I,ve used a manual oil extraction pump on my C350 cdi the last 2 oil changes. I dont think I have managed to get all the old oil out but it is so much easier, no laying under the car to remove the under panel and sump plug. I,ve done less than 3000 miles between oil changes and have changed the filter both times. I think I could be leaving a litre of oil I can,t extract in it. I like to think of it as being an oil refresh. Any thoughts? Steve.
