Does anyone on this forum use a fluid extractor for their oil changes? They seem to be pretty popular in some other car communities but I don't read a lot about them here. For a DB9 it seems helpful because it would eliminate the need to get under the car, given how the oil filter is removed from the top, as well.

 

I drain from the multiple drain holes...I use an extractor when I over fill my oil tank!

 

The dipstick tube on the DB9 is pretty thin. I have a Topsider extractor that I use for the Mercedes, but its tube is too thick to fit in the DB9. If you found a tube thin enough you might be able to do it, but it would take forever to get all the oil out.

 

concur, even with the smallest diameter tube that came with mine I couldn't do a complete extraction. It would work to get an oil sample for analysis but that is about it.

 

Oil extraction only pulls the oil from the top and leaves the junk behind in the sump . The idea of changing your oil is to remove the junk . I would never use an oil extractor .

 

I used it for both front and rear.
the rear needs the modifiers. Front does not require them and oil is good for using there.
I don't know if motul is good you will have to search for cross reference tables on that. I know others have used other oils but you'll need to research which. Google and search this forum. I've had zero issues with my fluids.

 

Holy thread from the dead, and with almost no relevance to the original! Well done, sir.

I concur.
It is always best to clean your junk.
You get some best action with clean junk anyway.

 

I was very skeptical on the use of these oil extractors and being in the trade, took the opportunity to test one out on a number of cars.

As long as you have fully warmed the engine oil through (as you should anyway before dropping the oil), the "junk" in the oil should be in suspension in the oil, especially with modern, synthetic lubricants. Anyway, I "vacuumed-out" 5 different cars with the extractor in the dipstick tube and after that, lifted the car and removed the sump bolt. I expected there to be a pint or so of oil remaining but no...........the sump was effectively empty, probably just a couple of egg cup fulls, and that was probably just from components draining in the engine whilst I was lifting it.

It's great to use it with most cars now having those damn undershields with no access hole. I did an Audi recently with 24 undershield fasteners in 4 different tool sizes!!

So now I use the airline operated vacuum extractor wherever I can. I only came across 1 VW engine that would not allow the tube down the dipstick.

 

I also have one of those Oil extractor but I dont use it on cars that I have to lift to remove the oil filter as I am already under the car but I use it on all the cars that I own or use to own with oil filter at the top like my 2021 Audi A4 and my now sold 2017 Jaguar XE.

 

I use an extractor on all my vehicles except for the vantage... while I'm under the car on my Quick Jack I check everything. Besides the filter is under the car

 

only use those top extractors when u over-fill. Our AM's have multiple drain spots, so youd never get all the old oil out from the top...or anything thats resting at the bottom
