First time I have owned a diesel & enjoy it very much. Question is what and when do you add fluid or Blue stuff to the cap next to the diesel ?
What is the intent of that additive etc...

Thank you

Plenty on that-- Google: "SCR" and you will see that all modern diesel trucks utilize SCR technology to meet NOx standards. It's a great system because it enables engineers to tune diesel engines to achieve maximum power. The DEF tank holds enough fluid to get the vehicle through to the next 10k service interval.

Keep adblue tank full all the time, every oil change, do oil change no later than 5K, OM642 likes fresh oil good lubrication.
Change engine filter every 20K, not 40 as book recommends. This engine need fresh air. There's a TSB about air filter.
Good luck.
