Very interesting. My first new car was a 1999 Mercedes E300 with 796,000 miles, the OM606 Diesel. The engine and transmission has never been out of the car. It has been running on Mobile 1 synthetic 10W-30. It still runs well. Currently we are replacing the fuel pump because the original one developed a crack and started leaking oil. The goal is to crack a million miles.

[@johnantonopoulous6381]

I grew up in my dad's shop which was a Mercedes indy shop and the best thing you can do on for that engine is swap you filter halfway through the oil change interval. if you read the old Mercedes maintenance manual it even recommends it. The m103/m104/om606 blocks are one of the best engine blocks ever made. I got rid of my w202 after 350k just because of all the other aging car issue that I did not want to deal with it anymore for a daily driver but the guy I sold it to still drives it at 450k miles.

[@user-oi8tg3dq7t]

The 1999 E300 has a system that tells you when to change the oil. Since this car runs on the highway, the oil change interval is right around 20,000. Over this time, the engine has consistently used 3 quarts of oil during this time, unless an oil leak develops. It gets driven nearly 240 miles to work, then a few days later home. It has always been idled a couple minutes before driving unless it is very cold then a few minutes longer.

My 1972 240Z Datsun had 660,535 miles on it, when we finally scrapped it in 2002. Was used as a family car, and multiple long trips. As a GM engineer, I was able to maintain it and keep it running. However at some point, common parts were no longer available for cheap, so there came a crossover, where a newer car was needed. We also had a 1975 Toyota Camry, which we finally gave away to Goodwill in 2005. It lasted another year, then the new owner trashed it because she ran it out of oil. We saw it along the road, abandoned, looked into the hood, and saw the obvious. It made me cry. Our regular family car, 1995 Honda Accord has 275K on it, and still going strong.

This engine use case is interesting because the guy obviously did regular maintenance, plus he benefitted from very long duty cycles driving campers across the country (the opposite of stop and go). In addition, he also had that 1 micron filter they mentioned at the beginning of the video. HOWEVER, he did also say in an earlier video that he did idle the truck all the time. Remember he said he would regularly sleep in the truck on long trips and idle the truck overnight, contrary to what Dave said at the <a href="#" class="seekto" data-time="975">16:15</a> mark. To me this says that excessive idling in a vacumm is indeed bad BUT if you are doing regular maintenance and running the truck for long periods at peak (non-idle) engine temps, you can still prevent a lot of engine wear and carbon build up.

Generally when calculating life time of bearings there is a 10% failure rate used. Reason is that there are so many parts with individual tolerances. So you check the lifetime but accept failure. Benefits are less friction - after 900k mls this is no failure, it is just wear due to concept.

Dave, nettle bearings spread the load more than a bushing will, think about it you can't have a dedicated oil supply so the impact would be on just two areas of th4 lifter. The needles move around so the load isn't iin the same area every stroke. The total area covered would be less than the needles. I think they designed the lifters the best way, not the only way, but the best for a push rod engine. The best way would be with overhead cams. Push rods are for lawn mowers.

[@biz5543]

came to the comments to say this about needles vs bushings.

[@HuntsT]

This isn’t totally true. Bushings apply the load to the film of oil. Needle bearing apply the load to the needles. There is a reason pistons and main bearings are bushings and not needle. If flowing oil is available bushings are better. If flowing oil isn’t available (such as a drive shaft yoke) needle bearings are better.

Probably Synthetic Rotella 15w40. Probably changed every 5000 miles. But considering the advanced filtering system, and road traveling without stop and go, might he have gone to 10k but I doubt it. Very impressive life out of a motor especially considering how hard he worked it. I would probably guess 5000 mile changes.

[@bobr7867]

@@phil4986​​⁠In the first video with the owner and Dave’s son Miles the truck owner said he did oil analysis routinely and based on how well the oil did he started with 5000 mile changes, then 7500 and I believe he ended up going at least 10,000. But it seems the key is that the truck ran 12 hrs a day every day towing travel trailers from coast to coast. The engine was always at full operating temperature with clean oil and fuel. I have an acquaintance who also towed travel trailers with his Ram 3 liter Ecodiesel and got 462,000 miles on the first engine and over 300,000 on the second before he moved up to a Cummins. Modern diesels need to be run, little idling and longer trips. City driving and modern emissions don’t go together. Look at Dave’s video before this one “Looking at CP4 at 900,000 miles.”

Everyone wants to know about the brand of oil, but I'm more interested in the filter. Subaru developed an oil filter that I used to use called a Trasko. It's a canister filter and you replace the element. The element resembles a roll of toilet paper, but it wasn't. It also had a super fine stainless screen that would capture metal flakes. The first oil change on my Fed Ex Ground Workhorse P30 had about five flakes of metal in it; I about filled my shorts. I added Lucas at my monthly oil changes and never saw another flake.

I have marine engines. I centrifuge my oil every 50-100 hours. The centrifuge returns oil to semi transparent, almost as clear as new. Because the engines are free of sludge, the oil never gets completely black. I test the oil once or twice a year. Before I started using a centrifuge I used a bypass filter. I get 2 or 3 times the service life between overhauls than others using the same engines in the same service. The biggest difference is in the sleeve and ring wear. But my bearings also look like new. Crankshafts don't wear. I haven't ground a crank since the 1960s. Clean oil makes a huge difference. I also drain my PU and run the oil thru the centrifuge. I like having people check my oil for their expression when the dipstick has transparent oil. I'm anxious to use speed of air pistons.

As I recall, this guy was doing 10k-15k mile oil changes with a bypass and oil analysis. Is Dave’s motors going to require him to change oil at 3k as it states on their website for warranty? Dave is marveling at how clean the engine is, and at the same time telling people to cut their service interval in half. This thing was going almost double the recommended oil change interval and it’s spotless. But the guy was doing it the right way. My hang up is Dave require proof of 3,000 mile oil changes for warranty. This is proof that this policy is out dated and not friendly to the customer.

@ you aren’t wrong but that has nothing to do with the oil. It saved his CP4 pump for sure. But the bearings and pistons look awesome for an engine 1/4 the miles. His oil change interval was perfectly appropriate at more than 10,000 mile intervals. Is Dave going to honor his engine warranty at this interval or is he going to stick to the 3,000 miles as stated on their warranty page? That’s the question

[@chrispy104k]

@@mebordernoneya8484 The owner was always doing very long trips delivering stuff (he did say but I can't remember what he delivers).

Back in the day when I used to build two-stroke dirt bike motors, the lower rod bearing, and it was a needle bearing, it would always fail, & the needles would get sucked through the ports, and it would always end up chewing up the top of the piston. It would always happen on the real high horsepower KX80, CR 250, last one I did was an RM250. They would press the crank halves together, in the rod was a solid piece with needle bearing between the crank journal.

From my own experiences with needle roller bearings, I have always considered them to be superior to plain bearings. In my two-stroke motorbike engines, both brands, Yamaha and Suzuki, the top end bearings were needle roller equipped, and never failed me, Both engines didn't use pre-mix, but rather a metered oil supply via the carburettors. I have had more trouble with big end roller bearings, strangely enough, though I know why, in that single instance. I do appreciate your argument in this case, where the bearing surface receives minimal oil feed at start up, on each occasion.

Totally agree with your forensic analysis Dave, the surface bearing pressure of a thin line compared to a rectangle is probably one to two orders of magnitude lower - probably10 to 100 times lower, if bushes were installed from new, the engine would last probably +2M miles 😊

[@wickertwm]

The needle bearings experience a point load. Theoretically the surface area of the bearing on the race is zero square inches. That changes of course on the quality of manufacture, the wear on the bearing, and the tolerances. It is like a locomotive wheel. It is solid steel in a "perfect" circle, resting an a steel rail that is perfectly flat. What is the contact area....Zero square inches in theory.

[@N4HHE]

"Theoretically" the contact between pin and bushing is also zero. The difference with a larger diameter pin in pin/bushing vs needle is more area is closer with the pin, more area for oil to suspend the pin. Catch-22 is the pin/bushing must have oil else contact is made. Needle bearing can roll with less wear during low oil conditions.

[@demon1954]

Ball bearings are even worse, especially if sizes aren't perfect, because then a lot of heat will concentrate on the largest bearings and then guess what? My experience is based on the front left on a Mazda MX5 race car where I ended up replacing them as a maintenance item every 6 months, thus getting rid of the failures.

[@robertjackson7590]

The Carbon in the Ring Pack is a sign of PCV System function. If that system fails the Ring Pack will be overloaded with carbon and it all goes downhill from there. Few if anyone acknowledges or tests this system other than loosening the Filler Cap to see if it has a slight vacuum holding it down at Idle. It's as simple as hooking a Manometer to the dipstick tube at Hot/Idle. All engines should have 500K+ of service life with little to no problems, gas or diesel. Great video guys.
