172 Cup
Wanting to change the oil and filter on my 172. I've had a look and seen that I need 5.1 litres of oil. Do I really need the 0.1 litre of oil as everywhere I look sells in 5 or 1 litre bottles. Also is there any type of oil filter I need I had a look on here http://www.opieoils.co.uk/oil_filters/ and seen several.
