And why? Do you think it matter what brand you use?

I use Chevron, I here the Techron is a good cleaner and less combustion chamber deposits.

I've been using Amoco/BP here in Iowa, cause its the only place in town where I can get 92 with no ethanol in it. I've noticed with 91 (EtOH or not) I'll get some knockin on WOT, especially on hotter days.

That's like asking what brand milk do you use. I believe most, if not all, gasolines come from one supply and are distributed from one location to different stations.

I have a frend that is a truck tank inspector for a big transport co. and he tell's me to buy only texaco,amoco, and shell's gas. thay make all the gas and when thay store gas in those big tanks all the junk go's to the bottom. thay pull the top off to sell at there stores and the next go's to there good customers for there stores and the mom and pop place's get next and the rest get's made in to diesel. or atleast that's the way i herd it.

Chevron has their own production...Arco is junk..that's why it is cheaper...out here at least
Vette- Chevron
Isuzu- anything..even Pemex.
Toyota #1 & 2-anything
Lawnmower-anything

Exxon/Mobil for the 2% discount from Amex.

That may be true, but I belive that the differents are the additives.
I've heard that the techron cleans the injector better then other additive. All though we do not have injectors, I would think that it would also be good for the resons stated in my first post.

The gasoline tank farm in Mission Valley is supplied by one big pipe from Los Angeles. You see trucks from every brand arriving/leaving. I believe the gas is co-mingled.

That would be interesting...I'll check it out...

I agree Nothing but that fuel will do for my Stroker. I broke it in on Chevron and now it pings on anything else. Period.

SanDiegoPaul

I heartily disagree!

There is a distinct performance hit when I use cheapo gas such as Arco or Thrifty, in ANY of my cars.

Found this in a simple search..California of course
-------------------------------------------------------------
It is not certain that California Phase 2 RFG will cause any incremental elastomer failures. However, in light of the fact that Chevron's testing indicated a potential problem, we believe that our customers deserve to be informed, enabling them to make their own decisions based on all the information available.

Chevron recommends that owners of older or high-mileage vehicles consult an auto repair technician about possible repair or replacement of fuel system parts. Owners should monitor their fuel systems for leaks, repairing any leaks immediately. Vehicles never should be operated with a fuel leak.

Three years ago,I replaced my fuel pump,and fuel hoses....glad I did...must check/change tank hoses now...

I used to use the cheapest 91 I could find but now I try to use 76 or Chevron.I do believe it makes a difference.

Corey_68

Shell gas ONLY

Carl Granquist

Now only Chevron, but I used to use 76. I don't notice a performance difference though.

I shot video last year at a Major refinery here in Texas and every imaginable brand was having their tanker trucks filled out of the same tanks. Hmmm
By the way I use all brands of regular unleaded none seem to make a difference one way or the other. Just my .02 cents worth.

Shell 94 Octane. We have it in Michigan & it makes a positive difference

Yellow73SB

sunoco race fuel other than that bp amaco(sp?) my dad has been using amaco for 20 eyar and he has 250,000 miles on his work suburban and its still going.

norvalwilhelm

Nothing but Sunoco 94 because it is the highest octane I can readily get. Under 12 pounds of boost my compression ratio is 14.5 to 1
