Kinda' resembles my DEF usage.

I wish DEF had a 10-year shelf life like MotoMix. Generally speaking, how many gallons of DEF are you going through per year?

Well gee... I spend so much time pumping it out of the trucks DEF tank every Spring it's kinda' hard to tell.
A couple of years ago I did a hand calculation based on my records and I believe DEF mileage was 825 MPG.

One emissions fun fact I can tell you is that when the camper is loaded on the truck and I'm on the highway the truck does not do regens. It simply doesn't happen.
(Post turbo EGT's are usually between 800 & 950F under those conditions)
If I take the camper off the truck and run into to town to sightsee you can be sure she will regen... frequently.

It's almost like the trucks were meant to be used and not as commuter vehicles.

Or....the frequency that @rubberfish gets laid.

Hey, I heard that.

My silly 3500 HO-Cummins/AISIN for serious use?
No Sir.
For heavy interstate commerce FCA offers the Ecodiesel in a stout 1500 chassis. 💪

My 2015 is very similar. If I'm on the highway (loaded or unloaded), it seems to go forever before I see a regen. I see a regen approximately every 100 - 120 miles with strictly in-town driving.

I still haven't figured out the 2020, so I don't know how it compares to the 2015. It uses a low and high pressure EGR, which keeps the engine oil much cleaner compared to the previous generation, but seems to use more DEF.

Well maxed out the loader today. Didnt fully lift the rears but had to put it in 4x4 to move. Also currently do a regen. Need to figure out how to fix that.

No pics?

Had stuff to get done. No time for pics.

We had our neighborhood cleanup day. That's when the Solid Waste Department picks up yard debris, appliances, and other junk at no cost. I had all the limbs carried away and my neighbor put out some of the fencing that I took down.

@Electrojake, a buddy from Arizona called me today to tell me about the DEF refractometer he recently bought. He's the one with a 2012 Denali Duramax with a whopping 27,527 miles. His concern was knowing when to drain the DEF due to time and heat. His urea concentration read 35%. Good DEF should be in the 32% - 34% range. Even though his truck sits in the garage, the temperature today hit 100*F inside the garage. Anyway, I was wondering if you use a DEF refractometer to determine when to drain, or if you drain based on time?

When you have as much money as @Electrojake, issues like these are trivial.

He pumps DEF from the tank each spring, so I'm curious if he's testing or just going off time. I'm tempted to buy a DEF refractometer myself.

Neither.

He’s in a paranoid state and tosses perfectly good DEF out like cash at multiple storage units.

DEF prices have been going up! SuperTech is now $13.98. I went back to my 2019 records and saw that I was buying SuperTech for $7.88!

That comes out to a 77.41% increase....

At $13.98 / box....that’s $5.59 / gallon.

Bulk DEF at the pump at most T/A and Petro locations is still $3.99 to $4.19 tax in.

Let me clear that up for you. . .
I have a nice comfortable income... but near nothing for daily pocket money.
The storage units are just the tip of the iceberg when it comes to my many <cough> investment strategies. 🙄

I just read an interesting article explaining why automakers are planning for layoffs. The problem is a shortage of parts/materials. Automakers are also anticipating the market to cool and sales to decrease; however, if the market doesn't cool, then dealer inventories could take another hit. As you can see, it's been a very slow recovery.
