Oil Changer Pumps

I have been looking into purchasing one of those pumps that empty the oil from the engine for those engines in hard to reach areas. Has anyone had experience with the units that drain the oil by putting the tube into the dipstick hole or the oil fill hole? I like the idea but I''m wondering if the tube would get all the oil, even from the bottom of the crankcase. Don''t want to leave any oil at the bottom and overfill. Thanks!

I use a Big Boy Topsider and I''ve found it to be quite effective. The most important thing is that you run up the engine to operating temperature to get any particles up in the oil before you start to pump the oil out. Any pump will leave a little oil residue, but not enough to worry about. Feedback I''ve received from other people is that the inexpensive electric pumps (drill attachment for example) aren''t worth the money. Jabsco makes a good electric oil remover pump and it sells for about $130 as I recall.

I use a rotary pump that can be drill powered or hand powered with a vice-grip. If I serviced marine engines for a living - I''d opt for a better method, but for the 3 to 4 quarts in the cankcase that I drain twice a year - the $20 pump is good enough.

I have one of these units also. You do need to ensure the dipstick leads to the bottom of the oil pan to get all the oil.

The easiest way to confirm this is to pump out the oil, and see how much has been pumped in to the unit. Mine has markers for each quart.

Works great for my Atomic 4 engine.
