Apparently this shock fluid is rebadged "Maxima Racing Shock Fluid - Light". If that's the case then it's a petroleum based oil with 13.9CStr @ 40 deg C and 5.2CStr @ 100 deg C. If you can't get this oil, or the Maxima Light, then Silkolene PRO RSF 2.5WT is a good alternative. It has similar damping figures 13.8CStr @ 40 deg C and a slightly more consistent 5.8CStr @ 100 deg C when heated up. In any event, the price of the genuine oil is not over-the-top at about $20 for a pint.
