No.

 

I agree NO.

 

Comparing Apples to Oranges....No.

 

No .....

 

The ED can have good longevity as seen by my motor but the answer to your question is no. The Cummins is more of a HD industrial design and is even generally considered to have a better expected longevity at least between refreshes than the Duramax & Powerstroke. And you see more of them out on the truck routes doing the big work than anything else. Question might be if properly maintained not abused and with a little luck does 7 to 10k hours run time or 350 to 500k miles work for you? Not saying you should expect that but I believe thats what it is reasonably capable of. Just my opinion from what I have seen.

 

How many miles you have on your truck, Vern? Just curious. I've had mine since May 14th, and already have over 8k miles on it. I drive 90 miles (45 each way) to work and on the weekends I do another 130 towing a boat to go fishing.

Until I get transferred to the facility 9 miles from home, the commute will be 90. And until the water cools off and the fish stop biting... I'm towing my boat to San Diego. I'm staying optimistic.

 

Not normally

 

For absolute longevity I would have to agree.....NO.

 

As a family vehicle used for commuting to work and occasionally towing the family travel trailer why not? I say Yes.

 

Why not? I say because the catastrophic failure rate for the Ecodiesel is likely 1000% greater than that of the CTD.

 

...maybe...depends...

 

Are we allowed to add the 7.3 into the question?

 

455,000 but at 371,500 she pushed out a head gasket. Bearings later showed to be done also. Both probably in part to my errors as I mistakenly let the coolant get low a couple times over many miles before I figured out the system only let the degas bottle get so low. This likely lead to heat spots killing of my water pump & radiator at 350k and later with many hair line heat cracks in the heads and pushing out a head gasket. I also ran past 10k on oil filters that were only warranted for 10k. Once I had an oil filter collapse and when the motor came out of the truck it had another that had collapsed. So learning from my mistakes suggests that it could have done better and I share it because I want everyone to do better than I have. One interesting thing to me is that the computer or whatever kept the motor running smooth would start easy didn't show significant loss of power or mileage up to the last day I drove it. Maybe that is a two edge sword but I have owned and driven stuff in the past where you knew that motor was worn and heading south. Some of that goes back to 70s cars but it just still impresses me how far computer controls and automotive stuff in general has advanced.

 

shawclan We like talking diesel motors and trucks here. Sure why not. Especially if it is in relationship to OPs discussion of EDs Cummins & longevity.

 

The premise of the question is fair but loaded based on one's expectations, experiences, and perceptions. The answer is an obvious NO.. This naturally leads to another question....how do the 2 engines compare against their own kind?

Seems to me the current Cummins 6.7 is this generation's version of the old world Navistar T444E engine....or Power Stroke 7.3L as most know it. I still drive one and the 7.3 still could be the most cost effective hauling platform on the road.

When I see 'Hot Shots' on the road seems the majority is CTD and not Ford's 6.7 or Duramax. Ram finally built a great truck and excellent transmission options around the stellar Cummins power-plant. Previous generations were great engines with a poor transmission and/or front end around it.

How would the VW/Audi 3.0, BMW 3.0, and/or MB BluTec 3.0 do in a Ram 1/2 ton truck pulling TTs across America?

That is a fair comparison to ponder and the first generation 3.0 BluTec from MB was an aluminum disaster.

 

Thanks for your opinion guys. I have a pretty much paid off 2016 laramie ecod. Considering a ctd for longivity. Yes or No answer is better then rather giving explanations why, if or but.

 

You did say answer yes or no please. Maybe we don't want to know why you are considering another motor just; in or out. If out maybe you enjoy the 5k a year you put on for.. long time.

Vern.. I have read thru most of your posts and I do appriciate you sharing your on the road experience for 500k miles. What I am really looking to do is dump the eco while it has some value and get into cummins. I drive about 50k a year. So from my math even with the fuel savings i have with eco is not worth it if the darn things are made to fail with such low mielage. So just trying to collect as much data as I can before making a decision.

 

Comparing apples to oranges. First your comparing a 3/4 ton to a half ton truck so the build and ride qualities are way different. Then there is the power plants the 6.7l Cummins is a much heavier engine than our 3l ED. The 3l was originally designed for a car by GM to go into their Cadillac in Europe before they went belly up. Then FCA transplanted into our 1/2 ton trucks. For me the ED as a highway commuting vehicle fit for my purpose and will tow within reason. Vern has shown that the ED can tow in a commercial setting.

 

I am well aware of what the eco can do or cannot do. Same goes for cummins I have had both. I think you missed my question.

 

I believe that there is no better engine (pick up truck) then the CDT. But even a CTD has an occasional failure, I owned a 2007 (last 5.9L) and the engine was replaced at 15K miles under warranty because a bad injector melted a piston. I also think that the 6.7L is a better engine and has better injectors (stainless steel) and they started putting better automatics behind them, on the downside you have the EGR system ( got rid of that on my truck).

 

First response I made was , "No".

After reading this discussion my second response is, "No".

 

No way.

 

Not really a fair comparison between EcoDiesel 3.0 and Cummins 6.7 You should ask best Diesel engine in a pickup truck for longevity vs Cummins,Which should include 6.7 Powerstroke 6.6 Dmax and any other truck Diesels? Still the answer would be Cummins 6.7 best engine by far for consumer longevity..

Cummins basically has always had and still has the Simplest Designed ,Extremely Well Engineered With a Common Sense approach applied to Diesel Engines , Very Consumer friendly ,operating /maintenance cost very efficient , Somefolks bring up fuel filters cost 80.00 for both every 15k ,IMOP a very small price to pay for preventative maintenance vs Hpfp or injectors...

All the above mentioned diesels other than Cummins have glow plugs ,aluminum heads CP4 hpfp(except new Dmax ) time will tell how new Dmax fuel system works out ?

Aftermarket parts for a Cummins 6.7 ...Turbo’s ,Injectors, Internal engine components,ect ..easy accessibility very reasonable pricing, None of the above mentioned Diesel engines can compare...

 

All the above mentioned diesels have glow plugs ,aluminum heads CP4 hpfp(except new Dmax ) time will tell how new Dmax fuel system works out ?

The CTD doesn't use glow plugs(always has been a grid heater) and it also uses a CP3 fuel pump.
Has the new DMax stopped using the CP4?

 

Crash ... Didn’t mean to misprint about other diesels and include Cummins with the others diesels, if that’s the way you interpreted it ..The new Dmax has a new fuel delivery system, I believe they dropped the cp4 pump....Along with a supposedly unbreakable factory ECU tune ...

If there is enough demand, someone will crack the ECU. Now you have me curious about this new fuel system and what pump it runs.

 

Of course a light truck/commercial grade inline-6 diesel engine should have more longevity than a light weight v6 diesel designed for a sporty luxury car! The eco produces more hp per cubic inch at 30% plus higher rpm's. So answer is NO.

 

But my answer is going to be no also. If I had a need for a Cummings, I would have bought one. I needed (wanted) a full sized truck that could tow a pop up trailer or another small trailer when needed, fit the whole family in and be comfortable, and the fuel milage is a big plus. I couldn't be happier.
Simple no.

 

If I had a need for a Cummings, I would have bought one.

A lot of people look for Cummings, wonder if anyone has ever found one yet.

 

The original question was longevity. We are still in the infancy of this motor applied to North American vehicles. I have no reason to believe this motor won’t last 300,000 miles. Fact is, I believe my truck will fall apart well before the engine quits. Yes, the failure rate is higher then standard. But until we see a pattern of failures past 100,000 miles, how can you conclude that the 3.0L VM is a short lived motor? Jury is still way out IMO....

Cummings does exists.

Go with No. Had both. Loved Both.
