I used Rotella/Delo oil exclusively in an 800+ HP 540.
After 3 years of many, many street miles and numerous track visits, although having no issues, I tore this engine down for a freshening up.
Internals looked brand new.
Re-ringed STD, new STD bearings, replaced solid roller lifters (.800"+ lift) and valve springs...back together it went.
