Arrowmax am-210033 RC Silicone Diff Oil 59ml 300000cst  [am-210033]

RC diff silicone oil — 300000cst

Arrowmax am-210033 is a 59ml bottle of silicone differential oil specified at 300000cst for use in hobby RC differential units. It is presented purely as an RC-scale tuning accessory and does not imply suitability for any full-size vehicle application.

The oil’s main function is to change internal diff damping. At higher viscosity settings, internal resistance between gear teeth or ball mechanisms increases, giving a firmer differential feel and altering cornering and traction behavior on a variety of surfaces. Lower viscosity allows freer differential action.

Service is commonly performed by draining the existing fluid, cleaning internal parts, and refilling to the differential manufacturer’s specified level and procedure. Because differentials vary by design, always follow the instructions provided with your chassis or diff kit.

When experimenting with viscosities, make small incremental changes and test in consistent conditions to evaluate handling effects. Keep notes on each setup iteration. After use, keep the cap tight and store the bottle upright to avoid contamination and evaporation.
