What is it with DEF?
Just what is the Diesel Exhaust Fluid (DEF) ? What does it do and why do I need it? This is my first diesel and I never heard of it.

It appears you have a 2007 model year Mercedes Benz Sprinter engine. I don't think MB used DEF in your engine in 2007. Best to be asking a Mercedes Benz dealer. The big thing is using the specified, required, lube, i.e. synthetic motor oil. MB, like most european diesels, are very fussy about that!!!
I think you will get much better information on your Sprinter MB diesel at the Sprinter Forum.
