Been doing some experimenting and have concluded that premium seems to work best for long periods of continuous idling. With regular I seemed get an occasional "bump" while idling, with premium it's gone. This engine continues to run fantastic although Joe's Bearcat is quicker out of the hole than mine. Top speed seemed close between the two.
