I don't think they do. Lots of these are trucks are owned by fleets, and the majority of them aren't interested in running afoul of the EPA. Lots of other folks never heard of FTE or any of the other groups who advocate tuning and just drive their stock truck.

I've seen quite a few now, in cube trucks and such that have 300,000 km's or better and DPF on.

The majority of stock trucks don't make oil. Mine never did.

I'd be doubtful of that word majority. Mine sure did, up to 6% on one anaylsis. Now, if you say the majority of owners don't know their truck is making oil, well that's a different story. If they don't have the oil analized they wouldn't know. I would submit that the design of the back cylinder injection DPF system insures oil dilution. The EPA report even says so, but they say it won't cause enough additional wear to have an impact on the useful life of the engine. i also don't think it an accident that the crank case dip stick on these trucks is almost imposible to read. I've been checking oil since around 1957 and I've never seen a more difficult to read dip stick.

Could be, but I don't think so. I'm no expert that's for sure but I sure thought that on the 6.4L the regen was accomplished by the two back injectors firing on the exhaust stroke. Now there is another system that uses a 9th injector down in the down pipe to fire the regen. Presumably with a lot less dilution.

I'm standing at all 8 cylinders do the regen.
