Always put 3.7L when oil filter is changed and 3.2 - 3.3 litres when oil filter is not changed. Don't over fill. It effects fuel economy and damages seals of engine.
Guard filters are crap as compared to oem ones. Oem filter ensures the cleaning of oil and filters dust particles better than guard and leppon ones. Better stick to oem and change after 10,000km.
