Oil & Oil Filter change.

[bozboz]

I use an old wood chisel, though a sharpened screwdriver would work just as well.
Rather than punching it through the filter place it at the rim of the filter and tap it gently with a hammer a few times in the unscrewing direction.

Second that if you dont have a rubber grip/filter wrench. If you whack the screwdriver thru you end getting oil everywhere! Dont forget to go for a ride before draining your oil gto help it flow easier (but watch your fingers on the hot engine/exhaust).
