I was curious to know the benefits of mixing 100 octane fuel with 91 (I live in SoCal). Was thinking about mixing 5 gallons. I have done some research but would like to know the opinions of others.

Thanks guys

You can do it but its only going to affect anything when you are full throttle (obviously). If your daily drive is a lot of highway driving where you are just cruising, its not going to make much difference. It's just a matter of cost, obviously the 100 octane the car will run stronger (if your tune is good.)
