I and others have posted several times........you can buy the SCR fluid (urea) from any truck or car dealer formunder $10 per gallon......did your paperwork indicate how much fluid they used at the 5600 mile service?

I suspect that your dealer was unfamiliar with SCR fluid on your 2009, and it wasn't filled at delivery.......unless you have a bunch of idle time, you shouldn't have used that much.....

Next time you see a truck dealership (Freightliner, Peterbilt, Kenworth - NOT International) or a Cummins or Detroit Diesel shop.....stop in and buy a jug.....1 gallon, 2.5 gallons, or 5 gallons.......

I put in a gallon early on after I found that the PDC didn't fill mine initially.....I kep a jug in the garage, and have never used in 23000 miles....

Good luck !
