using an oil extractor pump for oil changes

[pattox]

I was wondering if anyone with an Aurion has used one of these sump oil extractor pumps (Pela, Mightyvac etc) as an alternative to the normal drain plug method and if so, how well do they work?

I understand that these pumps work well with some cars, and not at all with others but I haven't read any user reports involving the 6 cylinder engines in the Aurion/Lexus and Kluger.

Why not just drain the oil via drain plug? It would be more thorough and you dont need to raise up the car at all. I dont see any good reason to use this method but there is a good reason not to. If you leave the drain plug off and let it drain for a few hours you will remove a far larger amount of the crap that collects on the bottom of the pan. Mine is still dripping slowly after an hour. That is also a reason why dealerships and shops dont do such a good job, they are quick and don't let the oil drain out for a long time
