What do you think is the best gas to use for our cars and why?

dogfight

I use 87 octane Citgo gas in my '98 2.3CL - because it runs fine and Citgo DOES NOT import any of its oil from mid-east sources.

Depends on what car you have. If you have a First Gen CL, then 87 octane or higher is fine. If you have a 2nd Gen CL.. especially on the Type-S... you need 92 or higher.

Brand is really a matter of preference. Gas is all very similar, so just worry about the octane. You'll get 20 different answers from 20 people about brand since a lot has to do with location and convenience.....

Here in Colorado, the highest octane available is 91. anyone know of a good additive to use in order to make sure problems do not arise?

from what ive heard... the major companies are all fine ie. exxon, texaco, citgo, sunoco etc..., its the second hand ones that you have to watch out for. from what ive heard the fuel truck has sort of a runoff area which catches excess gas when pumped so its not lost or spilled and the second hand stations/companies buy that gas at cheaper cost. so therefore that gas could have a combo of 87-94octane gas making it less pure.

again!!! this is what ive heard. maybe im right maybe not maybe someone else can shed some light

i personally use texaco, chevron, or exxon

You should be fine with 91.... you're better off with 91 then using 91 with any additives.

Mobil Super+ 93 octane...it's the only 1 above 91 on Long Island next to Sunoco Ultra 94

i think i've only filled up ONCE not using Mobil, and i think it was Exxon, which is the same company anyway lol

I remember when I had my old Corvette, I used a can of "105" Octane to help bump up the octane rating. It worked great with no ping. I don't know if it's still around, but there must be similar products. Check any automotive store. Pappy

We can't get Sunoco 94 here in FLA.

I usually use Chevron premium...I did notice a slight difference in performance on my '98 GSR whenever I filled up with it. I did get the best mileage though while using Shell premium, but I usually stick to Chevron since it's more convenient for me. Didn't like Mobil, so stopped using them.

Then again, maybe I'm just crazy and the differences are just in my head...

CO-CL-S

An engine does not need as high an octane gas at altitude as it does at sea level. I haven't experianced any problems with the Colorado gas (pinging or mileage). YMMV

The biggest difference with "off brand" gas is the lack of all the additives like detergents, etc. Most off brand gas comes from the same refineries as the majors, but doesn't get all the treatments, hence the lower price.

I'm used 76 premium since I got my car back in March and just switched to Chevron premium to try it out and I noticed my exhaust is louder now...don't know if it's the gas or what...runs great with both!
