I am fast approaching a point in time when I will need to install new motor oil in my GEP P400 engine. I have read the arguments pro and con until my Walmart readers fogged up. So I thought I would start this thread to ask for expert opinions.
My P400 long block arrived from GEP in a crate with, surprisingly, the correct amount of oil in it. I drained this oil in order to remove the cast aluminum pan for bung installation and the oil that came out appeared to be synthetic. It was a yellow-green color and had a weird smell. Didn’t really look like oil at all. Kinda glad I drained it.
I have always been a big fan of Rotella, because a long-time mechanic who I trust will use nothing but Rotella T4 15-40 in his Diesel engines. So my question is, does synthetic have any advantages?
