I just bought a 1980 300d. The engine runs well & starts right up with frost on the car, temp. in low 30's(starts on the first crank). The car blows very little smoke and no blue smoke can be seen coming from the exhaust when driven.I had my brother drive it so i could check for smoke. Heres the problem its using close to a qt. of oil in 150 miles! Please help ! God Bless Matt (SD,CA)
