Hi,

I happen to use a Stearns electric oil change pump. It was about $35 and runs off the battery.

I get the vast majority out of the engine, and the ease of doing it makes that job fly by -- about 20 minutes.

I look at the underside of the car as well.

There is another thread about this topic and is on a 126. Owner did both types of draining procedures -- pulled plug and suction. Suction got more oil out by a number of ounces. He has photos of the results.

Either way, change it hot and often and you'll be fine. A few extra ounces will certainly not hurt your new oil. Even if you let all the oil drain overnight, there is still more than you think up in the motor.

Regards,
