That sounds like a legitimate reason to use one. I wouldn't hesitate either if I was driving from Texas to the Great White North in winter conditions.

I had a 16 mile freeway commute and that was not enough to keep the DPF happy. It's just a very badly engineered bad idea. All you can do is limp it along as long as possible until out of warranty then remedy it properly, IMO.

The only issue I see is there is no way to know its status. If they had provided some kind of display to tell the driver where it currently was in relation to dpf regen status and the ability to start a regen early or delay one for some short time, things would be much better. I track mine using the vagdpf app (no longer supported) and have had no issues so far. Without the app though it is hit or miss unless you pay very close attention. Torque app has made some headway in monitoring the regens as well. We will see. The process works well you just don't have a clue about anything and it is kind of critical you do unless you are 70% highway or more.

Yep, basically someone decided that diesels with DPF are "for highway use only" and engineered the DPF's accordingly. So utterly stupid--and such a simple thing, you wonder how they overlooked plain common sense. They should have an interactive that lets you know something like: "I need 15 uninterrupted minutes for regen soon, please authorize when you are ready." Then the driver could defer it, but the "xx" minute time would just grow. It would decrease DPF early deaths more than any other thing, IMO.

For those interested in the view from the other side of the Atlantic you might want to look at site (in English) such as this one where there is much bigger and experienced pool of CR owners with DPF and SCR (as compared to North America):

http://www.ukpassats.co.uk/phpbb/index.php

For the OP might want to research also the experience of TDI owners in Europe with DPF/SCR using ashless two stroke oil.

I picked up my Ram 1500 Ecodiesel yesterday. According to the owners manual, it will tell me when I need a regen and also when the truck is in the process. I put about 20 miles on it for the test drive and then 100 coming home. So I’m sitting at about 135. Too soon for a regen.

Search here and in Google using keywords "cerium dpf" and "eolys". These are additives that reduce the activation temperature for the DPF. Note however that VW doesn't sanction the use of any such additives, and there are questions and concerns about heavy rare earth metal - which Ce is - mining and accumulation in the environment.

Edit: When all is said, there's nothing better than proper maintenance and driving schedule that allows the DPF regeneration always to complete. Driving short distances is death for Diesels, even pre-DPF ones. Sorry to say, but choosing a right car for the job is a good principle to follow, and if your usage habits are biased toward short trips, it would be better just to get non-Diesel car.

No additives needed with any type of fuel purchased in California, though Propel is the best stuff you can get!

KJclow - nice truck! You need to add it to your list of Cars/TDI's

Thanks for the reminder about Cerium. I realize that I posted on this topic a while back with some more background information and usage in Europe:

http://forums.tdiclub.com/showthread.php?t=456424

Perhaps the fact that products such as this one are not available in the US is because they contain Cerium and are not allowed by the EPA.

You don't need a highway run, just an app with your smart phone and a plug in obd bluetooth dongle telling you when the regens happen and let it finish before shutting down. City driving is fine, it just takes longer as each deceleration lowers the temps, constant driving is better but speed has nothing to do with it, just constant driving at any speed. The event happens every 500ish miles or depending on soot load (there are other factors but the distance and loading ones are the prime factors). I find on rural roads it takes a good 12 miles to run through a regen-a good 15 minutes of driving in those roads. It starts off within a half mile of driving in warmer temps...

Is Propel HPR acceptable under VW's warranty restrictions regarding biodiesel?

Power Service Diesel Fuel Supplement (aka the white bottle) is the O negative of diesel fuel additives. You can find it anywhere and it works fine in any application any time of the year. If you don't want to think or hunt or pay an exotic price, just use PS white.

Show me proof that these additives (any of them) do substantially any more to reduce regens. Regen management is the real key here not additives. Of the two you mentioned only Diesel Extreme mentions "up to" 50% reduction in regens, and then nothing more mentioned in the literature available on its page. It talks all around about cleaning and detergents, but how dirty can a 2015 with 5k miles be? I doubt there is much help there to be found. Their other claim is improving the fuel, but the OP is in California with supposedly some of the best mandated diesel fuel in the US. Fuel additives can only improve so much especially if the fuel is already top notch. I find little to be gained here either.

I have nothing against additives where and when needed but for this purpose/post they seem useless. Some people use them all the time and many others never use them at all. Both without issues for the most part. I have tried many kinds in the past and saw no benefit from them without scientific testing being done.
