The first responder said "the higher the octane the higher the mileage"; that is WRONG. Numerous reputable consumer advocacy sources have said so. Using a higher octane fuel than what your car requires will NOT get you better mileage (see source). If your car specifies 87 octane, then buy that. Don't waste your money on higher octane fuel.
As far as brand is concerned, just make sure that the gas you buy has some sort of detergent in it to keep your fuel injectors clean. Most of the major brands have detergents in their fuel.
My source is the Federal Trade Commission website...

Another bunch of crap answers. Read your manual, put in the kind of gas it says. Millions of dollars were invested in designing and producing your car. Don't second-guess engineers who have way more knowledge than you do. Octane does not determine fuel mileage, because if it did no one would buy anything but premium. Octane is a measure of the fuel's resistance to preigniton, or what you hear as "knocking" or "pinging" under acceleration. It has to do with compression and ignition timing. It can damage your engine. Brand doesn't matter when you see the same truck unloading fuel into several competing stations.

After research, I realized that gasoline all come from the same source. All gasoline manufacturers are required to have the SAME amount of additives in the gasoline depending on season and region. Higher octane, lower octane, on a daily driven AVERAGE vehicle, octane DOES NOT MATTER. Octane is just a resistance to burn, meaning hotter higher compression engines require high octane. Regular vehicles do not.
My advice, get what's cheapest if you're driving a very subtle car. However, I do try to stay away from non-brand gasoline like "VICTORSINTHEMIDDLEOFDESERTGASSTATION".

The high octane gas is for engines with higher compression to prevent preignition ( knocking) If your car doesn't have a turbo or supercharger regular gas will work just fine.

its all about octane levels. The higher the octane the higher the mileage. To figure it out take the octane number you see on the pump and divide it by the price of the fuel. Generally just regular unleaded is the best bang for your buck !

There are already technical answers here, so i suggest CNG( Compressed Natural Gas) is the best for vehicle Mileage as well as engine's life is concerned.

bzzz person is right
why? because, newer cars use the oxy sensors to achieve the best mileage possible .
as far as brands, there are differences as they have different additive packs
Chevron uses tecroline its good they are most OK i don't like the cito aditives

Gas is gas ;it doesn't make any difference as far a brand is concerned. . as far as octane, follow the manufacturers recommendation .
what makes a diffeence in gas mileage is driving habits and vehicle condition

Depends on your car. Read your manual to figure out which grade of gasoline is best for your car. I haven't personally noticed a difference between the brands.

Follow manufacturer's requirements... As far as brands, I have noticed the same truck dropping fuel at different brand stations.
