Dx3 Oil Change - VERY Easy!

Just finished the first oil change on my 2018 DX3. It was one of the easiest oil changes ive ever done on anything.


First off i was thinking...i dont have a pan big enough for 6 gallons of oil. The trick is, you dont need one =). When you go to drain the oil, drain the rear (high) plug on the pan first, about 2.5 gallons comes out. Then do the front plug where the other 3.5 gallons will drain. Easy and no mess.


The oil filter looks like it will be tough to remove...not so. Use oil filter plyers and it will come loose. Carefully lower it down and it wont even spill.


Fill and throw on the new filter and fill with oil.


Easier than changing the oil on my Ford Raptor.

You changed the fuel filter and fuel/water separator too right? Should change them all at the same time, at least I do.

And air dryer filter. Just make sure you bleed all the air first.

Agree! The hardest part is lifting a 'mostly filled with fresh oil' new filter up from beneath the rig and getting it started on the housing threads (assuming you put fresh oil in your filters before installing new ones). A hundred times easier than R&R'ing the filter on my ram cummins.

Also, X2 on what the other guys above have said. Do it all and be done with it.

I did get both the separator and the fuel filter but I only have 7,000 miles on the coach, it would be a waste to install them now. Instead I put them in a compartment. Will do next oil change.

I was wondering...is there a def filter? What if some grit got in the DEF tank?

Are these the two drain plugs we’re talking about? One upper, one lower?

My Force with the 8.9 has two oil drains one forward and one at the rear of the pan.

I’m thinking the L9 in the XL may not. One of the several differences from the DX3 engine that I am beginning to discover. The plug in the second picture appears to be on the bell housing, so I don’t believe I should mess with that one. Just trying to confirm before I jump in screw it up somehow.

Interesting. Looks like you only have one. Better get a big drain pan! Or just use that valve and turn off between containers.

I had installed a Fumoto drain too, makes life much easier with oil changes.

I have a 23 qt drain pan. Just short of 6 gallons as fate would have it. So, that last quart ought to be fun!

Changed the oil in my DX3 yesterday, second time since owning it (yearly change since I don't put more the 20K miles/yr on the unit). Tried your trick, drained the upper first, dumped the oil, then drained lower, moved the container, and then put a hole in the filter to let it drain completely. Install oil filled filter, add oil and then grab a beer. Whole process took about an hour and dealing with half the oil in the waste pan makes it so much easier.

Actually I didn’t even poke a hole in the filer. Just loosen it and carefully lower. Zero spilled out.
