead just in case.
From the news reporting, it looks like Sheridan Costco was tested and confirmed diesel in the regular tank. I assume Costco shut down the entire station as a precaution and to make it safer to do what is needed to clean out the contaminated tank.
I follow Steve Seager and he just posted about it.
This is going to be a massive problem for a lot of people
If you're getting gas now the stations that are affected should be aware of it and have stopped pumping. I got gas earlier at my local (affected) King Soopers and they had the regular and midgrade blocked off, only premium and diesel available.

Seems the state agency confirmed it.
How certain are we that the gas only went out from Wed-thurs? I got gas Tuesday at Costco in Westminster.
(Not a car person) Would you know if you were affected ?
Yes. Your car would be very angry.
Thank you
What kind of symptoms would you notice?
Misfiring, car might struggle to run, very rough idle, probably some bad sounds. Might not even run. It would be obvious.
Ah okay, thank you! Yeah I wasn't sure if it would be blatantly obvious or if the symptoms were subtle. I got gas in that danger window and I was a bit worried, but I'm probably good then!

I got contaminated gas and my car broke down after a mile and a half. You’d know.
I almost filled up tonight... so glad my procrastination paid off
Right there with ya.
Ah. Glad to see this after I just filled my car up with Costco gas
Ditto…ugh.
Here’s the list from 9news…KS, Costco, Murphy’s express and others
967 Candelas Pkwy., Arvada 25701 E Smoky Hill Rd., Aurora 15109 E Colfax Ave., Aurora 17000 E Iliff Ave., Aurora 3050 S Peoria St., Aurora 19001 E Quincy Ave., Aurora 1045 S 1St St., Bennett 3600 Table Mesa Dr., Boulder 1650 30Th St., Boulder 12167 Sheridan Blvd., Broomfield 2355 W 136Th Ave., Broomfield 7284 Lagae Rd., Castle Pines 750 N Ridge Rd., Castle Rock 5125 W Florida Ave., Denver 1891 State Highway 7, Erie 6000 S Holly St., Greenwood Village 11747 W Ken Caryl Ave., Littleton 9820 W Belleview Ave., Littleton 1611 Pace St., Longmont 12959 S Parker Rd., Parker 17761 Cottonwood Dr., Parker 13700 Colorado Blvd., Thornton
This list is ONLY King Soopers. Costco has not released a list.
What seems to be the case is that any seller of Sinclair (Top TIer) fuel may have received contaminated fuel…there’s no way they could definitively say when it was/will Be resolved if they can’t even be sure where it was and wasn’t sold….hopefully it has not affected too many unknowing people. For myself at least, I think I’ll just stick to other options for a bit.
13700 Colorado in Thornton was removed.
I got gas at the Sheridan Costco like 2 days ago and my vehicle started running super rough all of a sudden. It’s not throwing any codes so I took apart and cleaned the throttle body and swapped the MAF sensor today and it’s still running funny to the point I don’t want to drive it.

It is quite a coincidence. But I don't think they could have served bad gas for 3 days before being noticed.
Ok what should the rest of us do that don’t know how to do that? Should I have it towed somewhere and drained? Is that a thing? 🤪
Definitely don’t drive it
Plannin on getting it towed and drained
I work for a Hyundai dealership and can confirm today we got a car from a King Soopers in Castle Rock and a car from a Costco near Park Meadows, both of which ended up being filled with diesel. Customer of the first car, from King Soopers, found some documents of their own confirming that at the very least King Soopers is working with their insurance agents regarding this but it'll be hard to say how receptive they are, other customer said Costco is working with them as well. It seems like it only affects regular (85 grade) fuel, not premium (91) so far. 87 won't be safe though since that's made by mixing the two (in most cases I've seen)
Any repair cost other than labor? Like was anything permanently damaged?
Usually just cleaning and flushing.
I really wish we had a list of Costcos impacted. My partner and I both got gas at seperate costcos last night during the window listed and we have to be somewhere in the morning... Is there a way to check if there is contaminated fuel in the car?
How far did you drive after filling up? Most cars you’d be lucky to drive for longer than 5 minutes before the engine seizes and becomes inoperable
Oh that is great to know. I drove from longmont to city park in Denver. And my partner drove from Aurora to city park. So it sounds like we lucked out. Thank you for the education! I tried researching and found symptoms to look for but was struggling to figure how quickly the seizing would happen.
Wow I filled up at Costco in Littleton yesterday but bought a new car last week that needs premium gas. To think I was bitter because I had to pay a little extra for the first time. Sounds like I might be ok.
So I just got regular gas from the king supers on Cheyenne meadows today. Can I expect my car to just breakdown at some point? Lol
Is there any ways to verify what type of fuel I got?
Most mechanics can tell the difference by smell.
Dang I went to a kings this morning at like 10am and they were selling premium for regular prices, this gotta be why.
I swear this has happened with Costco before. I used to religiously get gas there, until my car broke down. They said it was because of bad fuel. I had only filled with Costco for the past few months leading up to that.
The news is reporting this likely affects those who gassed up on Jan 7th and 8th
i gassed up at one of these sites on the 3rd and took it out for 10 miles and everything seemed fine.
Has anyone had issues after filling up at the Lone Tree Costco? Filled about half a tank last night…
Called the Lone Tree/Park Meadows Costco and their tanker offloaded Wednesday evening. Car definitely feels sluggish but drove 25 miles around Denver yesterday. Ended up dropping off car at shop and waiting on diagnostics
That’s why I always print the receipt- if they make a mistake, it’s easier to prove when it comes to repairs. How much damage does diesel fuel actually do to an engine that’s meant to take regular gas? I assume if you drive it long enough, you’d end up needing a new engine.
It reduces octane.
I have a 2025 Land Cruiser. Filled up at River Point Costco at 7:45am on Thursday. After work car was running terribly (actually would not let me into gear it was so bad) and had it towed to dealer. Dealer confirmed this morning contaminated fuel.
The 6am cutoff time the media reporting is NOT correct.
It says the tanks were filled between 2pm Wednesday and 6am Thursday. Not if you got gas between those times.
This has solidified my loyalty to QuikTrip 🫡

Did you get regular or premium?
Explains why Costco only had Premium available this evening
I have never been so thankful that I have to put premium gas in my car.
Has premium gas not been affected?
I read it was just 85
Oof, our Erie King Soopers was impacted. Bullet dodged.
It was removed from the list, Erie locations were not impacted
Hadn’t seen that it was removed. Thx.
Well, it sounds like Premium is still fine at these locations. Which is good cause that's all I get really anyway. Not sure if it's bad to put regular in a turbocharged engine, but I tend to follow what my manual recommends.
If you have a knock sensor it is unlikely to harm your engine. You may see a bit less performance under full throttle.
Wow. I got gas just before this was posted, at one of the affected locations from the 9news article. The pumps all had handwritten signs “Out of 85 and 87”. 91 was being sold for the 85 price. Hopefully that means they flushed the contaminated fuel; I assume so.
Sounds like a cross drop
My Mustang Mach E is driving great! 😂
Now listen here buddy
Unfortunately I just broke my EV because I put the wrong grade of electricity in it. Am I not just supposed to hook jumper cables up to my 3phase panel? Is there a plug or something?
Improperly charging your
EVServitor is HERESY! You did not perform the proper protection rituals and risk the wrath of the Omnissiah.Lol is it though?
Unbridled mode all day long!
My Leaf is doing fine!
For what it's worth, when I drove by the Arvada COSTCO it had no customers and two different fuel semis...
Ugh. Filled up there this morning. I’ve been driving fine all day, haven’t noticed any issues. Time to research “symptoms” of filling with diesel to understand if I’m about to break down tomorrow on my way to work. 😫
I filled up at Arvada Wed at 1:30pm and haven’t noticed anything with my vehicle
I filled up at Arvada Costco at ~2 and have driven around ~30 miles, not sure if that would have been enough to notice issues but...hopefully we're safe?
I filled up there yesterday at 10:30am so I called this morning and they said they weren’t affected by the mismatch
I filled up premium (91 octane) just last night at Costco in Arvada and have computer chip tuned for performance and efficiency and have had zero issues
Sounds like it only affected 85 and 87 so you're good!
Damn, I am not glad I forgot to fill up at Costco Cottonwood Plaza 90 minutes ago. I was passed driving away with an empty tank but in hindsight I guess I lucked out
From another post:
It’s not possible for gas/diesel to get mixed up in the tanks at a Costco station. If it ever did happen multiple sensors are constantly monitoring the tanks and alarms would be blaring. The attendant would have to shut down the station to investigate.
So that would explain if Costco shut down the regular pumps.
Someone else posted about a shortage earlier, probably explains it: https://www.reddit.com/r/Denver/s/nIvjitIn6Z
Loaf and Jug my homies for life 🙌
Well crap - I filled up at Littleton Costco (Quincy/wads) around 250 pm yesterday (1/7), but my car is running fine.
I filled from the same location between 12-1 pm yesterday. But my car is running fine as well.
I just filled up my tank this afternoon and the gas station had the 85 and 87 octane pumps marked as out of order and 91 was sold at the 85 price. This was at about 3:30pm at the King Soopers in Erie off of HWY 7
I'm not seeing anything besides 9news listing Denver Metro so far, but I put the warning out to friends in Southern Colorado just in case since this thread claims Springs too. Has anyone tracked anything down I've missed?
Does anyone know if premium fuel (91) was also contaminated? I got gas at the king soopers location on Colorado Blvd on Wednesday afternoon:(
The only information I have is it was only 85 and 87 octane that were contaminated. Premium was fine.
Fingers crossed and thanks for the feedback. I feel terrible for everyone that got gas and might not have kept the receipt and now their car isn’t working. I know i almost never get a receipt.
Thank you! I was going to fill up at Kings on my way home from work tomorrow, but I’ll go elsewhere, instead.
Curious if that’s why Costco had a sign that said they only had premium today
What evidence do you have of anyone downplaying the issue? From what the mod posted and other people’s cost hand experiences it would appear everyone is taking this seriously
A lot of conjecture currently but it's widespread
Anyone know if Costco in Colorado Springs near Barnes was affected? I filled gas around 4PM today. I made it home which was less than 10 minutes away and now my car won’t turn on. I filled with premium but it’s super odd that it just stopped working out of nowhere.
This might explain the King's at Stroh. I got 91 for $2.20 a gallon, when 87 (which I normally need) was $2.50 and pumping REALLY slowly
Maybe apropos of nothing, but.... my wife and I are truck drivers (Northglenn is our home base). Yesterday we tried to fuel at the TA in Greenland, New Hampshire, and the entire fuel island was completely shut down. In 6 years of driving with nearly a million miles on the road, it's the first time I've ever seen anything like it. There were multiple fuel tanks on site that were positioned in such a way that it sure made it look an issue of contaminated fuel.
Notes: 1. TA is owned by BP/British Petroleum. 2. Greenland, NH is not the same Greenland that has been in the news recently as the next-coveted U.S. annexation target. 😁😄😂
Anyone have issues with Westminster off 92nd Costco? Filled up 1/7 at 4:20pm but car is running fine.
Why isn't there any media on this? Any issues from Costco in GVR?
Hope not. This Costco does not have Deisel IIRC?
I was at a Costco around 4pm Wednesday filling up. There was a tanker there at the time offloading. I’ve driven twice now both short distances and no negative issues, am I in the clear?
what costco?
i inadvertently filled up at one of the affected stations thursday morning, and was fine.
they’re saying it was resolved by 6am thurs, so i’m inclined to believe it
Someone posted this about Circle K as well
Thank you! I always go to Soopers. Glad I saw this.
Costco at Riverpoint (Santa Fe and Oxford) 1.96
Does this apply to any other stores, such as Safeway? I got gas there yesterday
How would I know?
What should I do?
My Costco shut off their regular gas pumps and is offering premium gas at a discount because of this contamination.
I'll be filling up over at Buckley AFB before I get my groceries from the Commissary.
Arvada Costco - just called and they said they were not affected
Wow! I'm not going to take my Chevy to the King Soopers on 136 to test this theory though
Is the diesel fuel similarly contaminated? My SUV has a diesel engine, and I don't want to accidentally fill it with contaminated diesel.
Is 87 unleaded affected or just 85 unleaded?
Wonder if any of those affected drive Lyft/Uber ?
yet another reason to drive an electric... aint no contaminating my fuel!

They must have loaded the tankers wrong at the depot. Still, wouldn't a professional fuel hauler catch this before dumping his load into the tank?
Lol. "A professional fuel hauler?" Its more like any idiot with a CDL and haz mat endorsement that can pass a drug test with fake piss. They pull up to the refinery and load a truck and take it to the station they are told to take it to. The refinery the hauling company and the gas stations have zero connection to eachother outside of the business transactions of ordering and delivering.
I've always hated Costco gas,, so much so that I switched to a Sam's membership instead of Costco - now I feel vindicated haha
