How does motor oil get its winter viscosity rating like 5W, 10W, etc? How are foam and aeration tested? How does it hold up to severe oxidation and what corrosion protection does it offer? What effect do oil additives have on metals they claim to protect? These are just a few of the questions answered as Gale Banks continues his lubrication education in Speed School, Episode 3 of our 4-part series. Links below.
