Motorcraft & Rotella for 6.0 Ford

[tsmay51]

It seems rotella gets a bit of a bad rep here at BITOG sometimes. I have used delo, delvac, premium blue and rotella in my cummins. I have used rotella the most though. I have noticed little to no difference in all 4 oils. Rotella is the cheapest and easiest for me to come by so that's what I run. Walmart around me carry delvac and delo but hardly ever have enough on hand for an oil change.

Cummins don't seem to as sensitive to oils as PSDs.

in this case the question of starting times is subjective and dependent on many outside factors
