I guess thats alot longer than I figured it would. My old boss's duramax seemed to drink the stuff like crazy.It's really not a big deal. The tank is 5.5 gallons and is designed to last 10K-ish. If my 2013 Cummins is any indication, this estimate is accurate as long as you're running empty. Once you start towing it goes through it at a much quicker rate.
You can buy the 2.5 gallon containers at Wal-Mart for about $12, or fill up at many truck stops for $2.79 a gallon. I wasn't a fan of it at first, but it's much less of an issue than I originally thought.
Good link, just wish the Q&A was longer! It will never be enoughhttp://www.cumminsfiltration.com/pdfs/product_lit/americas_brochures/MB10033.pdf
All you ever wanted to know about urea
They did write this:saw on autozone had 2.5 gallons for like 15 bucks but states good to 12 degrees F.
so what you do below that temp in the 1500?
I would say... was the case with the systems placed on the 6.7 before SCR/DEF.No looking to make the truck last. everyone knows the fastest way to kill a diesel is put a bunch of emissions garbage on it.
