2 1/2 years i have run the 87 octane in my car, and have had 2 members but on the readers to look for knock there is non, yes its only $.32 per gallon more but i fill 2-3 times a week and more if i am going out of town, OP do what you want, it will run as long as any other car out there on 87 octane. IMO
