| Team Losi Racing Silicone Shock Oil 40WT | Balanced damping for all-around performance |
| 2 Bottles Racing Silicone Shock Oil 50WT | Cost-effective bulk option; consistent 50WT |
| Team Losi Racing Silicone Shock Oil 30WT | Lower damping; responsive steering |
Liberty Oil 1oz Synthetic Lubricant for RC Cars
Includes a 1 oz bottle of 100% synthetic lubricant, designed for RC hobby use. Best for hobbyists who want a simple, single-source lubricant that works across small drivetrain components. The product comes with a 1.5 inch, 18 gauge stainless steel pharmaceutical-grade applicator for precise application.
Best for: Beginners or casual RC enthusiasts who need an easy-to-use lubricant with a trusty applicator. Caution: It’s a general-purpose oil; for specialized shock damping, consider viscosity-specific oils below.
Team Losi Racing Silicone Shock Oil 50WT 710CST
Designed as a 50WT shock oil, this option is aimed at better damping on rough or uneven surfaces. Fits standard electric car and truck setups. The product origin is the United States, with packaging dimensions listed for typical RC builds.
Best for: Runners seeking firmer damping to handle bumpy tracks. Better for: taller suspension travel or heavy-duty rigs. Caution: Availability of matching viscosity options may be limited in some carts.
Team Losi Racing Silicone Shock Oil 40WT 516CST
This 40WT oil provides a balanced damping profile suitable for general racing conditions. It’s listed as a United States origin product with standard packaging dimensions for RC shock oil applications.
Best for: Versatile racing setups that require smooth, predictable damping. Choose this if you want a middle-ground viscosity. Caution: May not provide enough damping for very rough tracks without adjusting spring rates.
2 Bottles Racing Silicone Shock Oil 50WT
A bulk option featuring 50WT shock oil for RC cars and all vehicle types. The two-bottle setup is cost-efficient for hobbyists who run multiple cars or want backup stock of the same viscosity.
Best for: Budget-conscious builders or teams needing consistent viscosity across vehicles. Limitation: The listing emphasizes 50WT; if your setup requires a different viscosity, you’ll need alternate products.
Team Losi Racing Silicone Shock Oil 30WT 338CST
This 30WT oil offers lighter damping, improving steering responsiveness on smoother tracks or tight courses. Packaging dimensions indicate a compact product suitable for smaller RC models or lighter setups.
Best for: Drivers who want quicker chassis response and lighter damping. Avoid this if you race on rough surfaces that demand higher damping to prevent bottoming out.
Buying Guide: How To Choose RC Silicone Oil
Viscosity matters. Higher numbers (like 50WT) provide stiffer damping, while lower numbers (like 30WT) yield lighter damping and quicker response. Match viscosity to track conditions and vehicle weight.
Application context. Some oils are designed as general lubricants, while others are specialized for shocks. Use the latter for damping control and predictable handling.
Quantities and cost. Bulk options save money when you own multiple vehicles, but ensure the oil’s viscosity matches your needs for each car.
Origin and compatibility. Consider products with clear origin information for consistent manufacturing standards. Ensure the oil is compatible with your RC shocks and springs.
Frequently Asked Questions
- What does WT mean in RC oil? The viscosity rating (WT) indicates how thick the oil is; higher WT means thicker oil and stiffer damping.
- Can I mix different viscosity oils on the same RC car? It’s best to avoid mixing viscosities on the same shock; choose a consistent viscosity per shock or per axle.
- Is silicone oil better than mineral oil for RC shocks? Silicone oils are common for RC shocks due to stability and temperature performance; mineral oils are less common for high-end shocks.
- How do I know which viscosity I need? Start with the track conditions and vehicle weight; adjust gradually by testing damping feel and bottoming behavior.
- How should I apply silicone oil to shocks? Use a precise applicator to prevent overfilling, and follow the shock design guidelines for oil volume.
- Are there safety considerations? Use in a well-ventilated area and avoid skin contact; wash hands after handling.
