How many miles can one expect from a well-maintained original engine in a 1985 MB 190D?

I have routinely been able to get more than 200,000 miles on well maintained U.S. built engines but in reality, none have ever gone out on me when I've done the maintenance. I gave one of my vehicles to a friend when it had 200,000 miles on it and he said the engine was still running well at 300,000 miles. In reality, I usually sell the vehicle long before then. When I sell vehicles with high miles, they never have "blowby", always have good compression and don't use oil. High miles aren't necessarily a problem for GM and Ford engines if you use high quality lubrication and change the oil regularly. Unfortunately, I haven't had the same results with European and oriental engines, contrary to what some of the consumer magazines will tell you. European and oriental engines tend to be much less forgiving when you overheat or have some other problem. If everything is maintained perfectly, they all do ok. Many of the diesel engines have been able to get over 500,000 miles if maintained well. Good luck and take good care of your vehicle. Hello my name is Adam I'm living in the Netherlands.
