i run 5-20 wal mart @ 2.74 a quart year round in my 3 vehicles,,40 psi @ 3k is low??? sure you can put thicker oil in for summer but for what?? more psi on the oil gauge??? it takes HP to spin an oil pump.."you only need 10 psi per 1000 rpm" smokey yunick.. soon as WM starts selling 0-20 cheap,i'll be using that too !!!
