About the best you can do without taking a chance on violating the warranty is to use Top Tier gasolines, which many auto manufacturers recommend: https://www.toptiergas.com.

Thank you NicKey for you response, I don't DD the Car , I did run 3 of the 8 Summit ET Racing Series, temps were 70 to 85 in Match / April , now with temperatures above 110 plus the last month , I don't take her out , tho I did about 3 weeks ago early morning cruse in the Desert , temperature was around 90 . Since the 2 dates at the Track , I haven't run her hard .
Question normal driving 105 degrees nothing prolonged spirited (as they say here) with an occasional launch in 1st thru 2nd considered hard ?
I'm learning Thank you again for your patience and response.
