The viscosity of many commercial fork oils are listed here

Check the value at 40C in cSt (first column), the usual factory fill "10W" oils used by many Jap bikes will be around 35cSt (Showa SS-8 etc), which is where the Silkolene Pro RSF 7.5W sits (now called "Maintain RSF").
The other significant property is the reported viscosity index (VI, third column) which indicates how much the viscosity changes with temperature, bigger numbers are better. Many oils are in the 150 range, RSF is typically around 300.
