Diesel engine maintenance suggestions.

Thank you for helping with this question.
What maintenance or preventive things should I be doing for my 2012 ML350 Bluets 4matic?
Newer to the world of Diesel engines. It has 118k now. Only done an oil change, not added DEF. Had it for 1,5 years.

Oil change every 5k and not a mile more is my first recommendation, and be sure to use the correct oil so you don't get too much ash in the exhaust system.

The owner's manual in my F-250 has the first scheduled maintenance at 10,000 miles and every 10,000 thereafter. This includes oil/filter change and inspecting other things. I have never gone that long before changing the oil and filter before. With all the new synthetic oils, I am wondering if people think that it is acceptable to go for 10,000 in between oil changes? After all, that is the factory schedule. Thoughts?
