Like everybody has been saying. Before you loosen the filter, punch a hole at 12 and at 6 in the end of the filter, farthest from the engine. Put the modified oil container under it to catch what drains out. When it's stopped draining then use the sammich bag over the filter when you pull it off. Have the replacement filter gasket oiled and ready to go and you won't have much to clean up. While you are waiting it will give you time to check over the machine.
