Oil Evacuation: Home Brew!
Here's a picture of the oil evacuation device I made. There's no electric motor to wear out (except for my compressor) and nothing to hand pump! It uses a venturi/vacuum device to create the suction. Also, there's no skinny dipstick probe to restrict the flow.
I changed out the oil in my C280 and also in my friend's E420. After the device sucked all it would suck, I pulled the drain plug on the E420 (after removing the oil filter) and still got several ounces of oil out the bottom. I don't know why there was still oil in there and it concerns me. If it's not getting all the oil out it becomes merely a cool toy without any practical value!
