QL4 interval on this engine is 21000 hours. Seen one with 51000 hours, only replaced turbochargers an heads. MTU is one of the best engines with proper maintenance. No need for special addictive in the oil.
I've been working on MTU engines for 15 years and seen 4000 engines run till 30,000 before major overhaul, and at that many hours the liners/pistons/bearings look like new still... no additives used.
Yeah been to the training center for S4000 tier4 overhaul. Great setup , lots of mtu engines to look at , instructors great. I had Wolfgang in the past for ECU7 training , he’s very knowledgeable. For overhaul I had Greg Mowbray, they are all good teachers. All the best tools and specialty tools there to use. Highly recommend going if you get a chance.
I learned my lesson about German quality. They overcomplicate and add so many extra parts to things. It just makes a lot of failure points. I like the Japanese stuff. They keep it simple I own 2 Honda's and they seem to last forever. and I do use shaeffers oil in them
bauerle2009 recommended overhaul for this engine is 10K hrs. They ran it twice that long. They don’t wait for them to blow before they overhaul them. Many fleet & industrial applications automatically overhaul equipment at given intervals regardless of how they are running.
The secret with good engine condition in MTU engines even after many operating hours is load If you don't load MTU engine enough, many problems will appear very early
