What octane do you use in your Pontiac?

  1. 1. What octane gas do you use?



Recommended Posts

Just a curious moment to see who uses what and reasons (ie tune, etc...)




I use 87 in the G6, no tune or anything to warrant upper octane.

87 in the Grand Prix and 89 in the Phoenix. Anything less in the Phoenix and it will auto ignite when I turn the car off and keep running for a few seconds.

87 per manual due to tune.



Might have it tuned to 93 when i install headers



Farther down the road defiantly 93 and maybe E-85 if I'm feeling fancy

Sta-bil has a new ethanol treatment for older engines. In addition they have 104+ octane boost. I use 87 and 104 once a month in the GTO (as its system cleaner as well.) 93 is manditory for the Sunbird.
