Engine Wear

[GoodmanS]

Didn't know where to stick this, but i'll try here



What is the main cause of wear in these engines? What causes it and what are good means of preventing it?



For explanation i am thinking is it at startup, high rpms, dirty oil, etc? I know these engines don't wear much, but I would like to keep it a long time.



I have a gen 24v, but I assume the issues are same for all of the engines.

Seriously? The modifications that we do to them drastically shorten their lifespan.



You want it to last a long time? Don't BOMB it.



Advanced injection timing. Giant injector tips (Which is a form of timing advance). Massive amounts of fuel. Outrageous heat cycles. Staged turbochargers off of linehaul commercial tractors pushing 50 to 100 psi of boost into our intakes.



BOMBers aren't interested in longevity.



But if you are... . the Cummins is THE world champ in longevity, mileage and low wear. There is a High Mileage Club. The qualification to gain entry? A Cummins with a million miles on it.

A mechanic many years ago told me dirt (dirty oil) kills engines. Change oil and filter every 3 thousand ( held 4 - 5 quarts of oil). I usually change the Mule's oil/filter every 6 thousand unless I have been workin it hard.

If you don't use your truck often dry "start ups" would cause a lot of wear.

any way to prevent start up wear after sitting? I've heard people dropping oil into gassers through spark plug hole but that doesn't exactly apply here

Dry start ups are over come buy , preoiler systems , some exotic oils , but after start up , the big wear is dirt , so a solution for me is the dual by pass filter set up , Amsoil is my brand , then also Amsoil syn. oil .

Biggest wear saver on startups... .



Never ever race a just started engine.



Always start it at the lowest RPM at which it will smoothly rotate.



The new thought has been since the great fuel shortage in 73 that you should start moving the vehicle right away,,just be easy on it. I say hogwash,, I never drive a cold engine no matter how easy I can be on it.



Use a good hi quality oil designated for Diesel. Many on this site use Amsoil. I am a Delo user. Have used Delvac while living in the Midwest because Delo was harder to get. Both are excellent as I am sure Amsoil is.



Make sure the Aircleaner is kept clean. Always make sure no leaks in the air intake. I completely destroyed an engine onetime cause there was a pinhole in the input stream.



Milage on oil changes is less important than other factors. If you are putting a lot of miles on it in a short time that is a different problem than if you are a low milage puteroner. In my opinion if you are a real short miler, the oil should be changed twice a year regardless.

I suggest running a top quality, full synthetic engine oil. Personally I highly recommend AMSOIL AME 15W40 HD Marine and Diesel Synthetic. Also run a top quality oil filter, I prefer Donaldson Endurance Nanofiber oil filters. Fleetguard Stratopores are also very good. The low cold pour point of a good synthetic oil will help in cooler weather. AME has a cold pour point of -44 degrees F. Meaning that it flows much better when cold than a conventional 15W40. This means it will pump easier, flow through your filter better, and oil pressure will come up quicker on cold starts. That saves engine wear.
