My 83 380 SEL is burning oil like crazy and I have to add once every two weeks about a 2 litres. The catylic converter already got clogged from the soot and had to be removed. I only see black smoke out of the exhaust if you floor it but overall the car is running great, it has full power and idles properly but is starting to burn more and more oil.
The car has 250 000 miles but thats not much for a benz that is maintained properly. My mechanic said its normal for benz but at this rate I dont think so. What should I do?
