0W40 instead of 10W30?

Al,
"I am a proponent of heavier oils-even though it may not be really necessary. You could get a little heavier "brew" by mixing in a quart of M1 15W50 (thats what I currently do)."

Have you had used oil analysis done on this brew? I would be interested in results.

Chris,

If this is a stock oil pump, I too, like Vader, see this as rather high oil pressure. I think the guage is way on the high side, maybe 10 psi or better. On most of my vehicles, the pressure at hot idle is around 35 psi.

For those interested in this subject, I just posted the results of my two oil analysis comparing Mobil 1 10w-30 and 0w-40 in an '02 Toyota Tacoma V6. Refer to the used oil analysis section for the results.

Incase you are looking for Mobil 1 0W-30, I just bought a case of M1 0W-30 at Kmart this past weekend. They have 0W-30, 5W-30, 10W-30 and 15W-XX not sure. One with the red cap.

It was on sale
