Oil change using oil extractor pump

[Ludwig]

Is it possible to change the oil using an oil extractor pump?
That dip-stick tube looks a bit narrow

I want to carry out a quick oil change on our Countryman Cooper petrol.
It will be one year old soon.

I always think youre better off removing the sump plug and doing it the correct way, the hot oil will flush out any bits and debris better that way.
Ive seen garages using them, normally to save time so they dont have to remove undershielding and guards etc, if youre doing it yourself cost in time doesnt matter, does it?

I'm sure you're right.
On the other hand, the inside of an oil filter is when oil has been changed regularly, is surprisingly clean (I'm talking petrol engines here of course!).
You wonder why you bother going to the cost and time of changing the filter.


<Ive seen garages using them, .... >
I don't suppose that would include MINI dealer garages by any chance?

I know garages do use the extraction method.
I don't think they will tell you unless you ask them!

It's not so much the cost in time, but rather it is so easy, clean and quick.
I did it regularly on the last car, Golf GTI.
I kept that for 5 years.
Never used any oil (of significance).
Ran as good as new when I sold it.

Extraction of oil thru fill was initiated in boats for the complication of reaching the sump plug. Some genious decided to sell it to auto mechanics for ease of change and they could make more money by time save. The Coopers oil filters or reached thru the top engine area which makes it tempting to not crawl under car and drain all oil. You leave up to 3/4 liter in crankcase and this is contaminated oil which you mix through out the system. It's fine if you sell car in a few years but for long term ownership ( of which I keep most cars 10-15 years ) I would recommend drain it. In other makes , you have to crawl under to do the filter, might as well drain it and CHECK DRAIN PLUG FOR METAL SHAVINGS!

between my cms all4 and my dad's cms all4, i have done 4 oil changes so far

i do not see the need to use the top extractor, i do not lift the cars or even use a ramp, there is plenty of clearance under the car for the drain pan and access to the drain plug

i warm the engine, pull the drain plug, slightly loosen the oil filter and do something else for 30 or 45 minutes, that way the engine has cooled before i reach in for the filter

i refill the sump with 4 quarts of oil, that puts the level at about 1/2 after running the engine to fill the oil filter, neither car uses any oil betweem changes

Ccoker & bmwr606, many thanks for your advice.
Very useful to me.
I might have a go at crawling under the car.
Sorry for the delay in responding.

if your question was for me, i bought a new 03/2012 build 2012 cms all4, my dad liked it so much that 2 weeks later he bought an 09/2011 build 2012 cms all4 ex dealer demo with 2,500 miles

1st oil/filter change was dad's the day after he bought it
2nd was my car at about 1,800 miles
3rd was on my dad's at 4,500 miles, half way to his first scheduled free change
4th was on mine at 4,500 miles, 1/2 way to first scheduled free change

both of our cars started with the OBC showing 9,000 to first change, dad's came up by time at 1 year and 8,000 miles and mine counted down to zero at 8,000 miles from the initial 9,000

both cars came out of the dealer showing 8,000 miles to the next change on the OBC, according to my dealer, 8,000 is the latest/greatest bmw/mini scheduled interval

and yes, we both have 3 years free service but i will be doing additional changes at 4,000 miles between the dealer free service

edit: i actually bought the extended maintenance with my cms all4 so i have 6 years or 100,000 miles "free" service ... i keep vehicles a long time, my last (i still have it) i bought a 1997 gmc sonoma in 12/1996, it has 288,000 miles now
