V powa!!

 

I have been using Costco gas in my old maxima and my New 2011 G37s. I thought i am putting 93 octane and it is good enough.

Costco is not listed in the Top Tier Gas in the link provided above. Should i change to Shell?

 

I have always used BP (Amoco fuels) in all my G's... don't know why but a long time ago I was under the impression that Amoco was one of the better premium gasoline options out there.

Plus, w/ a BP credit card, (at most stations) you get a 5 cent per gallon discount on their gas and cash back

 

I always use Sunoco Ultra93, I'm very happy with it. I really don't have a Shell near me otherwise I would consider a change.

 

i used husky 94 octane for a while (with 10% ethanol) and my milage was crap, i used v power now

 

Costco all the way :P It's best on your wallet....

 

Not really, not if you do the math; the long term expenditures that is...

 

76

 

V POWA!!!!

But seriously, I've never put anything in my tank besides Shell, except maybe a gallon or two when I can't get to a Shell station. From my house, I have to drive past at least 4 different gas stations to get to the Shell station, it's kind of funny; and my friends always ask why it takes me at least 20 minutes to drive to fill up.

 

Valero!!

 

Shell 90% of the time, sometimes Conoco or Exxon. I have not really noticed a difference between these three.

 

I get the best gas mileage with 76 and Shell. The worst with Chevron; I run Chevron though. I have this weird ***...OCD type affiliation with Chevron

lol.

 

My Maxima has been filled with chevron since day one. In the G I alternate between Chevron and Shell. Get both the benefit of techron and Nitrogen.

 

Did anybody shifted from Costco to Shell? Just looking to see if it made any difference? The difference between Costco and Shell in my area for 93 octane is 15 cents.

 

Such as...? Mind elaborate a little bit more?
