|  Shock Fluid 
			
			Motorcycle shock oil is avaiable in 1 litre bottles it can be fully synthetic with very good water rejection properties. Oil is available from 5 wieght to 30 wieght you can therefore choose the amount of damping you need.

|  Engine oil 
			
			The Australian Army driver's handbook for Ford CMP's recommends using SAE 50 engine oil for the shock absorbers "For Temperate climates". As Engine oil is also available in a range of viscosities, you could tailor your damping rate, too.
