I used to use Rotella T oil in my tractors but after working a long day with the tractor I would have to add a quart of oil. Switched to John Deere Plus 50 and never add a drop before 250 hours. Like someone else mentioned the Shell oil also caused a white sludge. Personally, I would rather pay a bit more for an oil that lasts then having to pay to redo the motor later.
