Cummins K series Cat 3408 mechanical and HEUI both were good CAT 3406B and C Cummins 855, big cam to N14 select plus Detroit series 60 DDEC 4 and up

I worked in a bauxite mine for close to thirty years. We had over 90 percent Cat machines. Some Dressers with Cummings Engine and Euclid with Euclid and Cummings Engine. We planned to replace Engines at twelve thousand hours intervals. We had Cat Engines failing at nine thousand hours while Cummings Engines was still going at sixteen thousand hours .

You forgot the 3406 CAT

Best diesel engine ever : VW 1.9l TDI with 110 hp. It was used in cars, boats, MPV and from other companies, like ford, Chrysler, Mitsubishi….

I drive a 1993 Dodge Ram W350 Cummins 4x4 Dually with a Manual Transmission and this video is the reason!

My uncle worked at Cummins Diesel in the dyno department. He tested every model available, particularly the Mack Thermodyne for it's great fuel milage.

I know it's a car engine, but the mercedes 0M617 engines should be included here. It was amazingly well engineered.

Here's another vote for the IH 7.3 POWERSTROKE. I ordered my '96 F-250 and waited 13 weeks for it to be delivered. I put around 315,000 miles on it, gave it to SON and it now has over 325,000 miles. It's had 3-4 cam position sensors, couple glow plug relay's, two water pumps, a power steering pump, one set of glowplugs, we've replaced the fuel lines in the Black VALLEY of Death twice, found a few forgotten tools on the second replacement. Son brought some really good replacement fuel line home from work, I fotget the brand but it's already outlived the crap my Ford Store sold me. I hauled Dad's '51 FARMALL M home, bit over 200 miles grossing 20,000+#. 5 spd ZF with 3.55 axles and ran 60-65 the whole way. With dual fuel tanks I carried around 40+ gallons of fuel, enough for 800 miles between fuel stops. In the 325,000+ miles I only ever added ONE QUART of oil, 15W-40 Rotella. I drove over-the-road with Detroit powered trucks, I'm used to carrying 3-4 gallons of oil with me. No need with the 7.3L.

I was told by a very avid mechanic who had no personal preference or vendetta against any manufacturer, he said the dt466 was the best most reliable diesel engine ever built. He said it was the only engine built and designed for 3000 working load rpm’s and 1200 hp, yet fuel efficient and lightweight. Easily rebuildable and phenomenal longevity.

Napier Deltic was just splendid

I Drive a 1988 S1800 International Fire Truck and it still runs great all these years later.

The Volvo D13 that I owned and drove gave me Excellent Service. Crossing the scales at 72,000lbs+ it averaged 8.0mpg and never failed to start. The gripe I had was a leaking coolant over flow tank.

For the applications mentioned these are all great choices. Consider the applications for the M-B, OM (oel motor) 636 and OM615 units, both capable of many hours / miles and widely used. Thanks. Narragansett Bay

Detroit Diesel was dying because the two cycle engines (53,71, 92, 149 series) which they made could not meet emissions and were not as efficient as the four cycle engines of the competition. The 50 series wasn't a problem because is came after the 60 series. The 50 series was a 4 cylinder version of the 12.7 liter 60 series engine. It was popular in bus applications.

I have a 7.3 with almost 300 on it with 180 30 single shot injectors and 66 mm turbo and cnc performance oil pump pushing 415 hp and a 1015 foot pounds of torque

Nav star 7.3 Never let you down Had one in Australia $150000 of warranty work in five years Of road a total of 7 months in that time Included water jacket crack near engine mount leaking coolant on to the ground running 😮

The duramax isn't American it was designed and built by Isuzu in Japan

Yep I just sold my 2000 7.3 powerstroke. One helluva an engine. It was mated to the 6 speed manual. Tell you what this thing would out yank ANY truck today with its nasty "granny" gear. Unfortunately I aged out and could no longer get up into the truck as it was mounted to an F350 dually.

No mention of the Gardner LW series some of the most thermally efficient engines produced & very long serving!

All heavy duty engines are 6 cylinders. Naturally balanced engines. more bearing surface. 1 head, 1 manifold. simpler exhaust system.

Scania 770hp V8 = "Hold my beer ........"

I thought this was going to be the best diesel engines in the world not just the USA.

A few years ago I was told by a man who dismantled trucks and buses and exported the engines to Africa that he could get SIX times the price for a Gardner engine compared to any other engine

You forgot the 3406 cat and 855 cummins. You could have forgot a couple you mentioned . 2 of them were junk

On the 7.3 power stroke, I was told the dealers would give you a 30% discount on injectors and glow plugs if you bought 3 sets at a time!

The greatest diesel engine ever built was the Detroit 671 it helped us win WW2 I was a fighter my truck was equipped with a 671 for eight years it never failed us leaked a lot I remember it pumped for 46 hours and never missed a bet

Our fire department still 22 fire engines powered by a CAT 3406. All have over 100,000 mils on them and still going strong.

Oh don't forget the 903 comings because with twin turbos on it would kick out a 1000 horsepower and maybe. Some? Small. Modifications. The injectors.

cummins N14 best

No mention of the absolute ringer that was the Mack engine?¿? Or the million+ mile Guarantee of the 3406 Caterpillar 4&¼ that outpulled & out shone all the rest at the time!¡!¡! I can't take this list seriously. Also Mercedes-Benz are literally world renown for longevity & efficiency!!!!

Have a look at the Deltic.

You probably haven’t heard of the Toyota 12 HD-T Now that’s a truely beautiful engine

CAT 3406

How about a Mack E9

The 300 mack

The 60 series was designed around the technology and not the other way around. Big difference. The problem today is too much electronics and ridiculous emission standards. Dt466 format needed designed up and down to meet all market demands.

Ever heard of Hanomag D28?

D E U T Z ?????

Also forgot the 10 liter Cummins. I had 1,000,000 miles on an 250.

53 series 71series 92series dt466 isb cummins series 60...

No video on diesel engines is complete without mentioning the 1N from Toyota. Indestructible! More economical dollar for dollar than a Prius!

No mention of the magnificent range of gardner motors, when it comes to marine motors there' wast a motor made that could hold a.candle to these machines, the last one i had was the un-equeled 8L3B, 230hp @ 1150 rpm had a five and three quarter inch bore and seven and three quarters inch stroke,it was coupled to a 514 twin disc box with a 4.25 to one reduction, the complete unit weighed in excess of three and a half tons, just a crying shame they are no longer made ,

Have you heard of Perkins Engines? Used by Caterpiller

Hello, have you ever heard of Volvo or Scania? Or the metric system? Apart from maybe Caterpillar the US has not been leading in diesel engines

CAT C16-7cz!

This should be called, best American truck diesel engines. There are other Nations that make diesel engines and other applications, such as boats, ships, trains, armored vehicles, planes and cars.

The 50 and 60 series were not designed by John Deere. They are Volvo's. VED 12 and VED 11

What about SCANIA ENGINE? DS11 DS 14 V8.

04:30 Unfortunately , that’s inaccurate. The Series 50 did not precede the Series 60. The Series 50 was a four cylinder version of the Series 60. Also, Detroit’s engine program wasn’t exactly “dwindling “. Nearly every transit/coach bus in North America was Detroit Series 71/92 powered at that time. The 2 stroke simply was not going to meet the proposed stringent emissions regs ( even with the refinements that DDEC offered). That’s what lead Detroit (with John Deere’s assistance) to design a 4 stroke electronically controlled engine. Also, the 14L Series 60was not so Detroit “could focus on the larger engine market”. The displacement was increased to 14L due to emissions.

You got two right

The Duramax engine is a good motor but it has one fatal design flaw and why the design engineers did this is totally stupid and should be called on the carpet for this one. In the crankshaft where the timing gear is positioned for the camshaft the crankshaft gear is held in place by a round dowel pin not a standard rectangular key used in every engine design from the beginning. So what happens is when the dowel pin is sheared off the camshaft goes out of time and pretty much destroys the entire engine. What engine rebuilders are doing is machining the crankshaft for a standard rectangular key , problem solved.

You mean "top 5 diesel engines" in USA....so narrow point of view

The 3406 was the best Engine ever built

None of the engines in the video comes up in my top 5. Some other to consider Perkins 4.236 Volvo D100 Mercedes-Benz OM 444 Mercedes-Benz OM 352 Scania D16

Duramax has it problems

You forgot the Ts 3…..6 pistons, 3 cylinders

The 6.6 liter Duramax.... all the talk about GM, but the fact is that it's an Isuzu engine.

Does this include European or just American

What a crock, this should have included other manufacturers outside North America, MAN, Isuzu, Mercedes Benz, Hino, Gardener Mitsubishi, Duutz andVolvo, to name a few. The AI voice over is equally annoying.

My 99 7.3 Dually still runs like a top. Just had to do a water pump first time. No visible blow-by yet. I take it out on 500 mile trips every few months and do a little around town stuff and it gets 20 mpg on hwy now after the water pump change I think due to getting the heats back to normal (replaced thermostat). These motors don't like cold water temps and the fuel mileage will suffer. I have replaced the back pressure tube and sensor and I resealed the turbo and turbo pedestal o-rings. This setup is stock and even the muffler and tail pipes are original.

You should call it the best diesel engines in the USA and the USA is not famous for diesel engines.

Not a Caterpillar here? What a f'ing joke. Caterpillar built many groundbreaking long life dependable engines.

Top 5 diesel engines in US.

Can't look beyond the swedes Volvo &scania best engines end of.

cummins diesel left my country i remember very well in the70ies when diesels were introduced in europe that was something my dad bought a brand new ford transit diesel and that thing got an international ^price for smoking Came to it that in fact no meachanic could work or adjust diesel engines in my country::that profession was called a diesel specialist at that time. Diesel specialists , I have seen them coming home in the garage, always had a grey vest on an assumption of theuir skills. We shifted back to gas in our engines soon after but it was the oil crisis and costs were pretty high to drive that along all day long. We still had other diesels afterwards but my dad had become hesitant. Cost prize of a diesel was much higher too. It has last until the mid 80 ies when ford finally put a turbo on their diesels under pressure of the japanese. So pride owners of a brand new sierra drove around as if today your turbo has been blown. Still very proud. That turbo was in fact the Ford Turbo retarder, it left a voight on a Ford sierra good to roll a cigarette in I don't like diesel...at all.

Perkins 1006

Arcates? Sshhh!

Mack e9

Well, it is "Top 5 U.S. Diesel Engines of All Time".

Power stroke

Alpina m57-not bmw alpina

Europe, beats all US engines in fuel economy. Scania, Chief Engineer Engines.

Who put this list together... And what was the criteria it was based on... Looks like they were really only looking at north American sold diesels so... 5- Mack E7-400/427 4- Detroit series 60 DDEC3/4 3- Cummins N14 Celect plus 2- Cat 3406 B 1 - Cummins B/C series 5.9/8.3 This is not hard people... Based ability to get lots of work done with high hours of service.

A list of tops of all time diesels that doesn't include the Mack Thermodyne/Maxodyne engines is a total farce. And where is the Cat 3406?????

international maxforce 13 should be on here

Mercedes OM422, overbuild and so reliable that it is boring.

Can't wait for your list of best musicians of all time. Milli Vanilli and Ashlee Simpson are on it but not The Beatles or Elvis.

Gardner !

As a proud owner of a 6.0 power stroke I’m offended it was not on this list.

That is a pretty local storry, this one. Only US made….

Only usa engines

WTF BS

It’s not a best list if it doesn’t include 3406B caterpillar

Isuzu made

World best diesel engine ever is Peugeot 404. They still drive in Africa and around World

DT 466 is nothing but a money pit

Cat 3306 ? You need to do a bit more research I think.

#4 is an absolute joke.

I wouldn’t brag about Ford’s power stroke. They have two internal O-rings it cost $8000 in labor to replace them let that sink in

3,000psi of boost and 4000hp😂

this video and list is a fing joke. probably made by some desk jockey that never touched one

I only have 1 problem. 5 of those engines you put up are for less that class 8 except the 60 series. If you want to class the best diesels where is the KT?, 3408? and what was the other one? But a 13 letter shitspreader???? get real.

Typical post from America. There are many counties around the world producing Diesel engines, many of which are arguably better than some on your list. You ignorance of anything outside your boarders is astonishing, but sadly not surprising.😵😵

OMG😂 All US diesel engines… The persons that made this video clearly dont know much about diesel engine. Europe has made a ton of diffent diesel engine that outperform the US engine with ease. Diesel engine is much more used in Europe, and non is mention here….

I think this video was purposely made to gain haters! They seriously put a Durajunk in there and not the 3406 line from caterpillar. Come on 🤣

Duramax 6.6😂😂😂😂😂😂😂😂😂no diesel with a aluminum head should be on the best of list!

A 5.9 isn’t anywhere close to being a top 5 diesel engine. You needed to expand your knowledge of diesel of those 5 a DT466 is the best

The Durmax is nothing but piece of junk from the first one up until now .

Have to laugh, Cummins is thru stock holdings owned by Ford. Sick!

This must be made of some stupid AI tool...
