just read the owner manual.it recommend use atleast 87 octain for sedans but 91 for the coupes.hmm..why is that? i thought both engine are the same???

 

That's funny I thought the programing in the coupe is different, hints the extra HP. Timing or higher compression on the coupe. Or maybe its just a safety thing that coupes don't have.
