When did DEF become required ?
Thinking of upgrading to a DP. I want to avoid having to deal with DEF. What year models did it become a requirement ?

Just don't pour DEF in the fuel tank by accident like this guy did.
I just read all 10 pages of that thread (20 posts per page) and I will definitely be extra careful while putting DEF into the correct filler tube on our new coach. I know on the Prevost, they have moved the diesel and DEF fillers to the same opening so that both can be filled at the truck island. The DEF filler is just on the driver's side whereas the diesel filler is on both sides.
Mistakes can happen and it is apparently very expensive if you start the engine with DEF in the wrong tank. If not started (realizing a mistake was made), just removing the fuel, having the tank cleaned and refill with diesel will not damage the engine.
I have never noticed if the Diesel and DEF nozzles are different sizes to help against a brain burp. I know that the Diesel handles are green and the DEF's are blue.
MM.
