G'day all,
It's funny how nobody knows what Victa 25cc oil is.
Actually, we now do - Alan has made a welcome contribution to the ODK knowledge base, via one of his pics.
Many thanks for that, Alan.
As mentioned in one of my earlier posts in this thread, the viscosity is SAE 10 grade. And this is easy to get from motorcycle shops, as 'SAE 10W Fork Oil'; it's usually in 500mL bottles, too, which is handy.
The warning I give about avoiding 'EP' rated oils, is because most EP additives are of sulphur based chemistry, and these will chemically attack 'yellow metal' [i.e. the brasses and bronzes] components, such as bushings and worm gear wheels. And there do exist Fork Oils which claim to be of 'EP' rating.
