I have a 5.7 Vortex engine with a small leak from rear main seal, and maybe back of oil pan, or perhaps just one. It's maybe half a quart per my 5k mile oil change.
I use PUP 10w30, and I'm very strict with my vehicles, they only use the same oil that I decide on never swap brands due to not liking to mix oil ( regardless if it's harmful or not ) which leads to the question, is it okay to mix it with a G2L oil? I'd normally repair the seals properly but as of lately I work 100+ hrs weekly. And I do all my own work, so a shop touching it is out of the question since it's restored and highly modded both Engine and trans, heck even have a coolant filtering kit on it.
I've read many postings on this site giving it good rating, but not one particular to my concern.
