I have a 2000 Buick Park Avenue with a 3.8L series II V6. Currently it has 237,000 miles and runs perfect. I still average 23-26 MPG. I keep up the maintenance and expect 300K unless something catastrophic happens.
Any engine will last several hundred thousand miles given proper care (tune ups, oil changes, etc).
150,000 miles on average with regular recommended maintenance.
Mine made it just over 80,000 when the engine blew
Modern American made engines can run several hundred thousand miles if properly maintained. Follow the manufacturers specifications and use high quality lubricants, coolants and replacement components and your Buick and other American cars will last a long time.
It has a timing chain that should last the life of the engine.
450,000 miles on the original engine.
If all maintenance is performed on this engine according to the owners manual then you can expect this engine to last at least 200,000 miles or more. That is assuming the engine is not abused and is driven normally.
2.456 miles
The "Dodge" diesel is actually a Cummins heavy truck engine. With proper maintenance, it should last about 250,000 miles. The injectors will need replacing every 100,000 miles. I would say 500,000 is average for the engine. I do not agree about the injectors. The truck will wear out before the engine does.

I have a 1996 buick 3.8cylinder (pretty much same engine) my car has 190,000 miles on it and still runs great! but obviously if ou want it to last you need to change the oil and you can't beat the hell out of it (accelerate by getting it to 3500 rpms, etc.) Great engine! i should be able to get 250,000 out of it no problem
