Hey guys/gals I got b16 (black head so I'm guessn a 95 si) engine and I'm wondering wat octane fuel I shuld use I've been using 87 but it jus recently hit me that I'm running at a high compression ratio (bieng that it's an si) so my question what do u put In your tank. I don't have any problems I just don't want that to be a cause of a new 1 . Thanks
