I would let the dealer change the first time for you after that change it your self.
The reason I say let the dealer do it the first time is the engine is sprayed with a clear coating of some type to protect it in storage and shipment. The oil filter is very difficult to break loose from the engine with this applied.
So let the dealer do it for you.
When you start to change your own oil, buy Fleetguard filters part number LF16035. This is the top of the line filter for Fleetguard for our trucks, if this is a 07. 5 and up truck?
I would then use Royal Purple 15W-40 diesel oil or Mobil Devaco 1300 15W-40 diesel oil, 3 gallons are required for an oil change.
I would also buy a Finger touch oil drain valve to make changing easer. Both the filters and finger touch valves can be bought from Geno's Garage.
One more item you may want to do is purchase an oil change sampling bottle to take an oil sample for a oil analysis. This is done every time you do a oil change to see if abnormal wear is occurring with your engine. The first sample is a base line then the others will track how your engine is doing.
