Nice! What octane fuel are you on?

I can't find anything other than 91 here in California and it seems like all my cars are slower than manufacturer specs. Or I'm a really bad driver.

 

93 all of the time. I also will throw in 5 gallons of 98 about every 5-6 fill ups. Which it’s about that time. There was a thread I found some useful info. Most guys were in Cali. I’ll link below. I’m in mass every gas station has 93 fortunately. Pure gas app helped me find the 98 about 15 min from where I live.
