ok, while i was at the dealership yesterday i asked one of the technician guys what exactly would higher octane do to my truck in terms of performance or mpg. he said absolutely nothing. he said that the 2.2s and even some v8s dont have the compression to do anything with the higher octane so i would pretty much be spending more money on nothing...he said 87 octane would be adequate(spelling???) wtf??? is he talking out his arse or what?

no i don't think he is wrong on that, i've from other ppl that the gas would make that much of a diff. to even spend more money of the gas. and to me thats good news living in Cali cuz i'm not going to spend almost 2 dollars a gallon just so it burns hotter....no thanks.

i think it depends on where u live out here in cali we got this crappy oxgenated gas which when running 92 i dont notice a difference unless im runnin on the bottle....in general though and this have even been written in certian magazines Hot Rod i think did one on this specifiaclly most vehciles dont get any hp gains from higher octane because of modern day ignition systems which give u the best possible spark so ure mpg is at its peak, and because of the way engines are built they actually produce better hp with the loweroctane because consumerslook for more efficency by todays standards thanthey did back in the 60's and 70's when the all mighty musclecars rulled the streets....hopefully that made some sense :thumbup:

93 octane does not add horsepower unless you have the chip which plays with the settings of the computer and will make the truck run poorly (knocking ) if not used. Otherwise the only reason to use it is to keep the intake and injectors clean it has special cleaning agents. I recommend using 89 octane(unless you have the chip, turbo, supercharger, NOS) this has some cleaning agents because the pump mixes 87 with 93 to form 89. Also, if you get gas that has been in the tanks to long it will actually start to lose octane so this way you are assured that you are not using to low of an octane. ALso, you should switch brands different brands have different cleaning agents. I personally only use (Shell, EXXON, Phillip 66, and Amoco gasoline).

I use cheap ass 87, runs just fine. I've run 93 a few times and the only difference I noticed was slightly better gas mileage. Didn't outweigh the price though. Unless your sh!t's turbocharged, I'd stick with the cheap stuff.

on 90% of the computer controled cars 87 octane is all you need to run..you would infact be wasting $$$ with higher octane... your comp. is programed to run best on 87...if you reprogram your comp...then go to higher octane...:thumbup:
