Doesn't the manual say 89. So use 89 if you only have minor mods(engine wise) or running stock.

If you are boosting, 91+

Re: Need Information

I thinkthe manual said min require 87 but 91 for best performance! If I used 87 as daily driving(running stock), is it will hurt the engine?

I don't think it would hurt, but I've always run 89.
