    In my opinion as a tech with 30+ years experience this is all I run. I've never had an oil related failure in my life with castrol products. And I've run the dog pi$$ out of all my vehicles. just maintained them correctly.

    Conventional oil is cheaper and I change it probably prematurely at around 2,000 miles or less. So i'll stick to that. I just didn't know if somebody made a brand of oil that's intended for shorter intervals and stronger protection for a motor that's going to be beat on really hard.

    With the racecar the oil gets changed once it gets to be a little brown on the dipstick. .... it never get to look dark brown or black.

    Rotella 15w40 T3 stuff.

    Its cheap, and I have a bunch of it in the garage. So far no issues with it.

    Seeing 30-40psi at idle makes me feel warm and fuzzy. Loss of HP be damned.

    but you pretty much have a diesel anyway, so it makes sense
