Hi I'm looking a recommendation on a diesel oil preferably synthetic. This is for a new to me 1999 Case 580sl with a cummins turbo diesel 3620 hours on the clock. The manual states cg-4,cf-4 in a 15w-40 weight.
Mobil 1 Turbo Diesel Truck 5W-40--- is cg-4 but not 15w-40 or certified for cummings
rotella t6--- Is certified for cummins diesel but don't said about turbos and not 15w-40
I'm new to diesel oil and this tractor so i dont know how important oil weight is but the tractor wont be used in winter time.
Also is every oil rated for turbos.
