Chevron? Shell? 76?

The biggest thing to consider is techron and octane. Be sure and choose a gas that contains techron to ensure proper injector cleaning to avoid harmful deposits. Most gas station's supreme grade or highest octane grade gasolines have techron in them. Namely, Chevron, Mobil, Shell, and 76. You should be using the highest octane possible in your car anyways with a performance car such as BMW, which is necessary and/or required to reduce premature ignition and help prevent engine knock. I personally go to Chevron and always fill-up with supreme (91 octane here). Depending on where you live the octane levels may vary. Depending on your budget, the final consideration you should make is price. It will not hurt to mix fuels i.e. if you put $5 of Shell in your tank and later down the road fill it up with Chevron as long as they both contain techron and meet the octane requirements. If you have to fill-up with cheaper grade gasoline at times that do not contain techron you can also purchase techron concentrate fuel cleaner to add into your tank. You can get these bottles at Chevron. However, it's not absolutely necessary if you normally use gasoline with techron to begin with. Hope this helps.. and don't worry to much about where you buy your gas.. just remember: techron and octane!
i used to use eitehr chevron or shell
i used to use eitehr chevron or shell but 1 time i went to chevron and they clogged up my fuel injectors for a bit and i never went back to that chevron and then shell just becam emore convientient and i always fill up early and theres shel and chevron right next to my house and im never going to that chevron again so . . . .

I never let my tank get below 1/4 before filling up, so on the occassion where I had to use the 89 octane it would not doubt mix with the 93 octane still in the tank giving me at or near the recommended 91. I can't believe that going to 89 octane once in awhile out of necessity is doing any harm. We car fanatics tend to obsess on these sort of things. ![[boxface]](/images/smilies/icon_smile_boxface.gif "Box Face [boxface]")

All Fuel is basically the same, it all goes through the same pipes, all the diffrent companies (Shell, Mobil, Hess etc.. ) get their gasoline from one refuling station, the only diffrence is that at each station theres a whole tank of additives that are added to make the gasoline more "unique" and/or "better" than what other companies use, so whenever i buy gas, i just make sure its 93 octane and im happy : )
I use chevron or shell. Chevron when I can just out of habit, but there is a place by my work that is cheaper which happens to be a shell station and I feel comfortable using their gas too. I never reall thought much abou tit and went anywhere really as long as they had premium grade (at least 91 octane) gasoline. The only place I always avoid is arco. Their gas is like water.
Basically, find a station that works good for you and stick to it. That's what they mean by not mixing fuels. If you find a good Arco (I've yet to do so), then stick to that particular station. If you find several, even if different companies, and the gas seems fine, then it's probably ok to mix it without any real harm to your engine as long as you stick with the highest grade. I stick to Chevron mainly cuz it's cheaper for the most part out of the brand name gas co's and since it's a brand name one, I'm less likely to get a bad tank of gas.
Gas is pretty much gas except for the additives. One major exception is the alcohol the the low priced (Arco) stations sell.
Since I clean and test injectors, I see the results of the various brands and fuel system mantenance.
Chevron's Techron appears to do a wonderful job in keeping injectors clean, it won't do much for badly clogged one's but keeps clean ones clean.
Wish we could get some of that 93 octane here in Washington state, just have 91.
My Corvette frequently pulls a few degrees of timing under WOT and reduces the horsepower.

Techron is no marketing ploy like some might think - The only thing that makes gas different from one another is their additives (or lack of). They all share and swap the raw form.
I use Chevron 91% of the time. Mobile is 2nd best bar none. Shell is the worst of the big names - this is known within the industry. I'm really suprised that so many people on this tread say they use Shell...![[confused]](/images/smilies/confused.png "Confused [confused]")

Gas is not gas - they vary quite a bit.
I would like to know what people think of octane boosters??

My father owned three gas stations (Mobil) and maintenance is the big issue. Some stations never remove the condensation from their tanks and you get watered down gas.
Right again. BMW does tell you not to use fuels with alcohol in them as they can damage your gaskets.
Techron is a Chevron product, and BMW does recommend Techron. You will not find it in any other gas.
Using a lower octane than recommended will result in poor performance and over the life of the engine can cause damage, I would think.
Personally I use Costco gas and add Redlines SI-1 injector cleaner every other fillup. (Costco sells Techron additive too, I think it is about $9.00 per case, four bottles) A good indication of clean tanks at your local station is fast flow of the fuel when you have the pump on and the handle pulled to the max.
My 04 cents (too long winded for 02 cents)
