Oh god, we should all go dump our auto trucks for a G56 model, Not!!!! Snoking
I didn't tell anyone to dump their auto's. You should have whatever truck floats your boat. I have a simple tradesman. Didn't want the extra cost of a Laramie. But you should enjoy the conveniences of your truck.
I almost wish my truck used more DEF. Or I wish there was a drain cock on the DEF tank.
I have concerns that DEF left in my tank too long when not using my truck will go bad and cause problems.
But I read (and this gives me some comfort) that as the def deteriorates, the SCR system detects it and squirts larger volumes of DEF into the exhaust stream.
So it MIGHT be that a truck using alot of DEF got a hold of some old/partially degraded def?
Won't hurt your truck any tho
