Eco Diesel & Short Trips

Re: Eco Diesel & Short Trips

If your main driving habits mostly consist of these 5-10min short trips, than a diesel is not for you. The new diesels need highway miles for correct operation. A diesel engine is designed to run at operating temperature for extended periods of time. This is why over the road trucks are all diesels. I'm sorry my friend if you bought a diesel to make mostly short trips, than I'm going to guess you will have problems with your new purchase. Sorry.

Re: Eco Diesel & Short Trips

First, are you mainly doing 5 - 10 minutes trips only?

Re: Eco Diesel & Short Trips

It'll do fine with short trips as long as you occasionally (at least once per tank of diesel) take a trip at highway speeds (40MPH or more) for 30 or more minutes. This allows the DPF to burn out the soot (regen cycle).

The only other thing to watch out for is letting it idle 30 seconds or so before shutting it off from city driving. 90 seconds after highway driving. This lets the turbo and exhaust cool down and helps avoid heat related damage. This is in the manual supplement for the ecodiesel.

We have a 2008 Grand Cherokee with the Mercedes 3.0 EcoDiesel. We bought it new in the fall of 2007 and drive it primarily short trips for the past 7 years. I would estimate we average two 10 to 15 minute trips every day on 35 mph streets plus a 60 mile trip every few months on the highway and we’ve had zero trouble with the engine and exhaust system.

Both gasoline and diesels like longer trips, but I’m not going to start driving long distances to make my car happy. Time will tell if the VM 3.0 EcoDiesel will hold up as well as the Mercedes 3.0 EcoDiesel in my 2007, but I think it will.

Driving an additional 30 to 40 miles a day to avoid the short trip abuse on a car isn’t free either. If it cost me $5 per day to avoid the short trips, that adds up to quite a bit over 7 years… $9100 at $25 per week over 7 years. I doubt any repair that short trips cause will come close to that much.

So, relax and enjoy the fuel savings the short trips and the mpg of the diesel.

Don't listen to people who say this is untenable. This is how I use my EcoDiesel: almost entirely limited to 5 minute trips, in-town. Never a problem, and unlike some other members who drive their EcoDiesels more "normally" with longer trips and so forth, I do not see active regen messages despite not going on the highway. I have encountered zero problems in over a year of doing this.

Don't expect to get better mileage than a gas V-8 with this usage pattern, though. In the winter, I average 15 to 18 L/100 km (i.e. 13 to 15 mpg) on dry pavement. Worse if there's snow. You just learn to ignore it. You still only have to fill up once a month.

Don't go out of your way to coddle the vehicle, either. There's no need to take it out on the highway unless you're going there anyway or if your EVIC "regen required" message pops up. Mine never has.

If you're still worried because of what others have been saying, ask them how long they have had their EcoDiesels and what problems they have personally experienced using it this way.

What he said. I do lots of short trips in mine. Its fine. You get the best efficiency doing long runs when the engine is at full operating temp, but it isn't going to be a problem other than as suggested, you need to let it run once and a while for the regen of the dpf.

I do an hour trip on the highway once a fortnight or so, not because I have to, but because I love driving this car.

Yes, there have been reports in the past that you get a message during a regen, but most recent experience is no message. I've never seen one on mine. Some of the oz owners have been using OBD scanners to monitor their dpf level and when it drops (a regen in progress) there is no message on the evic.

It also seems that if the filter full % gets high enough, it will active regen even in slow traffic. Or atleast should do.

That is correct. All EcoDiesels have plenty of regen cycles occurring silently. What I *don't* encounter is the emergency regen warning messages (the ones that tell you to "Drive at Highway Speed"). Just to restate: normally the only way to be able to tell the Jeep is regenning is via OBDII scanner monitoring Cat or DPF temps.

Follow your EVIC instructions. If a regen message pops up, obey it. Otherwise, don't worry about it because the system is happy and is taking care of itself without you needing to mother it.

Ever heard the adage "No news is good news"? Yes, that applies to regens.

Re: Eco Diesel & Short Trips

Yes, well in Oz we've had so many failure to regen problems that there is a lot of interest in being able to monitor that the system is working correctly. BUT it looks like they have an update that is going to fix it, so yay! Looks to be an export model thing only, so no impact on the US diesel.

Yes, it's strange that you gents have that issue and there are zero reports of similar problems in the North American model. We, on the other hand, have been saddled with SCR... and all the brittle injectorness that entails.

The same goes for gasoline engines. About half the cars in Europe are diesel and Europeans are not known for driving long distances. Trucks are diesel because diesels are more efficient, more torquy and industrial/commercial diesel is usually bought very cheaply on contract.
