Keep or sell 2016 FL Cascadia DD15???

It's not cheap it takes them like 5 hours and they do change the oil after. It's something like $2,700 that includes the oil change.

 

A truck can go from a money-maker to a money-loser in a single repair, that's why, in the future, I will be buying new or lightly used modern trucks.

Older trucks might save you some on upkeep and uptime, but a lot of them burn a lot more fuel, erasing a lot of that bottom line advantage.

Since you are interested, I'll link my thread.

I would be VERY cautious about putting any sort of cleaning chemicals through a truck engine via any method (fuel, oil, DEF) unless they are approved by the engine manufacturer. Chemicals can interact with seals, gaskets, filters, sensors, and many other parts of the engine. Especially exhaust systems.

On old iron that's not as true. They are more solidly build and less susceptible to chemical mixing issues because they have fewer fiddly bits.

 

Today's trucks are a gamble after 500,000.

 

Like anything else, the emission systems require maintenance. Too many folks don't understand that. Turn key and go.

 

I think 250,000. I had 2011 Cascadia it even had 600,000 miles part and labor warranty on the engine. That year was first trucks with DEF. That truck was a disaster in repairs. I got it used with 460,000 miles and it was one repair after another. Even with all the warranty work Detroit did it was a never ending repairs. Finally at about 640,000 miles the emissions box when bad. Those are $12,000 to replace. I have heard other people say their emissions box went bad 600,000-800,000 miles. I'm not sure the engine are worth fixing as they get older. But now they have that cleaning foam and they know how to fix the emissions systems better. The probably with my truck was the DOC filters went bad and they catn be replaced. Detroit built then into the emissions box. Seem like a really bad design to me.

 

Follow your instincts.
