Something about this "Limp Mode" stuff doesn't sit well with me. Almost like Big Brother Socially Engineering me with something else. I mean, a perfectly performing engine being "limped" because it's emissions are out of spec... (and not harming the engine) Really!!!!!
Im amazed someone hasn't figured out a way to defeat the Limp mode feature in relation to DEF.
Sorry, rant mode = OFF.

My question would be why bother? The cost is minimal at the pump $2.79 a gallon around here and even the 2 1/2 gallon jugs aren't that much if you look around $9.95, $13.95..
Also, the limp mode isn't instantaneously applied... you got to be really dense or something to ignore the warnings and just refuse to fill the tank. There just isn't anywhere in North America where you can't find a pump or a jug within 2000+ miles and if there is and you're headed that way; use a little common sense and carry a jug...
As a note... my truck get about 2000 miles between less than 1/2 full warnings... The last was 2375 miles but I wasn't towing the entire time.. that would lessen the mileage a bit.. But even if it cut it in 1/2... I'm thinking that somewhere in 1000 miles I'd find a jug... I know I'd have to fill up with diesel 3 times in 1K miles if towing..
