what type of gas do you use and what kind of mileage are you getting from it?

i am currently using 76 gas 89 octane and get 27-30 miles to the gallon on first 4 tanks.....

how about you?

using Shell 89 Octane and getting between 33 and 37 mpg in my xA on fillup probably 13 or 14 by now (just over 4k miles since July 29th with a week of it being in the body shop)

Chevron 87...about 27 mpg. i have about 1400 miles on it now.

I usually use Arco or 76 (87 octane). Today I filled up my XB with 800 miles on it and calculated about 26 mpg. Most of the driving was on city streets with A/C on about 90% of the time.

Since refiners routinely trade finished gasoline back and forth, there is no point to patronizing one brand over another. All gasoline is refined to meet a specification, and unless you are buying race gas the refiner won't spend a penny to make their gas any better than their competitors. The money is spent on advertising to make the customer _think_ that there is a difference.

When I was in college one of our projects in power systems was to conduct tests on various fuels. The results were completely uniform between brands.

The only difference in fuels is at the point of sale, and that difference is contamination. If the station looks dirty, the chance of getting contaminated gas is greater. I tend to avoid dumpy stations for that reason.

So what happens when your in Blythe? They all seem pretty dumpy.

Chevron 87... I average somewhere between 275~300 miles per tank.

I use 91 on my matrix and get about 27-29 miles per gallon and I am at 5000 miles now. I can get 30-32 if i drive it easy and shift a 4k, but that is no fun.

I usually use Arco or 76 (87 octane). Today I filled up my XB with 800 miles on it and calculated about 26 mpg. Most of the driving was on city streets with A/C on about 90% of the time.

do you ever hear pinging with 87 arco or 76?

thanks

arco 87 makes my work truck ping like a mo!

Chevron 87 and I get 32 - 37 mpg. Also, I have gotten roughly the same mileage since day 1. I have seen others write that their first few tanks got sub-30 mpg, but then improved from there.

i am a diesel mechanic in colton so cal {909} . i service several name brand fuel co's trucks. when i ask the drivers about where the fuel comes from they all said the same thing.i in my area {909} it comes from the Rialto site . just south of the 10 freeway on riverside in rialto . they (the drivers ) say the only 2 diff's is addatives that are brand specific ( i.e. shell , chevron ...bla bla bla) and water in gas station undergroud tanks.( i.e. leaky tanks)...

do you ever hear pinging with 87 arco or 76?

Never had any problems with pinging using 87 octane at either gas station.

I know this thread is a bit old, but was wondering with the recent increase in gas prices if people are still sticking to their favorite brands or just getting the cheapest gas.

Also, is one brand of gas or higher octane really any better?

WORD OF THE WISE:

If your in the South, avoid RACETRACK gas like the the plague. Its typically the discount fueler around here (at least in TX). I have know so many folks (including myself...not the scion) that have had pinging engines because of their gas. Pay the extra 3 cents, ITS worth it!

That said I usually stick to diamond shamrock, chevron, on conoco 87 reg unleaded... have notice really no differnce between them all. I get between 28-32 depending on city vs highway.

Hey - No BP (formerly Amoco) :?:

I only go there because it's next to my house :P

Shell 87 and I'm getting about 31-32 MPG. Got over 5600 miles on the box. Thinking of swithching to cheaper brand coz' of this thread :D . Shell prices are the highest in SoCal. But its the one nearest to my house....dammit!

Exxon 87 or ARCO 87.
I have about 2100 miles and am averaging about 27-28 mpg. :twisted:

exxon or mobil

This poll is basically worthless.


Sorry, but the variables that dictate your gas milage vary too much. Driving style, car type, engine milage, local terrain, percentage of highway driving, and duration of trips all affect your gas milage. These variables will have a bigger effect your gas milage than switching different brands of gasoline.

Gas is gas, regardless of brand. The only thing you need to look out for is contamination. Octane **shouldn't** make a difference in your milage. You should be using as low of octane as you engine can use without pinging.
