87 Octane. No ethanol. Whatever is cheapest (which means waiting until I'm out of the county. For whatever reason gas costs more here. It all comes out of the same pipeline.

Cheers.

 

I've been using Costco for awhile now b/c it's cheap, but my mileage isn't that great when I use it. I get the best MPG when using Mobile or 76. I get mixed reviews with Shell. I think it depends on which Shell station I pull in to.

 

The cheapest stuff around me by a couple of cents is always the gas stations on base so that's what I use. If I am on the road or far away from my house then I'll get whatever. The only station I refuse to fill up at is AM/PM because it pisses me off to no end that they don't accept credit, only debit or cash. So I boycott them.

 

I've been staying away from anything that posts "Up to 10% ethanol".

thats the only gas that touches my engine

 

I use Chevron because they have the best fountain sodas.

 

Haha, and I think that is about as scientifc as anyone's reasoning can really get, cuz when it comes down to it everything makes my Fit go zoom!

 

Whoever is the closest when my gas light comes on. I used to be more anal about it but in reality it doesn't make much of a difference. Even if the place closest by is $.10 more per gallon, with the Fit's tank that's not even $1 more to top it off. I'm not gonna stress out about finding the cheapest gas just to save a dollar. Generally I fill up with Mobil since it's the most popular around here and I pass one everyday to go to work.

 

And Sheetz has great coffee...

The 'avoid the ethanol' business notwithstanding, each oil company does not have its own refinery. I'm guessing there ain't much difference.

i either fill up at 76, shell, mobil, or chevron. any other gas stations i don't bother to stop at.

 

we're stuck with ethanol here in hawaii...

 

Nothing but Cheveron although its a bit expensive, but getting 38-39 mpg (hand calculated). Use to put in AM/PM (Arco), Diamond Shamrock, and Valero which I average with 34-35 mpg.
