Rotella 15w40
And since ive got two diesel trucks, i buy diesel oil everytime its on sale, 25 qts to do oil change on both. So, ive got LOTS of diesel laying around.
So, breaking in a fresh 440 with a .557 purple shaft, ive got five qts diesel, two and a half qts 50wt vr1, and a bottle of lucas breakin.
No problems with breakin, great oil pressure, (no surprise there, lol), and ran elevens for a couple passes before i pulled the breakin oil out.
Thought i had about 80 qts of oil in stock till i started to clean out and organize the garage. Turns out i had 180.
Well, I'm old and cheap. I was gifted two cases of excellent old (loaded with zinc) racing oil, some vr1, some pennzoil. Problem is, its mostly straight 50 wt. I'm still gonna figure out a way to use it.
