synthetic oil keak
I changed to Mobil 1 10-30 in my '79 450SL at 70,000 miles. I did notice some good size puddles of oil under the car. When I would check the dipstick it read low, so I would add more oil, up to the full mark on the dipstick. Then more puddles of oil, puddles meaning about 6 or 8 inches in diameter. WRONG. I have now learned that my car likes to have between 7 to 71/2 quarts of oil not 8. It seems to purge out the excess oil. Keeping the oil at this level I have no leaks with synthetic.
