maybe 87 burns too quick and and explotion is happening before the piston gets to the top. Next fill up reset the tripdometer and add 89 octane and see if that helps slow down the explotion timing to where the piston is on top.
How many miles do you get out of a full tank?
I get at least 360 miles per tank, but I'm not sure how much fuel I have left?
The low fuel light doesn't come on, so it probably still has 2 gallons.
I will know the answer on my next trip to the gas station. it let mine warm up for at least 10 minutes in the morning and I'm easy with it, drive the speed limit ect..
