What’s the viscosity of 2 stroke TCW-3?

[Elkins45]

Just curious: if TCW-3 two stroke oil was rated like four stroke engine oil what rating would it have? I know before the development of dedicated two cycle oils the outboard makers just mixed straight 30 weight, so my guess would be that it’s somewhere around there, but that’s just a guess.

Since the viscosity at 100C can range from 6.4 cSt to 14.5 cSt the SAE Grade would range between between a 20 Grade to a 40 Grade.

Thank you.

Mystic TCW-3 is 6 cSt at 100 C.
