OK, just did some reading...
Sorry Mark, not gonna tank this block right now, want to get engine running.
What I seem to be picking up is that higher milleage engines with low oil pressure issues can benefit from a heavier wight oil...20-30wt seems to be the consensus.
Stay away from Penzoil, Kendall
Good ones: Synthetics (Mobile 1), Valvoline, Castrol, Havoline...
There is also the trick of using a quart of ATF with an oil change and running that for bout 500 miles and changing again.
Not sure that I wanna be changing the erl that much...methinks I will see how things look in the pan and try some 20wt dino juice. Clean up the screen and check passages as well.
