The Diesel oil is supposed to clean up the top end deposit build ups due to the high detergents in this oil. personally I am running some Rotella Diesel oil in my BMW for a month of straight driving and the oil turned black quicker than the Synthetic oil, so I guess its working, I plan to go back to Castrol or Mobil 1 fully Synthetic for my next oil change. I've also seen the ATF done at the Mobil shop I used to work at to "clear up the sludge" and I guess that works, and Seafoam FTW just plan to change your sparkplugs after. so do some research theres a few "old school" tricks out there.
REdline great oil I have it in the Bimmers diff now.
