This is my first diesel engined vehicle and I really don't know much about diesel engine oil requirements. Hence my original question. I'm just looking for ways to extend the OCI beyond 3000 miles. Like, what if I use a synthetic oil.
I've been looking at the oil shelves, and I see Mag1 All Fleet Fully Synthetic 5W-40. Mag1 website says it exceeds performance requirements of virtually all diesel engine manufactures including CJ-4/SM, CI-4 PLUS, CI-4, CH-4, CG-4, CF-2, CF, MACK EO-O PREMIUM PLUS '07, MACK EO-N PREMIUM PLUS '03, MACK EO-M PLUS, CATERPILLAR ECF-3, ECF-1, CUMMINS CES 20081, 20077, 20076, DETROIT DIESEL 93K218, 93K215, 93K214, MAN 3275, MERCEDES BENZ 228.3, MTU TYPE I, TYPE II, VOLVO VDS-4, VDX-3, VDS-2, GLOBAL DHD-1, JASO DH-2, ACEA E7-04, E4, E2, ALLISON C-4, JOHN DEERE, FORD TRACTORS, ALLIS CHALMERS, MASSEY FERGUSON, J.I. CASE & CASE IH, INTERNATIONAL HARVESTER (DIESEL & GASOLINE), KUBOTA, AGCO TRACTORS. Is this OK for my engine?
