RE: Mobil 1 for your Car..how bout for the Rifle
Correct, 40th formula tried and water displacing. I know it will "dry out" spark plug wires and get a vehicle started.
As for Mobil-1 I would think it would be fine, too. Only question is..........
As I know of no firearms equipped with an oil life/change monitor, how many miles between oil changes?
