Ecodiesel

Though not an eco diesel, I have an 08 Cummins with the dpf, and the variable vane turbo. The dpf plugged once when it was fairly new, because I let it idle like one would do with any older diesel. I'm not a fan of running a diesel cold. Since it was fixed, it hasn't given any trouble, but I do keep my eye on it. As I understand (chime in here, Doc), if you haul a bunch and drive the sheeeeeeiiiiiit out of it, you're going to have minimal problems. If you drive it in town and don't pull, you're rolling the dice. That being said, I'm happy to be pulling 10K+ pounds several times a week.
The more you work it, the longer it will last. In fact, I mentioned that in my first post about the VGT vanes. They need to be flexed, often, to keep them clear. The DPF clogs more slowly--it will still clog, for sure--when working the truck as the EGT stays higher. When UPS first got their DPF-equipped trucks, they sent out a memo to drivers that in essence said, "When you're done with your route, beat on it." You'll also notice UPS trucks have automatic shutoff on their engines now.
 
Probably not, they don't have to deal with the EPA. :(
European emissions standards are getting to be every bit as stringent as the U.S. The EU controls much of that, rather than individual countries' governments. There aren't many "Europe spec" packages left other than in the medium and heavy duty truck world... and those are getting stricter as well.
 
Doc, what's the word on using the exhaust brake for non towing? I tend to turn mine on to slow down unloaded from highway speeds, simply to extend the life of the brakes. Is it worth it?
 
Absolutely. It keeps the vanes moving. On cold mornings, it's also great for getting the truck warm more quickly. On brutally-cold mornings, it's great fun to listen to the compressor and exhaust brake fight it out. :D
 
What's the big deal with ulsd? I've had no trouble. Does dumping a little 2 cycle oil in the fuel help? I would think it would.
 
You haven't had any trouble, nor would I expect you to have had any yet. You don't put 3,000 hours or 350,000 miles a year on your engine, which doesn't qualify in my book as an "old" diesel anyhow. I was thinking more along the lines of 2-stroke Detroit era engines, though not those in particular (yes, I know the 2-stroke Detroits were built into the '90s, but they weren't in common road usage by then).

I remember the 2-cycle oil suggestion being the subject of some debate at the shop, though not knowing I didn't really get involved with the conversation. It seemed to me that it would help, but for some reason I don't think Steve thought it was a good plan. The specific example I recall was a customer with a brandy-new 2015 Beetle who had 500 gallons of home heating oil he seemed to think he could somehow use in his car (for having a new car, he's a notoriously cheap sumbitch). He was inquiring about various lubricity additives including 2-stroke oil, and Steve of course laughingly told him, "Oh, yeah... go ahead! I have no idea how much you'd add, but just dump in a ton of it and I'm sure you'll be fine. What could possibly go wrong?!" Of course, with a DPF, DEF, etc. on that car it might have swayed his response as far as using it, but for whatever reason I don't think Steve's opinion is that 2-stroke oil is an even-remotely-acceptable replacement for good ol' sulfur. Why that might be, I won't even hazard a guess.
 
wait see now ya got me curious as to what "should" be added for an OLD diesel...specificly a 2stroke detroit

course that said i ran about 600gal of heating oil thru the 2001 f350..its mpg JUMPED 10pts
 
With my older (pre 98) diesels, I used to run a quart of atf in the fuel every 1500 miles or so, and mileage would go up some, but in the newer high pressure injection systems, it seems like a very bad idea. I can't imagine 2 stroke oil to be a better solution.
 
Mine probably should be considered an old diesel. It's a '98 and is mechanically injected.
