Well I have just finished doing an oil change using the Scavenger System. Boy what a F@#$%^ around but I have done 20 klms and instead of a streaky dark oil on the dip stick the oil is clear.
I am giving the system the thumbs up. Hopfully I will be able to do changes a bit quicker with less mess!
It only took a couple of weeks to ship from USA. Have a look at http://www.rouguechopper.com

I've got a scavenger too.First time I used it the transparent hose came off the oil return line,what a fucking mess it made, but I have to admit it does flush alot off dirty oil out.
