I'm lazy and use a sucker outer, down the dipstick tube.
Do it every 6 months or so, but last time took it to Nationwide for filter and oil, charged extra ?10 to take the undertray off!!!
I know Ritchy will say you leave all the swarf and crud in the bottom of the sump, but its such a bind dropping it out the plug hole. Either goes up your arm or over the drive.
Maybe I could suck it out then undo the plug and wont have the same amount to rush out.
