There?s a 2015 low mileage one at a Ford dealer near here,I?m just wondering if they are good engines or if they?re poison?

I've seen info about a cam timing problem, but don't know if it was resolved or when.
 
There is a good reason its at the Ford dealer I would suspect. Traded it in on a better truck/engine....FORD!
 
My dad has one and would never buy anything else again.
The first year ones had problems but after that it was resolved.
Around here they get something deleted on them or there nothing but trouble.
I think it has the pollution thing deleted. My dads was in limp mode all the time.
Got the $2500 delete done and has no issues since. 38 miles per gallon when the go on trips.
 
I know of one in my area that has been good for the owner...but he says the cost of oil changes and fuel system filters is killing him, saves on the mileage but a lost on the maintenance.
and he only gets fuel from the local staion, never from his own fuel truck for the excavators and trucks...
hope it helps

Does it still pass state inspection after the delete?
 
Wife's nephew bought one. Really happy with it, good mileage, drove nice. Then, it was recalled for a PCM update. I think it was the one that corrected a 'fudge' they were doing on emissions tests.

When it came back from that, mileage plummeted. Several dealer visits later, the dealer took it back. He got his down payment refunded and the outstanding loan balance forgiven.
 
My sister in law has one and it has been to the dealer several times for engine repair. I remember once being for headbolts being loose or either some sort of head repair. They are expensive to maintain.
 

People have to come to realize this is 2019 with Tier IV emissions and diesel fuel costing more than gasoline per gallon.
Some people still think "diesel is status".
This is not the 1990 s glory days when any diesel pickup was superior to any gasoline pickup .
The direct injection gasoline engines have high compression and operate in diesel mode most of the time .
Why did GM develop the 6.6 direct injection gas for heavy pickups and medium duty trucks . In some operating environments the gasser will cost less to operate and has less down time/loss of production than a diesel.
A diesel by design operates best in HD applications at full load and at max rated rpm for weeks or months at a time . Fully warmed up and burning clean.
A gasser by design and the lighter fuel is more tolerant of putting around stop start operation typical of pickups, delivery vehicles and light duty highway applications .
 
A Fiat truck with an Italian diesel? I know FIAT used to stand for "Fix It Again Tony." I kind of doubt Italian engineering gets better when Fiat sticks an American brand name on it. But - who knows? I can say I have witnessed a few horror story with Italian Jeep diesels.
 
my son bought one few years ago. then once just off warranty the engine seized up going down the highway. that cam thing it was. they would not warranty it. he had to get another engine from auto wreaker and install it to the tune of 10,000.00 . I said I would never buy a dodge. even the company trucks are dodge and they are always headed to the shop for work on them. I also hear that dodge cost the most to maintain also.
 
Direct inject gas engines don't operate in
"diesel mode". They are never compression
ignited, they still need spark plugs to
run. A lot of misconceptions out there
about how GDI engines operate. There are a
lot of advantages to GDI, compression
tolerance, mileage, and power. But there
are drawbacks to GDI, such as carbon
buildup on the intake valves and ports that
rob power and oil consumption on GM
engines.
 
No diesel built since 2011 is worth owning unless you own a business that can write off the repair and maintenance costs, and will be putting 400K+ on it. Out side of that, a modern diesel is not worth owning. But I'm glad people still do, I get paid to repair them. Maintenance and repair costs will eat any minor savings in fuel mileage versus a modern GDI gas engine.
 
I don?t think I will ever buy a Dodge from a Ford dealership or a Ford from a Dodge dealership. Nor a CaseIH from a JD dealership or vice versa. My thoughts are if the first owner was so disappointed in the product that they switched brands, how well do you think it will work for you?

And as others have said, nothing to gain in buying a diesel pickup now, unless you are going to crank a half million miles on its odometer. Up front cost, and maintenance tend to be higher on diesel pickup trucks, gas are now very fuel efficient, gas is cheaper than diesel.
 
After 38 years of driving Ford pickups I bought a Ram 1500 1-1/2 years ago. Only have 3600 miles on it but I Really like it. Has 5.7L Hemi. Runs like a scalded Dog! Still averages 17 mpg around town. Couple 175 mile trips we've gone on I have gotten 18 mpg at 80 mph.
My last Ford was a '96 7.3L Powerstroke, put 250,000 miles on it in 7-8 years. My usage has changed A Lot. So my truck needed to change. Would not get a diesel, especially a used one.
 
To be technical, GM did indeed build a compression-ignition gasoline engine. So did Toyota as I recall. The "diesel" gasoline engine design seems to have been dropped though.
 
I pretty much agree with all of what you stated. Diesel fuel used to be a bargain. One gallon (US gallon) of diesel had more BTUs of
energy then gasoline and cost less. Plus mechanical diesels are/were relatively simple other then the injection pumps. Now? By the
gallon, where I live - diesel is nearly always priced higher then regular gas. Modern diesel fuel has less BTU energy then it used to (but
still beats gasoline). Modern diesel no longer inherently has adequate lube for mechanical rotary injection pumps. Subsequently those of
us that still use them have to hope pump fuel has enough lube additives in it to be safe - or add our own.

As far as direct-injected gasoline engines running in "diesel" mode. Yes, GM and one Japaneses company had such engines in development but
none ever made it to the public as far as I know. Last I read, GM was in the middle of development when it went bankrupt and we tax-payers
took a huge loss to bale out the company. Correct me if I am wrong, but I do not think the new baled-out GM ever continued the "diesel"
engine that ran on gasoline. Personally I'd rather see GM pay us taxpayers back for the money that was taken.

And note - before someone tries to "correct" me. I certainly know what compression-ignition is, as well as what direct-injection is. GM
did indeed have an engine in development that did both using gasoline as a fuel.
 
JDEM, I thought those Jeep diesels were made by Peugeot, which is French. Am I wrong? I do know that Spra-Coupe used them for a VERY SHORT while, and they had a horrible reputation!

On a side note, my insurance guy used to drive Peugeot cars. He said he couldn't afford not to! Said once you bought your first one, a Peugeot dealer was the ONLY dealer that would take one on a trade!

Buick, do you know if the new 6.6L gas is a revamped 6.0L, or a ground up new design? I've heard rumors it utilizes a 6.0L base with a longer stroke, but haven't been able to verify. I have the 6.0L in my 2011 3500HD, and absolutely love it, so not sure I'd upgrade to the 6.6L if it's a major departure from the 6.0L.
 
The new 5.7 averages about 2-3 mpg better than the older ones. My son has a 2018 and it averages 18 mpg around town and around 20 or a tad over on trips. (on summer blend gas) My 2009 averages around 2-3 mpg less.
 
. I said the spark plugs are used .
Some people here for what ever reasons are thinking of a compression ignition engine , without spark plugs and operating on gasoline . That ain t what the conversation was about . I said spark plugs .

6.0 and 6.2 bore . Stroked out to 6.6L. Cast iron block. Compression lowered to operate on 87 octane . 401HP
 
Jeep diesel was a 2.8L 4 cylinder produced by VM Motori, an Italian company.


The current Dodge diesel is a 3.0 V6 produced by VM Motori.
 
Alright, are you talking recent Jeeps? I had forgotten that they built some recently. I was only thing about the diesel Jeeps of the mid 80s. Comanche, I think they called it.

I just Googled it. They used Peugeot diesels for the '86 & '87 models.
 
To be fair, the first Jeep diesel had a four-cylinder Perkins but that was in the 60s.
 
Must be an awful lot of down hills . I keep hearing how Great the new gas engine is except in the real world when the mileage is about 6 to 8 mpg less
 
18 MPG at 80 MPH? Are those Canadian gallons? My diesel truck is lucky to get 14 MPG when empty at 80 MPH (US gallons). You'd better get a patent on whatever secrets or voodoo was done to your truck.

EPA was only able to squeeze 22 MPG out of your truck at 65 MPH. Let them in on your secret.

My 1978 Toyota that also has a "hemi" has a 2.2 liter gas engine and gets 16 MPG at 75 MPH with a small RV body on it. Entire rig weighs 3800 lbs. and has a low roof to boot.
 
The USA first civilian Jeep diesel was the 1961 Jeep CJ-5. It used a Massey Ferguson Perkins four cylinder, 192 c.i. engine. (3.1 liters) 1961-1968.

The Australian CJ-10 featured a 3.3L naturally aspirated diesel I-6 sourced from Nissan, producing 90 hp and 138 lb-ft. 1981-1985

The 1985-1987 Jeep Cherokee and Comanche XJ used a Peugeot-designed 2.1L turbodiesel I-4. 85 hp and 132 lb-ft

2005-2006 2005 Jeep Liberty became available with a 2.8L inline-four manufactured by VM Motori. The engine made 160 hp and 295 lb-ft of torque, and they were EPA-rated at 19/24 mpg city/highway.

2007-2009 Grand Cherokee CRD. Powered by a Mercedes-Benz 3.0L common-rail turbo-diesel V-6, its 198 hp and 371 lb-ft

2014- ? Jeep Grand Cherokee EcoDiesel. VM Motori made in Italy, the EcoDiesel rated 240 hp and 420 lb-ft of torque with a 3.0L turbodiesel V-6.
 
" gas is cheaper than diesel" - not here. Gas DOWN from $1.59 to $ 1.44 - diesel $1.36. Got my bum to the wall.
 
Yes, lots of downhills, and lots of uphills too. Truck has the towing package, 3.92 rear gears, still runs 80 at 2000 rpm with the ZF 8-speed auto. There's a couple hills it drops a gear, still runs 80 at 2500. When I made the same trip with my '96 7.3L diesel I'd get around 16 mpg at 72-75 mph. The gas or fuel you burn going uphill cancels out all the savings you get coasting downhill.

I can't wait to hook a trailer to this Ram. It's actually rated to pull about the same as my old F-250 diesel was. My F-250 had 3.55 gears and 5-speed manual trans, so rated 16,000# gross. Either 4.10's or the auto trans got it rated 18,000#, and both got it 20,000# gross. I don't think I'll push this half ton over the 16,000# gross it's rated.

This 5.7L has variable valve timing, idles and at low speeds runs on 4 cylinders. I kinda miss my 8 ft long box on my old F-250. The Ram is a Quad-cab, shorter rear doors, my first non-regular cab truck, box is 6 ft 4 inches long. Kept my F250 for 22 years, doubt I keep the Ram that long, but 5-6 years minimum.
 
Dang where you live. I pay 2.89 for diesel here at home Close to charlotte nc. I just hauled a Bentley to Miami Fl Wednesday and paid as much as 3.15 a gallon
 
Around North East, MD gas runs about 20-30 cents cheaper than diesel. It's been that way a long time.
 
I have a 2018 F-150 with the 5.0 V8. Running it 75 MPH it consistently gets 18 MPG. If I keep it at 60-65 it will get 21. Around on short trips about 17-18. This engine was $1500 less than the large Ecoboost V6 and there is about 1MPG less. Has all the power and performance I need, and for me a diesel makes no sense.
This a 4 door with FWD.

We have a 2016 Jeep Grand Cherokee Eco diesel it has 31000 mile on it. We have alway got 26 to 30 MPG. It has not had one problem and we love it.It is a 3.0 V-6 Turbo charged diesel.

The 1985-1987 Jeep Cherokee and Comanche XJ used a Peugeot-designed 2.1L turbodiesel I-4. 85 hp and 132 lb-ft

The 2.1L I4 Turbo Diesel that was used in the Jeep Cherokee (XJ) from 1985 to 1987 and the Jeep Comanche (MJ) from 1986 to 1987 was designed and built by Renault, not Peugeot!

Hard to believe that.
Maybe price of diesel is lower than gas if your buying dyed fuel.

How much is the fine if busted for using off road fuel on the highway ?
 

Wife's truck does 24-27mpg US on the highway. On a couple of occasions under ideal conditions it has exceeded 31mpg US.
2017 GMC 1500 Max Towing Crew cab 6.5" box. 4X4 with the 420HP 6.2L .
Why would we want a Tier IV diesel ?
 
These type numbers amaze me. I have an older Toyota that has never gotten more than 21MPG. More typically 18MPG and currently with mud tires on, only 16-17MPG. That with a V6 and only ~200HP when new.
 
Thank you all for the replies,I talked to a mechanic I know,he said they are phenomenal on fuel but in his experience the emissions maintenance and repair can be very costly. We do have a hemi ram and love it and it?s decent on gas,high teens easily maybe squeak out low 20?s if your careful not to push it at all. I?ll soon be making a 1 hour each way commute 5 days a week for 8 months to attend trade school then I have no idea where I?ll be placed to do electrical work. We still have some farm equipment and buildings to maintain and 45 head of beef to look after so having a truck is important but so is fuel mileage. Having a 3rd vehicle doesn?t really make sense in our situation either so we decided on a 2wd v-6 2015 Chev Colorado. It?ll still suit our utility needs and get better mileage or at least hopefully than a half ton.

Flip over read directions??

Or is it..

First on race day!

Or keep on power stroking long after the dodge quit cummin.

Or is it the new f150 diesel getting 30 mpg on the highway?

Got 33mpg on this test...

EPA does not do mpg testing.
They provide/dictate the testing procedures to the manufactures.
They in turn may or may not actually conduct real life testing.
The EPA accepts the mpg figures submitted to them by the manufactures as being somewhat accurate.
As if the builders actually performed mpg tests based on the EPA test procedures.
