Whats the quality of Costco gas?

Had to buy a few large items from Costco the other week, so I finally sold my soul and got a card. Was thinking about filling up at their gas bar, but not to sure, sometimes when I see something for too cheap makes me wonder why. I drive a Mercedes so I only put in premium 91 or 94 octane, but I was wondering whats the quality of Costco's gas, is it on par with Shell, or is it more like the no name pumps Tru value and the like?

I get the best mileage with Costco gas but I am not willing to drive to Warden/Ellesmere and wait half an hour or more. I waste as much as I save!

What RFD can do for you?

If you drive dangerously I hope you get caught and lose your license/car/dignity! :twisted: :twisted:

As a past MB and BMW owner, I ways got Shell premium gas as I knew there was no ethanol in it. The only 91 octane that had no ethanol. There was a clear mileage advantage as well as a performance advantage. The car ran way better using Shell than any other gas (Sunoco was OK too).
So, gas at Costco? Costco gas is gas from whatever refinery sells to them cheaest. Same as CT/Superstore or any other independant gas stations.

Frankly, I would love to fill up with Costco but I'm not willing to line up with 10 cars in front of me!

I remember reading something about this previously. I can't remember if it was on RFD or another forum I'm a member of. Anyways, the answer was Costco gas comes from Shell or Esso depending on pricing.

I've had no issue with the quality of gas at Costco.

When the wait wasn't ridiculous,I was getting excellent mileage.
Its cheap because Costco isn't adding the extra 7c+ every other station adds to their pocket at our expense. Drive 30-45 min from the city and stations are selling (and still profiting) at the same price as Costco.

I read that other RFD forum; I remember the email from Costco to the RFD member said the gas comes from PetroCan.

I tried their gas one time when there wasn't a line. I filled up and when I idled it would start to stall and then jump back to a higher rpm. I knew it was the gas. The gas bar was maybe 2 or 3 weeks old at most so it could have been the tank contaminents.

Well, I reset the PCM and the problem was gone. My thoughts is that the gas wasn't up to par with the Shell/Petro gas I was using, so the PCM was used to that setting, got some costco gas in and ran like crap.


Well, these are just my thoughts, dont flame, it may be different now.

Well, I know the Petro is using Sunoco, now that Sunoco have shutdown their corp locations. I've been using mostly Shell, as have been told about the Ethanol. So I'm just wondering about Costco, is it Shell, is it Sunoco, Esso, or is it like the no name gas bars we see on some corners.

Really don't want to damage my car jus to save a few cents/litre.

according to my car fuel economy calculator on my Altima.

With the same driving i tested it out...

I get the best economy from Petro at 9.1 L /100km
Shell/Esso/Costco come in roughly at 9.4/9.5 L /100 KM
