Oil Extractor Pump Recommendations

Chris,
I have the Mityvac 07400 which is now model MV7400. It comes with all the different size hoses. I only had a problem with it once when the vacuum check valve at the bottom of the hand pump pugged up with sludge. I called Mityvac to find out if they had been having problems with the check and they told me to drain the reservoir after each use. I had left it sit partially full so the sludge settled to the bottom.

Mityvac

62wood let me borrow his Topsider Oil Extractor when I changed the tranny fluid last season. It worked well, I didn't like that I couldn't tell how much was extracted though. I can see how the Mityvac would be better in that regard.

We've got the MV7400 and I'm very happy with it. Works fast and is easy to handle, no spills. Fits in confined places. Found it on sale at West Marine for $50.

+1...been using it for a couple of years and gets the job done.

I have the topside, only extractor I have every used. Worked fine the one time I changed my Trans Fluid.

Guess I should've ponied up the extra $20 for the Mityvac but when you are bleeding money during your first year of boat ownership you gotta save some dollars somewhere.

Chris,
Have you decided and purchased yet?

If your new boat still has the oil pan drain hose it is best to connect to that. It won't siphon,maybe it will if it's lower than the engine but I change them all from inside the boat

Gary, I like this idea. Does the pump come with adapters to fit the oil drain hose? The boat does have a hose, there's just no hull plug within 6' of it.

Once I get it to temp and begin to extract, are you pumping the entire time or does the siphon/vacuum eventually kick in and it sucks itself out? With regards to lowering the suction hose into the dipstick tube, do you simply push it in until it stops an then pull back every so slightly or what? Also, does there need to be a seal around the suction hose and the dipstick tube? I'd think not, but just checking since my previous results were not good. Are you guys able to pull out 4-5 quarts with these pumps?

Getting the fluid warm for better flow is critical. Second, you need to select the proper tube diameter. Some tubes don't fit properly and won't reach down far enough into the fluid reservoir and then only extract part of the fluid. Allow proper venting so that the vacuum isn't fighting against another vacuum.   When doing PCM transmissions, some connect a small flexible piece of copper tubing so that the tube/hose gets all the way down into the fluid reservoir. Just don't let the copper tubing fall off inside the tranny! I have had to push and twist the plastic tubing to get it to go all the way down sometimes. Also, I make sure that the end is not cut at 90 degrees, so that there is not a vacuum block between the hose end and the bottom of the pan. I cut the ends on a 30 to 45 degree angle.

Yes, I can pull out 95% of the fluid in most cases.

Keep in mind that some high end cars (Mercedes/BMW) recommend fluid extraction as the preferred method vs. drain pan and pulling a plug.

Thanks guys. All good comments
