Nothing but 15W-40 Shell rotella T here. Keith Craft recommends 20-50 oil in every one of their crate motors, i have a 302 crate, but not from them, anyways, dont give me the junk about bearing clearances *rolls eyes* this still dropped my temp guage half a line and cut lifter noise (that sewing machine sound all high lift cams tend to make) in half compared to 10-30 M1 synthetic. Saw several UAO's, one of them on a LS2 GTO where the guy ran M1 and then Rotella T and cut his wear metals IN HALF. I ran this stuff in my 170K mile Trans Am (LT1) when I had it and had to change oil ever 500 miles for 2500 miles b/c the previous owner used castroil GTX and had shitted the motor up with it. GOO poured out of the filter....
I use 5 qts with a WIX filter.
The reason for the Rotella T is b/c my dad used to escort oversize loads, he used old cop cars for his pilot cars. He did this from 197X until the late 90's. He experimented with a ton of oils and formed 2 opinions (he tore each motor down when he retired it) #1, quakerstate SUCKS! and is VERY messy.
#2, Shell Rotella was VERY VERY clean compared to any other oil he tried.
(He used to be an amsoil dealer, so he played with it im pretty sure, just on a side note).
The reason i went to a 15-40 in the 5.0 is b/c i was losing 1 qt per 1500 miles, well, doesnt matter WHAT oil i use, i still use 1 qt per 1500. My compression is 147-155, i plugged the PCV and felt over the open oil filler neck with engine running and BARELY felt the slightest hint of a warm draft, so no blowby to speak of, and the plugs are VERY CLEAN (except for some powery soot that all plugs get from burning fuel). Called ford, told them EVERYTHING about it, they said my forged pistons will cause that, 1 qt per 1-2,000 miles is normal for forged pistons, googled it, and apparently a LOT of people find forged pistons use more oil due to being made a bit looser. Nature of the beast i guess.

My oil had a little bit of a gassy smell when my fuel pressure was set a tad high. Nothing bad and no oil level rising or anything, but a LITTLE gassy smell is normal, just not too much, and the oil better still feel slick, or its NOT a good thing...
