rbertalotto Posted December 25, 2019 Report Share Posted December 25, 2019 Quick question......Been watching a few videos on the RAM 1500 with 3.0 ECO DIESEL and Ford with the small POWER STROKE Both of these trucks get 25-30 mpg when not towing When towing 7000 pound trailer they get 11-13 MPG as witnessed by a number of testing videos on youtube It seems to me these engines are blowing their brains out towing. Going up hills they are doing upwards of 3500 RPM Huge difference in fuel consumption...... In comparison, My 2006 RAM 2500 with 5.9 Diesel would get 18mpg non-towing and 13mpg towing.....And my new RAM 2500 with 6.4L Hemi gas motors does 18mpg non-towing and 11 mpg towing (both towing same trailer @ 7000 pounds) What say you.....Will these little diesels last with that type of use?

Kirk W Posted December 25, 2019 Report Share Posted December 25, 2019 (edited) Since my 2003,Dodge/Cummins is paid for and running strong, I doubt I'll be buying one of them anytime soon but I have read some interesting reviews.

edatlanta Posted December 25, 2019 Report Share Posted December 25, 2019 My 2006 has been paid for for a long time now and I'm definitely not interested in a new truck. It has 205,000 on the ODO and is still going strong. Yes, some normal wear and tear items have been replaced, but all is good and a lot cheaper to maintain than buy a new one for $60,000+. I get 12 mpg =/- 0.5 towing my 5th wheel and 19'ish non-towing. It was exactly the same when it was brand new. Happy Fulltimer here and Merry Christmas to all here.

Ray,IN Posted December 25, 2019 Report Share Posted December 25, 2019 It is logical to assume ANY reciprocating engine will wear out faster when operating at maximum capacity vs lighter usage.

bobsallyh Posted December 25, 2019 Report Share Posted December 25, 2019 I've watched these ever since they came on the market. My opinion then and still now is that they are for somebody who thinks they need a diesel but it will always be a grocery-getter and day tripping pickup. If you want a diesel for towing put "your big boy pants on". It will be interesting to see if in the future these small diesels will have the longevity of the old Datsun and VW diesels.

Jaydrvr Posted December 25, 2019 Report Share Posted December 25, 2019 The MB Sprinter is all about their small diesel. It seems to enjoy a good reputation, but I have no idea if that means it's reliable long term. Curious.. Quote Link to comment Share on other sites More sharing options...

I guess it depends on your definition of truck. 3.0 liter diesel, 15,250 GVW, with up to 5,000 lbs. tow capacity. Seems to be in the general vicinity for comparison purposes. Seems to me the question was about the longevity of smaller diesel engines, so not sure how relevant the truck part is.

Pappy Yokum Posted December 26, 2019 Report Share Posted December 26, 2019 Will they last? - Only time will tell... '05 Dodge (Ram 1T 5.9 CTD here) . *If* I were to buy a new pickup, no matter which brand - it would be a gasser - no def (& related system) req'd - or desired! *If *I wanted a heavier 5th than I have now - AND I thought the large displacement gas engines weren't capable (or I needed a dually) - - I would bite the def bullet, BUT you would find me on the HDT forum! ~ Quote Link to comment Share on other sites More sharing options...

And we all know where that line of logic leads.🤣 Seriously, no one class of truck, or fuel type for that matter, will be best for all. I'm glad we have choices. I have a F-150 for my work/ play truck. It has the Eco-Boost, and it fits my needs perfectly. But it also cost over double what I paid for the HDT, which only gets around 5k mi/per year.

Dapperdan Posted December 27, 2019 Report Share Posted December 27, 2019 IMHO a small diesel will take more "abuse" than a gasser of comparable size/displacement, it will for positive have way more torque than gas. I believe the biggest draw back is the up-charge for the diesel compared to the gas, hard to justify the extra cost initially AND the higher cost of diesel fuel. I just LOVE my Cummins Turbo 6.7! The power and the torque are all I could ask for. Dan Quote Link to comment Share on other sites More sharing options...

rfcn2 Posted January 5, 2020 Report Share Posted January 5, 2020 Yup. Some things goes for diesels in motorhomes. We have a 12 liter Caterpillar diesel and we get about 7-8mpg. Several of our RV friends have smaller lighter rigs with smaller motors. They get about the same mpg as we do. One of our friends has a much smaller class A with a 5.9 and that gets a bit better mpg. We have one friend who has a 40' (ours is 42') and the motor is too small. His miles per gallon are the same as ours and he overheats on long uphills. You have to work smaller motors so hard they don't save fuel.

Lou Schneider Posted January 5, 2020 Report Share Posted January 5, 2020 (edited) Any loaded engine will be most efficient at it's peak torque RPM. If you have to run it faster than that to make enough power it's wasting fuel. The only exception is a lightly loaded gas engine because of the throttle valve restriction on the air intake. In this case, running it slower than the peak torque speed when the throttle is mostly closed may deliver better mileage because the engine isn't sucking as hard (and wasting power) to get air past the throttle plate. But on a diesel engine or on a heavily loaded gas engine, the most efficient operating speed will be around the torque peak.
