Differential silicone oil is a decisive factor for the handling and traction of your 1:10 RC car. Depending on the viscosity selected, it influences how much your vehicle turns into corners, how it accelerates and how the power is distributed to the front and rear axles. Soft oil provides more traction in tight bends, thick oil for more directness and stability at high speed. Available in finely graduated viscosities - perfect for precise set-up to suit the track, surface and driving style.
