TCW3 is the current spec for a two stroke outboard engine oil. TC = two cycle W= water cooled. 3 is the current spec, the previous one was 2.


Would not hurt to run 40:1 but not necessary

50:1 is near enough 1 pint in 6 gallons

20ml per litre if you are where litres are used. (The rest of the world outside the USA)
