my cummins is a common rail ( pre emissions diesel) that's what I started using it in . It lubricates a 2 cycle ingine. I don't know why it wouldn't help lubricate a diesel & it's designed to burn
quite a few people in australia i know of from 4WD forums have run it for years in their vehicles and claim they are quieter,smoother and slightly better fuel economy whilst actually reducing sooty emmisions
