im picking up my new baby monday 65 formula s should i use 91 or 93 octane? will it matter?

 

[Rocky_JS]

for cruising around it won't matter. Run'er hard might want to add a little more octane. I just run whatever and have no problems with mine.

Mine runs on CA 91 with 10% ethanol, but I could run more advance on 93 if I could get it.
