Can You Bypass Def?

LOL.
How far chemically different a human urine from the actual def is, would be a valid question. I am sure they smell similar.
In any case, there is plenty of free organic Def jugs on every truck stop.

 

Just gotta monitor your water intake to make sure the ratios stay correct

 

They don't sound as good either.

 

Yes, you can bypass DEF, just buy a truck built before 2010.

 

The ratio of fuel to DEF is only 50:1. So you use roughly 4 gallons of DEF per 200 gallons of fuel. Not sure what the big deal is with some people. It is simply a cost of doing business.

 

yep i have never even had mine below the halfway point before

 

If you are just looking for a quick fix to get it back to the shop or to a DEF pump you can unhook the speed sensor from the rear of the transmission. But doing so you loose your speedometer and jake brakes and the truck becomes completely gutless. I know this works on Volvos because I've done it. The truck is still in derate mode, but doesnt know you are moving.
