Anyone using Griot's vacuum extractor to extract the engine oil via the dipstick tube on the X100?

Any *experience-based* comments on how well that extractor functions? Two different diameter extraction tubes are provided - which one works best?
I am not too concerned that all the old oil is extracted via this path since I will be finishing up draining the remnant via the usual sump drain.
Just trying to forego that initial oil gusher out the sump drain.

 

The thru the dipstick extractors are inefficient in getting out the bottom layer of filth that resides in the recesses of the lower crankcase and oil pan. The growing use of them does not mitigate this fact.

i use the lever operated system made by Fumoto. There are several models that fit our oil pan plug threads.


it’s fool proof, and you can attach a drain hose to it with the other end in your receptacle pan. No need to spill a drop of oil. It’s impossible for the valve to open by accident and they have a clip that prevents the valve from opening if the safety spring fails.

I attach a 3/8” or 1/2” ID clear hose to the permanently attached Fumoto valve and stick the other end into my used oil holder. One turn of the valve and I walk away for 5-10 minutes or so. Turn the valve off and I’m done until the next time.

Amazon sells the Fumoto valves. I’ve had mine for 5 or 6 years. Since my car is a daily driver, that works out to 15-20 oil changes.

i learned about them in this forum, IIRC.

i use a short nipple version, but this photo is representative of the valve:

I already have the Fumoto valve (as illustrated above) installed on my XKR. I am aware of the sludge-left-behind issue for extractors. I was just trying to solicit anyone's actual experience using the Griot's vacuum extractor.

 

the Griot extractor you referenced is just a re-badging of the Mity-vac product (which I own). I use it for the rear end fluid changing, where there is not a drain plug in our cars . I’ve also used it when I’ve added a bit too much oil to the transmission . I would not recommend using it for engine oil changes, or in lieu of completely draining the transmission with the drain plug, for the aforementioned reasons.


if you have the Fumoto valve already how can you have the need to “…Just trying to forego that initial oil gusher out the sump drain….”

With a hose attached to the Fumoto valve and the other end in your drain pan, where is issue with oil streaming out into your drain pan. Not a drop of oil gets on you or is spilled elsewhere.

just trying to understand what you are trying to achieve.

i use this type of drain pan:



I put the hose into the center (with the plug removed) and just replace the plug when done. It remains sealed up until taken in to the oil recycling facility.

@zray. Apologies for being so confusing. Just fishing for input. My XKR arrived already fitted with the Fumoto valve. I have a never-used vacuum extractor sitting in the closet. Getting ready to do my first XKR oil change, thus the query. Now see that the topic has been covered in other forum threads. Thanks for the helpful reply.

 

To wrap it up, Besides my feelings that the vacuum extractors leave some unwanted residue behind, one of the reasons I don’t like using it routinely for engine oil or ATF removal is the need to clean out the extractor’s tank throughly with soap and water after pouring out the used oil.

if one does not clean the tank and all the seals religiously, the seals will swell and degrade, making the unit useless after just a couple of uses.

the instructions that came with mine say to “clean after using”. But they don’t explain the consequences if you don’t do a damn good job of it.

I have used them for many years in marine applications. That is the only place they should be used as there is no alternative. Pull the drain plug and do it right.
