Best suction oil pump for oil changes
 

I am about ready to make the change to this type of oil change but before buying a pump, thought I would your opinions on which one to buy.

Last week, a local marine supply house had some in their monthly flyer for $59.95 and it looked OK but not knowing anything about them, decided to wait.

Somewhere on the net a few months ago, I read that some of those pumps do not work well or maybe not all all with hot oil and I prefer to change the oil while it is hot or at least very warm.

Thanks

Can't comment on which one is the best but will mention - make sure it holds at least 8 qts.

Make it easy on yourself. Go back to the marine parts store, spend $125 for an electric suction pump which is a lot faster than the hand pump type. The time you save will be worth it - especially if it is really cold or hot when you're changing the oil. There is nothing wrong with a Topsider - except that it and other hand pumps are slow. I change the oil every 3000 miles, so I want efficiency. Also, After I add the new oil to the engine, I reverse the pump and pump the old oil into the 2 used gal. oil containers which are taken to the recycling center. And, the oil containers hold close to 5 quarts, so if you drain 8.5 or so quarts, you still only have two containers to cart away. Figure it this way: after ten oil changes, charging yourself $12.50 an oil change, the pump is paid for. It sure is cheaper than the dealer! :)

I just lile to plain and simple "see" it empty. In fact, I plan to pull the pan every other oil change to look around, I figure the 30 mins extra is a chance to meditiate.

I suppose I can't blame someone for not wanting to get on the ground to drain it out, but I don't even have to use a floor jack to drain the oil in my 300s. Just a simple turn of the wrench.... Or I seen there is a quick drain which you just unlock the drain and it shoots out your oil, no tools required (not sure if they have it for our MBs, but they are only $20). I just can't see spending $130 to pump it out the dipstick tube, I guess in any case it is better than going to the stealership to have it done.

I just bought a MityVac fluid evac plus from www.thetoolwarehouse.net/shop/MIT-7201.html
for $54 plus shipping. I have only used it once,
but I am quite pleased. I gave it 10 strokes, and
it drained 4 quarts slowly while I removed the
oil filter. After 10 more strokes, it drained the
remaining 4 quarts before I could replace the
filter o ring on my e320. It was money well
spent.

I have no experience with the topsider, etc.

Here you go...
 

I purchased this self-priming electrical pump for oil changes and it's great and only $45. I've used it for 2 oil changes and so far so good.

You just have to attach polyethelene tubing to each end and you're ready. It takes les than 5 minutes, no fatique from pumping, no mas.
