And also why GM stopped selling their ZDDP rich EOS (engine oil supplement) then re-introduced is as an "assembly lube" a while later. Whatever is takes to get around the EPA.

I run Brad-Penn 10w-40 in the K10 and it seems to do OK.

If Brad Penn Grade 1 will work in those conditions, then it should work just fine in anything else.

Great point....
The mutha of all scuff applications.

Brad Penn Oils are a great product...Both the break-in grade & the run products.
Most top machine shops stock it.
