DEF Gauge

Anyone have any issues with the def gage reading inaccurately?
i’m pretty certain that my def gauge has not moved in the last month or so. And honestly I’m not even sure when was the last time I filled it up.
i know for sure I have done 2 complete regens in the last month.

DEF is used mostly during towing or heavy use. Just cruising does not use so much. Pretty sure you are ok.

How have you been using the truck, what is your duty cycle?

Start towing and you will go through some def.

duty cycle just another term for how you are using the truck. Sounds like you are just hanging out waiting or warmer weather.

About all I am doing for the next couple of months too.

I have noticed the same thing on my 19. DEF gauge looks like it not moving at all. Well after a few more trips, it finally moved enough that I am satisfied I am just not using alot while not towing and it being cold. I also noticed my work truck a 14 6.7 doesnt seem to be using the def it usually does in the warmer months.You should be fine.
