I use 93-94 octane (Sunoco and Exxon usually, sometimes shell or mobil) regularly...However, I noticed there are differences in the performance of the car when using different brands of gas...

Does anyone else have this experience? Which brand do you feel gives the best performance for your car? thanks.

 

use Chevron. heard nothing but good things about chevron.

 

I use Chevron...just something about that Techron stuff. It works pretty good!

 

Yup Chevron with Techron 93 Octane

 

what makes the techron 93 special...anyone know? i don't see that many chevron stations here in jersey, so any best second choices?

 

Arco runs great for me, (it's also the cheapest in town for premium), but my second choice is Chevron.

Mobil is usually ok,
I don't trust 76 or Shell,
I never go with non-name brand stations.

 

76 with pro power is the best, better acceleration, throttle response and mileage, but techron cleans the engine, but it makes the car lag. try both and you will see the difference, i can feel the power from 76 but i can't see the cleaning power from chevron. just my opinion. used to use chevron, but now i have changed.

 

a while back i heard 76 wasnt good for our VQ engines

 

thats what i heard about 76 gas from some people on the board , but from what i've tried it doesn't do anything bad to my engine, no knocking, pinging or anything. and i thought all gas was the same, other than the additives so i don't know what to believe. but i switch around gas anyways so its ok.

 

the reason i asked is that i read that not ALL gas is the same...someone correct me if i'm wrong here:

the performance of a brand of gas depends on the original ditillation process involved, where the (the "lower vaporizing") vaporization temperature of one of the components affects the overall actual effectiveness of the gasoline.

 

Well, actually YES and NO. All gas stations get the SAME gas from a supplier (whether it's 89, 93, etc.). What makes them different is what additives and detergents the gas stations themselves add to their gas. At least this is true for the North Texas region.

 

I've always had good luck with Amoco and Shell.

 

I like Chevron Premium. That is the only brand of gas I use.

 

I had three maxima's and all seem to have more Horsepower from Amoco Super Premium, but Chevron w/ Techron is right there with it.
Kind of hard to pick a winner here because both are great!!

 

Best gas companies for the max would be mobile or exxon.

my car runs best with these two companies.
I put chevron in my car once and it hated it

 

Chevron and Texaco use the same gas, same company.

Exxon and Mobil, same stuff...

 

So very true

But I thought it was shell and texaco tat were the same stuff

 

80 octane is good....make sure it's leaded.

 

I've been experementing lately. I used to use exxon religiously. here are my findings: exxon/mobile gas= blows thru car like bad taco bell, shell= best performance/extreemly high prices, chevron= right behind shell in performace/price comparable to exxon/mobile, local municipal airport= 148 octane airplane fuel/$3.24gal/WWWWWEEEEEEEEEEEEEEEEEEEEEEE!!!!!!. anything else is watered down dino ****.

 

i always use texaco, dont know just do. Hess gas sucks bad.
148 octane kiss your o2 sensors good buy

 

Personally, I have only used that 148 octane gas in my lawn mower. I don't think I would have the guts to put it in my car.... yet An old friend of mine put it in his truck, That sucker would let out a wail like a banshee in full heat that was just blue balled.

 

I am a person who will either use Mobil or Shell.
