Can Motorcycle Shock Absorbers Be Filled with Engine Oil?

[LeGarrett]

Motorcycle front shock absorbers should not be filled with ordinary engine oil, as their properties and viscosity are different, and using them in shock absorbers will not achieve good damping performance. Suspension System: In the suspension system, elastic components generate vibrations when impacted. To improve ride comfort, shock absorbers are installed in parallel with the elastic components in the suspension to dampen vibrations. Shock Absorber Working Principle: Most shock absorbers used in automotive suspension systems are hydraulic shock absorbers. Their working principle is that when relative motion occurs between the frame (or body) and the axle due to vibrations, the piston inside the shock absorber moves up and down, causing the oil in the shock absorber chamber to repeatedly flow from one chamber to another through different orifices. At this time, the friction between the orifice walls and the oil, as well as the internal friction between oil molecules, creates a damping force that converts the vehicle's vibration energy into heat energy of the oil, which is then absorbed by the shock absorber and dissipated into the atmosphere.
