11 years old but some interesting test results on various oils used in v twins, carried out by Amsoil so maybe biased.


I use Amsoil V twin 2/50 oil, unless your engine has shown significant wear which I don't think any of us will say then any of these oils will work well, especially as we change the oil regularly.
