Couple of thoughts, Ken.

If the oil is too hot, and depending on what the tubing of your pump is 
made from, the tubing can melt (and solidify) in your dipstick tube. 
Most people will bring the engine up to operating temp, shut off and 
let sit for 20 mins before pumping.

The dipstick tube goes down to within a mm or two of the lowest point 
in the oil pan (see attached). If you fit your pump with a larger hose, 
so that the hose fits relatively snugly in the top inch or two of the 
dipstick tube, you will be able to empty the engine in two minutes. The 
hose does not need to go to the bottom, if it seals up in the top of 
the dipstick tube. The tube becomes the sucking device. Two minutes. 
Really, it will work this quickly. And you shouldn't need to elevate 
the rear of the car.

Once you get this stuff sorted out, changing the oil filter will take 
more time than anything else.

Regards,
Steve
