I used to pour 87 octane in my GT and even tried Petro-Canada's 94 octane for a couple of tanks but none compared to the new V-Power gas from Shell(91 octane).

My completely stock GT runs silky smooth like it never has before

 

im thinkin about switching to Shell gasoline, I heard good things....

 

I have beem using Shell 93 Octane since I picked up the car in Feb of this year. No issues with it other than the price, but they are a darn site better than BP which runs about 20 cents more per gallon than the Shell 93.

 

My car runs best on the Chevron 93 or the Shell 93. I've tried 2 different BP stations here, both make my car ping where the Chevron or Shell doesn't.

 

2006 Fords are coming with a sticker on them that says "Ford recomends BP gasoline"

 

I put... whatever the Base Exchange has in my car... I just make sure it is Premium...

 

I've read that as well. It's supposed to be stickered on the gas cap, correct?Wonder if Ford will start running the line . . "Well your car would have been covered if you used BP."

I don't think it will go to that extreme, but nontheless this is marketing taken a little too far.

 

My car runs best on Shell too. Chevron isn't offered here in Indiana but I have ran it too while traveling and it seems to increase the fuel mileage a little bit and runs great! BP gas here, is the old Amoco which has the ultra clean Ultimate gas. I have tried it and it runs very smooth but I get the best performance with Chevron and Shell. All 87 octane for me, so far No CAI for me yet but I plan on getting it soon and a tune. We also can get Sunoco 94 octane here. Haven't tried it though.

 

Maybe those fish on the Shell V Power commercial really know something.

 

If you are going to use 91 octane then I recommend getting a programmer from Superchips or Predator so that you can benefit from the fuel. The computer which is mapped to use 87 octane will lean out your A/F mixture trying to compensate for all the unburned fuel going out the exhaust.

 

Shell 93 octane works very well with my C&L intake and Predator tune. BP premium use resulted in sporadic detonation on two separate fillups. Citgo seems OK too. Premium sits at $2.45 here in Westminster, MD...

I've narrowed my best engine experiences to when I am using Shell 91 (no 93 in CA). I ping incessently with Mobil or Arco. Chevron has been okay, but I'm sticking with Shell.

 

The computer is mapped to premium fuel, it relies on the knock sensors to adjust timing to allow it to run on 87. Check out august 2005 5.o mustangs and ford it refers to this in an article on supercharging th 2005.
You won't do any harm runnning premium in a stock GT.
and if you choose to run 87 the knock sensors will accomodate that.

 

I use Sunoco or Shell. They do not use any oil from the middle-east.

The Dept of Energy tracks oil imports by company each month. Here's the link, The latest monthly Company Level Imports files..

 

a triple post, wow don't see that very often

 

EXCELLENT Information !!!!!!!!!!!!!!!!!!!!!!!!!!!! Thanks

I'll be a Shell customer now.

 

It all comes from the same tap, only difference is AMACO 93 oct which they clean the pipes out for seperatly. The additives at the truck or tank are the only variables. In my area, its the Marathon refinery taps. Doc

 

I believe Shell has the best quality gas around. But they are also the most expensive.

 

They can recommend it all they want, I won't run it in my car as long as there's a Shell or Chevron close by :P.

 

BP/Amoco Always made my last 2 cars exhaust smell like rotten eggs. Anywhere else it was fine. Plus a clogged fuel filter after 10,000 miles on premium also discouraged me from ever using them again.
