Re: Eco Diesel & Short Trips

Agree with BobT and most of the others here. My normal commute is less than 5 miles. No problems attributed to that short commute. Just don't punch the pedal until your engine is fully warmed up, which on my normal commute I never do.

I do take it on an occasional longer drive about once a week, because I love this rig and also enjoy the occasional drive.

Also, trucks are diesel because of torque. And torque is what makes our CRDs great!

Re: Eco Diesel & Short Trips

Thanks for all the responses. A typical day is 15-20 minutes to the Y & 40-45 to work mostly 55 mph. I was mostly concerned about running errands on weekends & it sounds like that won't be a major issue. Purchasing it for towing a 5500 lb trailer 6-8 times a year.

Thanks again for the feedback.

Re: Eco Diesel & Short Trips

Our Ecodiesel is used for shorter trips but we have at least 2x a week it has to go on a moderate distance drive over 45 mph the whole time. 1-2x a month it is used to tow an enclosed trailer so it gets a great workout on that. I also had a CRD before this one and it didn't have any problems with this kind of use as well.

If my commute and most of my driving was < 10-15 miles distance in city traffice I'd highly consider an electric car as those excel in low speed / frequent stopping environments and if you don't trek too far from home you always can plug it in when you get back. Then when I'd need to travel out of town - just rent a cheap economy car for the day(s). Heck you still get a Fed tax credit for buying an EV. Just food for thought (won't work for me as live in rural area).

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.
You will not have problems. We have owned diesels for over 10 yrs and predominantly do 5 minute trips, and we have never had problems.

Re: Eco Diesel & Short Trips

The diesel "cool down" recommended in the owner's manual is for heavy load driving....one where extracting power from the engine requires lots of boost from the turbocharger. The cool down is for the bearings in the turbocharger...moving oil past them wicks away heat....otherwise, the bearings can "coke" the oil which then fouls up the bearings which can then destroy the turbocharger.

Under normal driving, it's not a factor...and on the highway (without towing anything), the loads are minimal.

Agreed! If you are really worring or intend to race, there are after-market decives knows as "turbo timers". These keep the engine running for a certain period of time after shutdown to let the turbo cool off. A bit OTT if you ask me.

Re: Eco Diesel &amp; Short Trips

I watch the oil temp when towing, and try to let it get back to 100C or close prior to shut down. The gauge is right there on the dash if you want to look at it. It's rarely an issue around town unless you do a hot lap through your neighbourhood on the way home.

Cheers,
Steve

Hey! *Real* obsessives monitor the EGT and cat temps in order to decide if the turbo is cooled!

In all seriousness, I do recommend getting an inexpensive OBD II Bluetooth adapter and the Torque app (or iOS equivalent). Not only can you clear codes, see regens in action, etc, but you can also see for yourself that the turbo is cooled off simply by driving the distance it takes to get home from the interstate offramp.

I used to be all wound up about the EcoDiesel but after seeing the data myself (regens, turbo temps, Blackstone UOA data) I've really come around to the belief that these machines don't need special treatment.

Well, no special treatment beyond needing engine oil and filters made from virgin unicorn tears and the DEF injector skid plate, that is.
