Oil extractor

[jerem0621]

I'm considering buying a vacuum oil extractor for my oil changes. Does anyone have any experience with these devices? Pros, cons?

Thanks,

Jeremiah

Yessir! I have those on all my vehicles except my motorcycles. Sure makes changing the oil a snap, and also collecting samples for Blackstone Labs.

Fumoto valve. Yes, I had one on my Duramax. If you get the 'nipple' version, just attach a clear tube routed into a drain pan, turn the valve, and go relax somewhere for a while. Makes life easy when you need to drain 10-15 qts. Gets rid of that big initial splash. NO mess at all. I used to slide a plastic zip tie onto the valve so the arm could not accidently move to the 'drain' position.

But like some else said, I always have a bigger mess changing the filter.

I use one on my 3.0 MB diesel and it works very good. The jeep as too much******to remove I order to get at the plug plus the oil filter is top mounted. It removes 100% of the oil. I have the Mytivac but it doesn't work on my 6.2 GM v8 in my Denali. I put the drain valves on my Yukon and Cummins.
The MB dealers suck out most of their cars through the dip stick.

Yeah, when the oil filter is accessible from under the hood it sure is nice! My son's Saturn is like that.

Well on my Cummins I change the filter from under the hood, much easier.

It takes long enough to drain out the 3/4" hole in the pan, can imagine how long it would take to pump out 3 gallons!

Used one on a Mercedes convertible my wife had and it was kind of a PITA. Took FOR EVER to get the oil out.... and yes it was warmed up. There only so much fluid that can move through something the diameter of a cocktail straw.

I'd never do it again if I had access to the drain plug.

I use this Liqui-Vac on all my small engines, snowblower, power washer, etc, where the drain plug is not very accessible. Not sure I would use it on a vehicle, as was noted, you need to get under there and change the filter anyway.

This is much better and just as clean.

If that in deed is the case, it is designed to have the oil removed that way.

Exactly works quite well.

Boat engines are plumbed and designed to have the oil removed by some kind of pump or extractor. The dip stick is mounted to the oil pan at the drain location with a Banjo bolt. This enables the removal of anything that settles to the bottom of the pan. In a car or truck, the dipstick tube does not go to the bottom of the pan, and most are attached going through the block, several inches above the bottom of the pan. By using the extractor method in a car or truck, you will not be able to remove all the oil or any debris that has settled to the bottom.

I used one for decades on my boats ,like previously stated oil must be hot because the hose is tiny.
Would never seriously consider using one if a drain plug was excessable
