John Deere Plus 50 15w-40, why, cuz we have 55 gallon drums of it and run it in everything else that is diesel. Ran it in a 87 dodge mini van and it has about 290,000 on original motor.

Rotella 15W-40 normally. Switch to Rotella Synthetic 5W-40 when it is really cold in the winter months.

 

[BlakeDavis]

ran rotella for about 45000, switched to delo mostly because it was stacked closer to the truck in the shop and because i was curious as to whether or not it would have the same odor for the first 1000 miles. It doesnt, so i think i will stay with the delo, both were 15-40w
