My '81 300SD is giving very poor mileage, latest filling showed about 19 mpg. A recent long trip produced only 24 mpg. Also, on cold starting and heavy acceleration, the car lays down a smokescreen that would be the envy of a World War I destroyer. Car was recently serviced -- valves adjusted, filters changed, etc. Runs very well with excellent acceleration. Has been starting in the coldest weather with no trouble. But it should not be smoking like that nor should it deliver such poor mileage. Any thoughts?
