Going to try a switch from Rotella 15-40 to Valvoline (maybe quiet the engine and shifting down a bit). Valvoline 4 stroke only comes in 10-40 and 20-50, so which would all you more Northern folks recommend? Or does it even make much of a difference?
Also,anybody use those magnetic oil plugs I see all the time on ebay and are they a good idea?
