I add DEF fluid at every oil change which is typically 2 gallons using only DEF from a container and at 96k miles no issues to date. And for the naysayers it doesn't mean I would have problems using bulk DEF, but I'm just more comfortable with the container stuff.
You only fill up every oil change? How often are you doing your oil changes. There is no way I could go 15k between DEF fill ups.FishOnOne wrote:
Running exhaust brake is still a common practice on the 6.7 cummins to prevent soot build up in the turbo
LOL!!! Too bad the 6.0L Powerstrokes didn't have exhaust brake to "clean the soot build-up" on them since they were prone to soot build up on the VGT veins. I wonder if you have to run the exhaust brake on the new Powerstroke since it is VGT now too.
I change the oil between 5,000 - 7,500 miles.
The 6.0 PSD I had never had the turbo touched, but I did replace the EGR valve at 80k miles and cleaned the EGR valve at 160k miles due to soot clogging the valve. The symptom is the truck would run sluggish and blow black smoke at low rpms.
I've yet to hear of any vains getting stuck on the 6.7 PSD. My '12 requires to have the truck running in Tow/Haul mode for it to work, but I don't like to run it in this mode while driving around town.
