octane question

[mercbuff]

since my truck is still new and i want to drive it all the time .my question is if i am just cruisng up and down the hiway and not putting my foot in it .is it ok to run regular unleaded gas .
the motor is a low compression motor and they have set up to run rich anyway . i put regular in it the other day by mistake and ran it at the drag races and didnt hear any pinging . i think you guys seem to know everything about these truck so i wanted yall

I would say NO .. Just because you cant hear it doesnt mean its not pinging

There are several things to consider... As a general rule it is best to run premuim. The PCM is an adaptive learning unit and will detune itself for lower octance fuels. I believe the manual requires 91 or higher. It is my philosophy to not to be frugal about the fuel requirements of a high performance vehicle I chose. Texas gas is decent and you must you can probably can limp around on 87 just don't tell anyone:twitch:
Doug replied over me.. He is right it may be running higher cylinder temps, and causing harm you can't hear. If all else fails follow the directions in the owner's manual. I think it requires 91.

keep those plugs sparking good and in shape...along with better engine and injector life. run 93 octane. dont buy a 33,000 dollar performance vehicle and skimp out on whats necessary to take care of it.
