Just had my 871 inframed and wondered how many miles I should run before I change oil?

== After first crank, it should be run about 50 miles and then changed out. This gets rid of all the assembly lube and other solvents that were used during the rebuild.

== After that, Normal oil change intervals should be based on fuel mileage...

== The engine brake should NOT be run on its highest setting for the first 50k miles.

== At 50k miles, the overhead valves need to be re-adjusted and then you can use the engine brake on high after that.

Ok. Is rotella still one of the better oils for these cummins or is there something better out there? I usually use donaldson filters heard before maybe they were little better then fleetguard but I can't prove that.

As far as the oil.. Rotella-T is just fine.,.. and if it is de-mandated then 1 gallon of gear lube 80/90 will help to extend the life of all the lubricated components too.
