Not sure on the SCV6 but the SD/TD(guessing the same) V6 there is a pipe on the front drivers 'corner' of the engine. Use an oil transfer pump- 12v clips to go on car battery. I bough this one:
DC 12V 100W Car Engine Oil Transfer Extractor Pump Fluid Diesel Electric Siphon | Crazy Sales
there are cheaper options, but I liked the look of the steel pump casing.
The larger supplied tube is the perfect size to go over the engines extractor tube. You just put one tube over the extractor pipe, the other in the receiving container, clip on the battery leads and turn on. Bobs your uncle.... Without my rookie mistake (there was oil everywhere- over me, the car and carport floor....) I reckon you could do the whole job including filter in 15-20 mins.
