1 year agoDepends on the car… My 92 buick that’s supercharger with an ancient obd1 computer system with no knock sensor? I’ll mix 93/89 to get 91 but I wouldn’t risk anything lower since I don’t wanna crack a piston. Modern cars? High comp turbo engines can run 87 no issue.
What does the novber upgrades give?
