Add on DPF

DPF add on's are not permitted any more. Just buy a newer truck.

 

OP: I haven't seen any good info on this site about retrofits. I've talked to some local fleets who have had decent results, & I've talked to some that had nothing but problems and wound up selling the truck within 6 months of retrofitting...

Example decent result: USF Redaway on their linehaul trucks (very little idling, mostly highway)

Example terrible results: Port drayage trucks (very little freeway, lots of stop & go, lots of idling)

Wrong. The rules are here: http://www.arb.ca.gov/msprog/truckstop/truckstop.htm

 

I wouldn't add one on ... I'd keep the older truck running outside of Cali ... If you need to go there with any regularity I'd buy something new ... Retrofitting an engine that was never designed to run with a dpf is a good way to kill it ... Remember the first round of dpf trucks? They were designed to work with one and they all failed miserably ... At least with a new truck you have warranty and most of them seem to run ok, most of the time ...

 

on the radio, it was a disaster at first. but more and more people are starting to claim good results and mileage.

it's a crapshoot still though,

 

I have just done a retrofit through a reliable CARB approved installer. It set me back quite I bit. It's all about the install. If install correctly there will be no issues long as you follow the maintenance. I have noticed absolutely NO difference in performance except that my truck is quietier. I went from straight stacks to DPF. Trucks sounds like a new truck. I missed the sound of the straight pipes already but it is what it is. I have seen several retrofit installer and to my disapointment felt sorry for the owners. They hack the utility box on the passenger side step and the fliter stands out like a sore thump. My install in the other hand, the utility box was completely remove and a new fabricated one that look identical(a little bigger) was reinstall with the filter inside and the inlet and outlet facing under the carriage. Now to the OP, is it worth it you say ?, To me it was was either a 2010 truck or newer or the filter, To start of with, I see NEW trucks all day long broke down on the side of the rode cuz of the emissions stuff in them, that cost more money due to down time, tow truck, and shop repair plus your new truck payment, due the math. I am fully satisfy that i went with the retrofit and that I am not stuck with the newer truck headaches that my buddies have ran into. All have said they wish that they would of done the retrofit.

Well, they changed it again. Previously, if you didn't have a DPF retrofitted by a certain date, you could not claim an exemption and register your vehicle to run in California. What a headache.
