Diff oils diff pressures?
Diff oils diff pressures? I used Castrol CTX non senthetic 10w 30 w/ a mobil 1 oil filter and my 6.0 (lq4) and my OP was always around 48-50 at idle.
I just did my first oil change.. this time I am using Valvoline 10w 30 w/ a bosche filter and the OP at idle is 42. I am wondering if brands can make that much of a difference even though its the same weight.
