Best I can get around here is 91... I may add additives (redundant?) because the manual talks about for the best life/performance use 93.

FWIW.

I'm Jealous!!! highest rating we have is 91 so even if you have 94 and 92, then I would say use 92, and once a month use 94 to save on the pocket book if you cant use 94 all the time .. if that makes sense... IWSTI GURUs what do you think about that?? Or would that mess up his ECU trying to learn timing each and every time ??

93 here in CT, go with the 94 if you can get it, the price difference has got to be miniscul
