Is anyone running nmf (no more friction)? Someone showed me a video about it. Is there a need for it in a duramax.
It said that it changes the electrons and protons in the metal. Gonmf.com is the website. Can't find much information about it in duramaxs.
I have been using rotella t6. Going to switch to mobile delvac and try that. I have the typewriter noise with rotella.
