Nice! Very good. Can do it every 5,000 km, and then change oil completely at 25,000 km, using a good synthetic oil.
I do 10,000 km per month so every penny that I save on maintenance adds up to a lot.
edit: after 20 minutes of pumping, the oil that is going out is identical to the oil going in. Looks like I hit the point of diminishing returns.
