Default Re: Fuel injector cleaner?Check engine light?!

Anything higher then 87 octane is a waste,even pulling my 4,000 LB camper up hills I found higher octane not needed.

I put 20 to 35 gallon quality fuel injector cleaner (not the up to 20 gal stuff for cars)in at every oil change since new and have not had a problem.
I did add it then filled up? Maybe hook some turns and take off/stop hard try to stir it up a bit.
If you have onstar it will tell you the reason the light went on,Its still under warranty so bring it to the dealer if light stays on or comes on again.
