Premium fuel?

the big name gas companies have an additive pack they add to basic gasoline, like the kind you would get at safeway or costco. That additive pack has injector cleaners in it. The difference between premium and regular is the additives to quell detonation. These additives hurt the btu(s) regular gas has. In a sense you are paying for weaker gas, but it is gas that is safer.

premium gas is regular gas with cooling additives to quell detonation. Those additives hurt btu(s).
If you could keep out of boost you would get more power out of regular than premium.
not saying you should, who can keep out of boost. Some one with water/ meth might get away with it.

1: The sales of Premium are going down with the people that buy it for cars that don't 'require' it... thinking that it's somehow better or cleaner for their car... (which of course we all know is not the case) cars with high compression or boost usually will require 91 (which I believe someone already pointed out)
2: it's pretty much a misnomer to think the higher the octane the better, my truck runs on 116 but guess what, if I don't reprogram the ECU it will do nothing... I may as well be running 91 in it...
3: water/meth injection does a couple of things... a: it helps you run cooler b: it allows you to advance your timing... obviously this means more power...
Lastly, I'm no tuner, nor am I an expert on anything to do with cars, but I'm pretty certain that what i've stated is correct.
and that's my 2 cents... oh by the way.... I can't see unocal/shell/chevron doing this anyway... (as most people already agreed)... especially in socal... too many vehicles here require it...

At a ~13 gallon tank, and only .20-.30 more per gallon (depending on where you go) that's like another 1.5-2 gallons of gas for ~$2.60, which in the long run is more economic. I'd suggest you try it yourself in a car that doesn't call for it and see what your results are. Might make you a bit surprised.

Newer vehicle, designed for regular gas, person with basically zero knowledge of how cars work found it was faster without knowing anything had changed.
