Oil change

I usually do it like this on my DD15

Change water seperator, pump the fuel primer a bit, turn truck on

Change fuel filters, pump the primer like 900 times, turn truck on, preferably take for a quick spin, if not just idle it for a bit to warm up the oil.

Drain oil, whilst it's draining Change the oil filter, then refill with oil. Maybe grease the truck at this stage.

Turn truck on and make sure oil pressure is OK.

I never Change oil and fuel filters at the same time, I always turn the truck on and run it in between.

 

Which bypass filter system are you running?

 

Factory paccar. Amazing they include one now.

If I didn't, I would add this...

 

Do oil analysis.

 

Have always done it when it was warm. Not super hot just warm lol
