I've been siphoning oil for years on our cars. metal shavings? none. We send our oil out to Blackstone for analysis and all #'s are good.

We've drained the oil normally and compared pickup and it's the same within a very, very small amount. This is great on BMW's where the filters are on top so you don't have to get under the car anyways.

But, for a mustang, with the filter down below, you have to get under there anyways so you aren't saving that much time to siphon.

I used to have a POS thing I bought to change the oil that way on my boat, but it sucked and never got the oil TOTALLY out of the pan. Best bet is to just get under there and play it safe that you go it all out of their and dont over fill cause some of the old oil was still left.

My mom's ML350 (Benz) can ONLY be changed this way without seriously dismantling portions of the undercarriage. And this is not like just a simple cover or something. It just isn't designed to be done from underneath. Rubs me the wrong way mentally, but you get used to it. We just bought a thing that looks like a tank sprayer for weeds in the yard but works in reverse. In ohter words, when you pump the handle it builds suction instead of pressurizing the tank. Has come inhandy for things like tranny fluid too :-)

Got a link? My mom's Kia SUV has a replaceable filter element up top and I would love to be able to change her oil without having to remove the undercarriage shroud from underneath. The one I listed above is fine, but I like the idea of something that doesn't run off the battery.

Thanks,

It should.

You know that once the tube starts sucking air that you've stopped sucking oil. You don't know how much oil is left in the sump because you don't know how far off the bottom of the pan that the top of the tube's opening is/was.


OP - I wouldn't worry if the oil level is only a little bit above. About how much, in fraction of an inch, on the stick?

I didn't measure the overage--maybe 1/4" or so. I thought it would just be a case of putting the tubing down the dipstick tube, squeezing the bulb a few times, and that's it. Not the case!

I wouldn't worry about it. You'd have to overfill it WAY more than that to have it make a difference IMO...

BigDinTexas:
I believe the exact model we use is the MV7400 Fluid Evacuator. Here is their website:

CincyGT, do you use this with synthetics? Reading the reviews on Amazon, it appears the majority of complaints are a result of people using this with synthetics.

Thanks for the info.

Yes. We run ONLY Mobil 1 Fully-Synthetic oils in our cars. Never had a problem...
