IMHO
Delo 400 and Shell's Rotella T, are damned hard to beat. My N series 855 Cummins thrives on Delo 400 15W-40
Some people try and cure problems bass-ackwards. Because where I drove Quicksilver temperatures could hit 122F. I had a 5 row radiator built. The engine coolant temp goes to 185F max even climbing hills. My concern was to keep turbocharger oil temps within reason. So I have a 5 minute engine after-run. No way in hell am I paying premium money for a 55 quart oil change. Changing the element in the C-750L Luberfiner filters soot. So someone tell me -why- synthetic would be a bonus? Is it to try and cobble design shortcomings?
