100ron. Then add a piggyback that leans out AFR. Result: a little more hp, a little more mpg!

I normally run 87 but tried a tank of 91 last week.I have no real data but seat of the pants my car ran smoother and had a little more pep with the 91.

This could be placebo so not sure

I got better mpg with the 87 but thats because I was running the snot out of it on the tank of 91 with lots of full throttle blast.

I'll just stick to 87 and run a occasional tank of 89/91

Oddly enough I just filled up with 91 a few days ago for the first time in this car after running 87 for the last 8 months. Car does seem to be running smoother and I too did notice a little better acceleration.

Doesn't hurt anything and I appreciate the extra little power that others have noticed as well so I will just keep on running premium for awhile.
