For the drivers that are using DEF

I used to get this about every 20-30k miles on my 2012 KWt660. Check engine came on and stayed on so normally delivered load and found a shop to work on it. The fault never said anything about the injectors just to see the manual etc. a couple of time they thought it was an ECU problem but ended up coming back on after time. Finally took it to a shop in lathrop to work on it and its been good since just had to spend a week of downtime waiting to get into the shop.. I thought it might have something to do with the fact I run team and it only seems to start a burnout when we are in traffic or coming to a stop...

 

They tell us to drain the air tanks frequently as the DEF injectors are easily plugged by the oil in the air.

 

your not talking about the amber regen light are you
when you have to do a manual regen

 

I have a 2012 Cascadia with the DD15.
Have put 60k miles on it, has 110k on it now.
Hasnt given me any issues.

I use between 6-10 gallons every 1500 to 2000 miles.
I almost never let it go below 3 bars/squares.


Last Fillup I went 2884 miles I added 8.61 Gallons.

 

Have a 2012 Pete 386 . I got it with 22 miles and about to turn 100k. I've yet to have any problems with the DEF system. Hell, the only issues I have had at all was a axle flange leak and frayed wire on the TK APU.

 

I like the 386. So does it only have duel stacks on the cab (like a 379) if you don't get side fairings?
also, are these new engines any good with DEF? Do you still regen with def? I hear its the 07-09 engines are the real ###### ones cuz they used EGR

 

just curious about def fuel in general... are there different grades? stupid question i know, but it seems if i fill my def tank with swifts def fuel, i get crappy miles out of that tank, i do find that if i use sap bros. def fuel i seem to get better miles with the same weight of loads... i try not to fill my def at swift yards as they take the fuel cost out of yer maint. acct. and again i get crappy miles.
