Motorcycle fork oils will give a choice of viscosity
I once found charts of testing of motorcycle fork oils, in the viscosity range automatic transmission fluid worked as well as the best, there also was tested tractor multi viscosity hydraulic oil, ---good antifoam, costs less ,as good as best fork oils

My shocks fit tight, originally I filled with jack oil, but have been topping off with ATF because it was in the oil can, been squirting the springs too, had to tighten up the shocks up when the oil soaked into the springs
