| delo seems to be a pretty good oil my boss had a 7.3 ps and changed his oil maybe every 30,000 miles. once he hit 120,00 i dont think he has changed it since and it now has 185,000 and still runs great. i cant say anything about mobile 1. i personally us rotella synthetic and it idles quieter than when i used regular rotella
