Hi guys, Checked valve clearance yesterday (SvRS indicated '9' and I follow this to the letter, no more, no less maintenance). Car has used from the beginning onwards always and with no exception at all Honda original 0W20 oil (100.000 km/62.500 miles). I want to share this with you because there are still people 'out there' who doubt on using 0W20 oil: - absolutely no sign of any contamination around the valve train (black sludge or any other form of contamination) or in the inside of the valve cover. All looks shiny new. - all 16 valves still had the perfect factory clearance !! Not even one needed any adjustment. I have known other days when driving French cars. - every single part had a perfect film of oil on it (when feeling on the lobes especially this is very important). I love this oil in combination with such a quality engine! Usage of the engine: At the moment of taking pictures (100k km) the oil was in it 10.000 km. Engine has had it hours of traffic jam driving, but majority is highway miles. Most of the time in low revs, but sees almost every time I drive her approx. 5k RPM.
