Premium at $4.85 on the way home from work in San Diego. The Harley eats premium. No other price matters.
I have a Jaguar that also requires premium. Bought it new 5 yrs ago and have never used it. I go to the dollar store and buy a bunch of bottles of octane booster. Put one in before every fill up. Never once heard a ping or could tell any difference. Has saved me a ton of money.
