Cool, but I dont shop at QFC ever, but do have thier card. Still good for 10 cents off if I pull up to a shell?

 

I don't shop there either but my SO does. So I just punch in her phone number into the pump keypad.

You can prob punch in the phone number of your aunt or neighbor and it'll prob work. Try it


Min maxing just for 10 cents a gallon, haha.

 

Worth a shot! Thanks for the info.

 

I always go for Costco cause its usually a good 10-15 cents cheaper than anywhere else, but if not there then chevron or shell. Anyone dyno using Costco gas? Curious of the effects vs. a chevron/shell gas (if there are any).

 

I almost exclusively use Costco gas and have never had any fuel issues. Curious too if there really is any difference between Costco and Chevron/Shell....

 

Costco gas

 

Pretty sure that Costco, like Safeway, is whoever is selling cheapest at the time. So, theoretically it could be Chevon or Shell gas.

Note that Arco is not on that list.

I assumed Arco was just cheaper pricewise since they didn't have to deal with credit card interchange fees (until recently in some regions they didn't accept cc). Don't know really how they stack up in terms of additive quality.

I don't know what Cosco uses for their gas but their "Kirkland" brand is usually relabeled from a known higher quality brand. For example their Kirkland line of Vodka is really Grey Goose. I'm sure they are using a brand from a reputable retailer.

 

From what I read they all use the same gas depot but individually add their own additives and detergents.

 

Costco for all my cars.
