Overview
The Fastrax Racing Pure Silicone Oil 15Wt (FAST60-15) is a professional-grade shock and differential oil specifically engineered for RC car enthusiasts across the UK who demand consistency, precision and performance tuning capability. Whether you're competing at the highest levels or enjoying weekend bashing with your RC car, this 15-weight silicone oil delivers the stable viscosity characteristics needed to dial in your vehicle's suspension and drivetrain perfectly. Developed through rigorous 12-month testing programmes conducted by some of Europe's leading RC racing drivers, this oil has been proven in conditions ranging from the intense heat of Spanish circuits to the challenging wet weather of the UK, ensuring reliable performance no matter where your RC hobby takes you.
This specialist racing oil is part of Fastrax's comprehensive range of suspension fluids designed to give RC car owners unprecedented tuning flexibility. The extensive range of viscosity options available means you can fine-tune your vehicle's handling characteristics for your specific driving style, track conditions and weather. From lightweight oils for responsive steering and quick weight transfer, through to heavy-duty formulations for stability and controlled power delivery, the Fastrax Racing Pure Silicone Oil range lets you extract maximum performance from your RC buggy, truck, or crawler. The innovative easy-pour lid design transforms oil changes from a frustrating, messy chore into a quick, straightforward maintenance task that takes moments to complete.
Racing drivers involved in the development of this oil reported that they had never encountered oils offering such excellent consistency and smooth progression through the entire viscosity range. This level of predictability is crucial when you're competing for championships or simply trying to improve your lap times. The 15Wt weight sits in the lighter-to-medium range, making it ideal for drivers who want responsive handling, improved steering feel and quicker chassis reactions, particularly in conditions where you need agile weight transfer and nimble directional changes.
Key Features
- Professional Racing Grade Formula — This oil has been developed specifically for competitive RC racing rather than casual use, meaning it maintains consistent viscosity across temperature ranges and driving intensities that would cause inferior oils to break down or become unpredictable.
- Pure Silicone Construction — Pure silicone formulation ensures superior thermal stability compared to synthetic blends, which means your shock and differential settings remain consistent even during extended driving sessions or in varying weather conditions across the UK.
- 12-Month Development Programme — Tested extensively by professional European RC drivers in real-world conditions from Spanish heat to British rain, this oil has been refined to deliver consistent performance across all climate conditions and driving scenarios.
- Extensive Range Progression — Part of a comprehensive viscosity range, this 15Wt oil integrates seamlessly with lighter and heavier weight options, allowing drivers to make precise tuning adjustments that directly translate to improved handling and lap time gains.
- Innovative Easy-Pour Lid Design — The specially engineered pouring lid transforms what is typically a frustrating, messy maintenance task into a quick operation taking just moments, keeping your hands clean and reducing oil spillage during changes.
- Superior Consistency — Racing drivers universally praised these oils for offering more consistency and smoother progression through the range than competing products, meaning your tuning adjustments are predictable and effective.
- Shock and Differential Compatibility — Engineered for use in both shock absorbers and differential units, this single oil type simplifies your maintenance routine and ensures optimal performance across your vehicle's suspension and drivetrain systems.
Technical Performance
The Fastrax Racing Pure Silicone Oil 15Wt is specified at 150 centiStokes (cSt), measured according to standard viscosity testing protocols. This 15-weight designation places it in the lighter-to-medium range of the Fastrax racing oil spectrum, making it the ideal choice for drivers seeking responsive handling characteristics and quick chassis reactions. The pure silicone formulation ensures that the oil maintains its viscosity characteristics across the temperature variations you'll encounter in UK weather conditions, from cold winter mornings to hot summer racing events. Unlike cheaper mineral or partially synthetic alternatives, pure silicone oils resist viscosity breakdown under the sustained stresses of competitive RC racing, meaning your tuning settings remain accurate and predictable. The 150 cSt specification has been carefully calibrated to provide the optimal balance between shock responsiveness and controlled damping, allowing you to enjoy both nimble cornering and stable platform when you need it. This weight is particularly effective for smaller-scale RC cars and for drivers who prefer an agile, responsive handling balance that rewards smooth driving technique. The engineering precision that goes into every batch ensures that you receive an oil that matches the exact specifications published by Fastrax, with no variation between bottles that could affect your vehicle's performance consistency.
