Oil Change Question?

Hi Tom,
I am in the same mileage boat as you, maybe even a bit less. I also use Valvoline 10W30 VR 1 oil (part #VV205 ) with either a Wix or Baldwin oil filter. I change my oil in the late fall before she takes a nap. My reasoning for the fall change is because of all the acids in the oil that have accumulated during the Spring/ Summer driving. I don’t want that stuff sitting in the crankcase during the Winter. Food for thought...
Take Care,
Greg
