Dave, I have the larger sized manual/pnuematic extractor from Princess Auto. I used it for changing the oil in the XF without issue. I connect it to my compressor. It was fairly slow (10+ minutes but let me enjoy my coffee while I watched it flow through the tube into the collector. It was really easy and got out almost every drop. Just make sure you release the filter before you start in order to maximize the drainage. I paid about $80 for it. I won't use it again until December.

You are welcome to borrow it if you like. Save the money for something else.

Also, on the matter of the old gas. Canadian Tire has a program for taking back used motor oil and they also take old gas if you put it into something appropriate. At least the service centre at Sheppard and Leslie has taken mine with a nod and a smile. Good old CTC!
