How Much Oil Do You Put in RC Car Shocks?

RC cars are an exciting and fun way to spend time and enjoy the thrill of racing. Many RC car enthusiasts, however, may not be aware of how important it is to maintain their vehicles properly.

One of the most important things to keep in mind when maintaining an RC car is the oil that is used in the shocks. Without the proper amount of oil, your RC car will not perform as well as it should.

Oil is essential for proper shock performance on an RC car and helps keep it running smoothly. Without oil, friction can build up inside the shock which can lead to damage and even complete failure.

It’s also important to make sure that you are using the correct viscosity of oil for your specific model. Different models require different viscosities of oil, so be sure to check with your manufacturer or a local hobby shop for the right type.

In general, most RC cars require between 10-20 weight shock oil. This oil should be poured into each shock until it reaches approximately two-thirds full. If you overfill them with too much oil they will be too stiff and won’t absorb bumps as easily, whereas if you underfill them they won’t provide enough dampening force and can cause instability at higher speeds.


Knowing how much oil to put in your RC car’s shocks is essential for proper performance and safety. Most models require between 10-20 weight shock oil until it reaches two-thirds full in each shock. Be sure to double check with your manufacturer or a local hobby shop for the correct viscosity recommended for your specific model.
