A couple of questions:
1. How many miles should a 1995 300e diesel non turbo motor run before
major overhaul. I know that scheduled maintenance has a lot to do with
it and also how and where it has been driven. I have one that had 180k
when I purchased it and have driven it for about 18k. It doesn't smoke
but will use 1-2 quarts oil between changes (every 3000 miles). Some
oil leaks somewhere out from the bottom front of the engine but not
that much.
2. I notice that at 3000 rpm I am only going 67 mph. Is this normal or do I
have transmission problems. The car is slow in town and takes awhile
to get up to crusing speed. I take it that a diesel with only 135 hp is
this way. I gets great fuel mileage so I don't think the transmission is
messed up but I don't know. Another thing is the noise inside the
car.
Thanks L L L

In those 15 years what kind of oil was used and how often were the oil and filter changed ?
Was it ever overheated ?
These are generic questions which apply to all cars.. but the oil question is more important for diesels.....

In answer to your question????????

If maintained well, it will go 500,000 miles and still run like a swiss watch.

the n/a 3 litre straight six was 115 bhp

2900/3000 rpm @ 70 mph is about right for a 4 speed auto with standard tyres etc.

2500/2600 is maximum economy.
