Hey everyone,
I've recently switched to premium and noticed my car's exhaust tips aren't as black as they used to be with regular fuel. I think my turbo DI engine prefers higher octane rated fuel, my manual allows for 87 octane but using 93 offers around 10 more horsepower. Fuel economy seems to be improved slightly, my "miles to empty" meter has been increasing after each fill-up.
Has anyone experienced similar results using premium fuel? I know some of these changes I'm seeing could be all in my head but Hyundai has released statements indicating the ECU can take advantage of premium fuel.
-Thanks
