I am confused..please advise.
I always thought the thicker oil like Castrol 20W-50 would show a higher oil pressure reading than a thinner viscosity, such as
10W-30 but the thinner oil may actual flow more volume. . At 2200 miles I am considering switching from the 20W-50 to the Mobil 1 15W-50 in my 351W . The Mobil 1 seems much thinner in texture.
