Have just bought a 2004 Copen and first thing, change the oil and filter. The previous owner had receipts for regular service including oil change but the oil was like treacle and I suspect neither oil nor filet have been changed for some time. I purchased the listed oil and filter. Reviewed the previous information on changing the oil filter through the engine mount. Bought 2 different types of filter removers from large auto parts outlets, couldn't use them, so finally went to a small auto parts outlet and got the right service. I ended up with the correct filter remover (RYCO RST202, 68mm, 14 flutes) and removed the old filter. Tried to fit the listed filter (RYCO Z443) and it would not fit through the engine mount. My small auto parts outlet then sourced the right filter (Also made by RYCO apparently) Its a WESFIL filter WC083 and was half the price of the previously purchased, incorrect filter. See attachment.
