Remove the filler cap then pump the vac pump, this draws all the oul up the tube and into thr oil suckered. When it's doing that, remove the oil filter. This should get 99% of the oil out.

    I found if you stick the tube in, it will only suck oil 'locally'
    You’re soon to learn there isn’t a suction oil removal port so people using the dip stick hole is all that’s available. So back to sump plug you are unless you have success getting a tube down the hole into the right place.

    Stahlbus, a small well positioned access on the bash plate and it’s all easy…

    Yeah back to the old fashioned dipstick (some on aulro will be ecstatic about that), but I reckon fitting a suitable rubber bung OVER the dipstick tube should allow enough vacuum sealing to suction out the oil. I've only done 1800km in the new steed, so early days yet....

    A dipstick tube will not go to the bottom of the sump, you won’t be able to successfully drain using the method you propose.

    I assure you it’s quicker and cleaner. No vacuum lines to clear and stash. Just a single drain tube, quick rinse, in the plastic bag and back in its pelican case in the car for next change.

    Sucksess

    Good news
    I did a second intermediate oil and filter change recently at 20000km
    This time using the the suction method down the dipstick tube, I extracted the full 8.8 litres
    Last time using the same method I only extracted less than 6 litres
    Maybe as suggested the tube was curling back up at the bottom earlier

    Our local (now out of business) dealer said they use the extraction method rather than the drain plug method

    I still plan fitting a Stahlbus or Fumoto drain valve with and access hatch in the bashplate, but am I little concerned about warranty issues

    Only warranty issue would be a failure of the valve and loss of oil. Impossible as the Stahlbus has a cap to secondary seal it

    10000km oil service just done the traditional way, bash plate removal and drain via sump plug. I was somewhat surprised to see how black the oil was after "only" 8 months, brought back diesel v6 memories. New genuine filter and just under 9l of castrol edge professional C5 0W20 went in. Still looking into the stahlbus valve modification.
