Silicone Oil #5000 is a specialized lubricant designed for use in oil gear differentials in R/C models. This high-viscosity oil enhances your model's cornering abilities, which can significantly improve performance during high-speed runs. By experimenting with various viscosities, users can tailor the oil choice to meet specific driving conditions. While high-viscosity oil is recommended for faster, more stable cornering, low-viscosity options may be better suited for slower speeds, allowing for fine-tuning of handling characteristics.
