There has been talk about it in the marine field, some newer ships are being built with the systems. For the time being our ship is safe since its owned by the gov. The old "do as I say, not as I do" routine.

I bet it's still harder to enforce the usage of DEF into boats and stationary machinery than into trucks :jester:

Having to carry a DEF jug on a boat doesn't seem any good :ohnoes:

glad to see you're deleting it. I haven't ever put any def fluid in my 250.

We are going Tier 4f on all our off highway engines next year.

So far, most are being handled with DOC, so we only have DEF in the SCR for a few of the smaller engines.

I have 32K miles on mine. I purchased two 3-packs of DEF off of Amazon in May of '15. I still have 1 of those 2.5 gallon jugs left, and my tank is about half full (guessing)

GM paid for 4 top offs while in for the free services. Conservatively, I am figuring that I have used 20 gallons of DEF in that 32K miles. My lifetime fuel average is 14.5 mpg, so it seems about right for the mileage.

This is the last DEF my Chevy will ever use :willy:

Since I purchased my Cruze diesel in May of 2015, I have put 2.5 gallons of DEF in it once. Right now it tells me that my DEF level is OK. I purchased it with 13k miles on it and it now has 40K.
