Apparently gasoline varies from brand to brand. I put in 92 octane from SuperAmerica and the car pinged under full boost. I put in 92 from Chevron and the pings stopped. What do other Rennlist members prefer?
And why?

TIA

I prefer Chevron, but I hear Texaco is now the same company with the same gas.

I DON'T use 76 after a bad expierience I had with them.

I am not sure I have a logical reason for using Chevron, but I hear it is good to stick to one gas.

ERAU-944

i alternate between "chevron" and "cumberland farms" gas... the difference being chevron has techron... both are 93 octane, and i get no pinging whatsoever... not sure how it works for turbos

i have also heard that amoco is good, the gas is clear (the supreme is anyway)

Chevron. Every time.

Over here in The NJ area we have, Exxon, Shell, Mobile and Sunoco (to name the big ones) And I must say that Sunoco is by far the best of all, especially with thier Ultra 94 octane

My best friend growing up and in HS had a dad who was a major sales rep for Sun Oil (Sunoco). Their house was literally full of Sunoco crap. Old gas pumps, hats, Sunoco telephones, you name it. Anyway I asked him once about why his gas was so special (ok this was at least 10yrs ago).

Anyway, he told me "marketing" and that there's so much inbreeding that the inner circle of oil refinery business is like one big incestual relationship, sort of like the telecom industry, and that most of the gas is pretty much the same stuff or comes from the same refineries (or refining recipe) assuming everything else being equal (octane, etc). Sun Oil does have 94 octane though and I dont see too many others with that high an octane. Im just relaying the story is all.

UDPride,

You are very right, 90% of the gas comes through the same pipes (at least in Cali). However, each company has their own additive package. Also, I think 76 mis-handled their gas and got water in it (in my bad expierience).

The difference is in the additives. I prefer Chevron because of the additives, but the gas mileage is generally lower. Seems additives don't burn well!

I think it's Shell and Texaco who are the same now. Chevron is the old Gulf, and of course there's always ExxonMobile. <img src="graemlins/burnout.gif" border="0" alt="[burnout]" />

Nothing but Chevron 94, car loves it.

All Chevron for me. If Sunoco was available over here, I would go for that. I think it has everything to do with the Trans-Am, FIA, and Can-Am cars of Mark Donohue and Roger Penske.

In karting, I always preferred the Elf fuels because it made me think of huge horsepower '80s F1 turbo cars, French girls, and Elf's driver development program. I wasn't fond of the Trick racing fuel that was usually available because it made me think of Saturday night circle track racers.

I think that is also why if I ever had to buy a full size truck for a tow vehicle, I would probably buy a Ford, even though I keep hearing about how their quality sucks! Ford makes me think of CART, F1, World Rally, Touring Cars, Capris, Escort Cosworths, GT40s, etc. When I think GM, I think of their old policy not to support racing, NASCAR, and how ****ty their support of their Cadillac sportscar program is. Their Corvette program IMNSHO is the best thing they've got going. Some of their foreign brands (Opel and Holden) have some cool things going, but there is nothing on the international level that stands out.

I feel kind of stupid that I respond to this kind of marketing, but I can't help myself... it works! I guess that is why racing is a going professional concern.

Hmm, you must be in that OTHER Seattle. It was 92 at all Seattle Chevron stations. Usually 91 was only at Arco or other crappy stations like that.

You don't need to go to Vancouver to get good gas. Just take highway 18 east, go one exit past Seattle International Raceway, make a right, and you should be able to get as much octane as you need at the Union 76 on the right.

I always use Mobil, never expierenced anything different when I wasn't around my normal gas pump.

Techron really does make a difference. A lot of additives just seem to be hype to me, but Chevron does result in cleaner valves.

If you don't have Chevron in your area you can buy Techron as an additive. I think you put it in one tank every 3000 miles or so.

Sunoco ultra 94. I've seen 2 testarossas fillin' up in my life, both were on ultra 94. I'm sold........
