Well, added the 7 gallons of 100 octane unleaded, to provide approx 93 octane tank. I have to say it runs smoother, it has been hot here in San Jose, but I wasn't really expecting anything. I guess I will be putting this 100 octane, $8.69/gallon fuel in periodically. Seems stupidly expensive,

I really wish California just allowed 93 octane. It's silly they don't, yet allow gas stations to carry 94, 96, 100, 101, etc. Flew to the east coast a while back and 93 octane at Shell and Sunoco was like $2.90/gal. Meanwhile here in CA it's $4 for 91.
