Not a fan of these suction pipes down the dipstick hole myself but I know lots of garages do use them now.

To be honest I am ignorant of whether they are as effective as a traditional drain or not but, as I take care of my car, I need to know if the fact that he has used one on my oil change is likely to result in it not being as effective as a traditional oil drain.
There seems to be evidence to suggest that any oil left after using the suction method is completely insignificant. If that is the case then I'd be tempted to invest in one myself as it will save me significant cost and allow me to change my oil myself more frequently.
Does anyone else have a view or experience of using one?
I guess the experiment is to use one THEN remove the sump plug and see how much remains. I am just not sure how much 'old' oil is enough to render 'new' oil contaminated.
Thanks again.
