From my personal experiences, yes, diesel engines typically last longer. as previously stated, it all boils down to maintenance, but i have personally seen several diesels (not including semi rigs) that have reached 500k plus, including a work truck that my dad had. it was a 85 ford f250 diesel (international diesel not a powerjoke) and it died around 485,000. our 06 DMAX is around 125 and still running strong - the only thing we've replaced so far is a set of brake pads and air filters.

Diesel maintenance and repairs isn't for the feeble or cheap. Certain components wear out, it is just considered normal. Injector pumps can cost $1500 to rebuild and as much as $3500 new.

Nearly every piece or component is twice the price then it would be for a gas motor.

The only reason I have mine is I have lots of buddies and connections for the 6.2L. I can generally find whatever I need really cheap. Besides, I love the look on peoples face when I tell them I can go 1600 miles on my 50 Gallon tank. Mine isn't remotely fast, and it doesn't pull hard at all. It runs a 3.42 gear, OD trans, and taller then stock tires. It is a trade off I am willing to take.

Im a truck driver and most of are trucks go from 700k to 1.200k on the stock engine, but a semi runs 1400 to 1500 rpm down the hiway and most diesels in the pickup are closer to 2k and rev to 3500rpm so they dont seem to run that long. however the diesel boys out here give me crap that the diesels run longer but i can buy a low milage 5.3 for the price of new fuel injectors for a dmax. i took a 5.3 apart with 220k and the crank bearings still had cross hatchs in them and the rings looked new, all depends on how you take care of them.

Me and my brother work for my dad who owns a trucking company. My dad used to drive a KW with an N-14 cummins and he put on 1.2 million miles on that engine before he rebuilt it.. We also had a KW with a 12.7L 60 series detoit that put on right about the 1 million mark... From what i've seen, yes the diesels last longer. If you think about it diesel fuel is not near as dry as gas. Its almost like oil, and having that on your upper cylinder, its just not gunna wear near as much.

Also my brother in law's dad had an 89 chevy 350 w/5 speed that put on well over 300k with original engine and trans...

The "Powerjoke" is a international too


I believe it has more to do with the piston coolers, and oil cooler combined with the low rpm of the engine that makes the old non-egr pre tier 4 engines last. Throw on all that emissions crap, you now have a engine that will be thrown away long before the short block is worn due to the cost of the components to keep it running....

The million mile diesel engines are now long gone thanks to the EPA....

Thanks for all the replys.

the 6.0 wasn't. all of the other PowerStrokes are.03-07 are the model years to avoid.
that being said, look at the DMAX, the cummins, and anything 6.4 or 7.3 powerstroke.

Sorry, but the 6.0 was INTERNATIONAL.... Ask me how I know....

Durmaxes usually dont last as long as gas engines....They are the weakest internal diesel when comparing them to Dodge and Ford.

In order from weakest built to best built
1)Duramax
2)Powerstroke
3) Cummins

We have had several Cummins go over 1 million miles and I have seen 3 Dmax blow with less than 200k miles.

Maintenance aside, diesels operate at a lower rpm. A lower rpm=slower piston speed=longer lasting.
