How much DEF to add?

saws all the dpf filter and turn it in to a retro glider

 

Nevermind I can't find the fuse box in this 579..

 

DEF goes into the California water supply. Delete your truck and run around the CARB inspectors.

 

salt in your fuel and pepper in your def makes exaust taste and smell better

 

Not sure why more people don’t use the concentrate.
It really is cheaper over the long run. Sure, the pre mix is easy, just pump and go, no mixing.

 

The obvious answer is as much as physically possible!!!! Can’t have enough of a good thing right?!? Keep adding till it pours out the top.

 

I once knew a guy whose company wouldn't give him any time off for an absurd period of time and his truck started using a little coolant so when he got real close to home he dumped a couple gallons of coolant in the oil .
Twas vacation time then .

 

This is flat out hilarious stuff. Started it last night and was still chuckling when I tried to fall asleep.

 

Just make sure you don’t get any of the red stuff.
Mixing the red and blue will cause problems.
Hear of a driver that did that, made his turn signals stop working.
