Just read an article in The Star, highly recommending sucking the oil out through the dipstick tube. The device they used was a "Topsider." Available from Griot's Garage (www.griotsgarage.com) for $40-$65.
I personally am going to buy one, after reading the article.
No more jacking up the car to change the oil!
They make the statement near the end of the article "MB cars have been designed for suction oil removal since 1976."
