you cant adjust the engine if thats what you mean, if you want to run regular i would use regular and see how it runs, if it starts acting up and not running right i would use octane booster to see, if not switch back to premium.

i used to drive my mustang over 30 miles per day on regular gas when called for high, i just used fuel injector cleaner more often.
