Is that castor 927 synthetic? , this 3w is fully synthetic and my lhs says that's why it is run at 50:1.
Being in Australia and probably one of the first ones to own an octane in my state there is no support for it here at all.
has anyone tried or uses this oil , I have some for my my savage octane that my lhs recommended my only concern is that the 3w oil states a 50:1 but my manual most other sources say 25:1
