So the rotella T 5w40 is pretty good? I have a additive for conventional oil for break in. What oil should I use for break in? This is for a lq4 370 with a F1

I was running rotella untill i spoke with my engine builder and turbo guy, they both said the additives are not good for a gas burning motor. the only oil both of them reccommend is VR1 or Brad Penn. also NEVER use synthetic oil in a journal bearing turbo

2nd for Valvoline VR1 racing oil. After 2K miles or so then switch to a synthetic if you choose to. Gotta break in the engine properly 1st.
