Forgive me if this has already been discussed but I have a question about oil change frequency for my Tier 4 4720R. I am coming up on 100 hours on the engine. I started using Rotella T6 15W-40 at the 50 hour service and plan to stick with it in the future.
The owner's manual says oil change at 100 hours & every 100 hours thereafter & the oil filter every 300 hours. My expensive service manual says oil change & filter every 250 hours. My local dealer says every 50 hours for the oil & 300 hours for the filter and has no answer for the discrepancy between the owner's manual and the service manual (or the dealer's practice).
Is there a consensus out there??
Thanks!
