Rotella 5W-40 full synethic is an excellent diesel oil. I've used it for 24 years and have had no issues.

Been very happy with the performance and protection this lubricant gives. Oil samples look good every time.

Great oil for my 6.7 turbo stroke.

6.7 turbo stroke. Analyzed after 5,000 miles. Plenty of add pack remains. Can run longer but I don’t.

So far so good! lol. First oil change on F-250. Meet API CJ4 standards. No ticking after I changed @ 4k miles.
