Technical Performance

The Team Associated Silicone Diff Fluid AS5466 has been engineered to meet the precise specifications required by Team Associated RC vehicle owners and competition racers throughout the UK and worldwide. At 12,500 cSt, this fluid occupies the medium-to-higher end of the viscosity spectrum, providing meaningful resistance to differential action without creating excessive lock-up that might compromise traction or increase tyre wear on certain track surfaces. The silicone-based chemistry ensures that the fluid maintains its viscosity characteristics across the typical temperature range experienced during RC racing — from cool morning practice sessions through to hot afternoon competition runs. This thermal stability is particularly important because differential performance is directly influenced by fluid viscosity; as temperatures rise, less viscous fluids become thinner and provide less lock-up, whilst silicone formulations resist this change more effectively than traditional mineral oils. The 12,500 cSt grade represents a popular choice for many RC drivers seeking enhanced traction control and cornering stability, though some drivers may prefer lighter 5,000 cSt fluids for free-spinning differentials or heavier 50,000 cSt fluids for maximum lock-up. The fluid is supplied in a convenient bottle format suitable for differential service and maintenance on all RC vehicle types, from 1/10 scale on-road racing cars and 1/10 off-road RC buggies through to larger scale vehicles. Proper differential maintenance using quality fluids like this Team Associated product is fundamental to maintaining consistent handling throughout a racing season and ensuring your RC vehicle performs at its best every time you take it to the track.

Frequently Asked Questions

• What is differential fluid and why do I need it for my RC car? — Differential fluid lubricates and controls the operation of your RC vehicle's gear differential, which allows the inner and outer wheels to rotate at different speeds during cornering. The viscosity (thickness) of the fluid directly controls how much the differential 'locks up' during turns; thicker fluids provide more lock-up and traction control, whilst thinner fluids allow more free-spinning. By changing the viscosity grade, you can fine-tune your vehicle's cornering behaviour and traction characteristics to suit different track conditions and your driving style.
• What does 12,500 cSt mean and is this viscosity right for my setup? — cSt stands for centistokes, which is the measurement of fluid viscosity or thickness. 12,500 cSt is a medium-to-high viscosity grade that provides substantial differential lock-up and traction control. Whether this is the right choice for your vehicle depends on your specific model, the track surface you're racing on, and your preferred handling characteristics. Always consult your vehicle's manufacturer manual for recommended differential fluid viscosity grades, as different models may call for different specifications.
• Why should I choose a silicone-based differential fluid instead of mineral oil? — Silicone differential fluids offer superior thermal stability compared to mineral oils, meaning they maintain more consistent viscosity across a wider temperature range. This is particularly valuable in the UK where ambient temperatures can vary significantly between seasons. With silicone fluid, your differential will behave more predictably whether you're racing in winter or summer, allowing you to make more reliable and repeatable setup changes.
• Is the Team Associated Silicone Diff Fluid AS5466 compatible with my RC vehicle? — This genuine Team Associated fluid is designed for all Team Associated RC vehicles that specify silicone differential oils. However, before using any differential fluid, always consult your specific vehicle's instruction manual to confirm the recommended viscosity grade. Many other RC manufacturers' vehicles are also compatible with Team Associated differential fluids provided they are specified as silicone-based oils.
• How often should I change my differential fluid? — Differential fluid should be inspected and potentially changed regularly, especially if you race frequently or in particularly dusty or wet conditions. As part of routine maintenance, many RC racers change their differential fluid several times per season. Dirty or contaminated fluid should be replaced immediately. Always refer to your vehicle's maintenance guide for specific recommendations.
• Can I mix different viscosity grades of differential fluid? — It is not recommended to mix different viscosity grades, as this will result in unpredictable handling characteristics and make it difficult to assess how setup changes affect your vehicle's performance. Always drain your differential completely and refill with your desired viscosity grade when making changes.
• What is the difference between 12,500 cSt and other available viscosity grades? — Team Associated and other manufacturers offer differential fluids in multiple viscosity grades. Lower viscosity fluids like 5,000 cSt provide minimal lock-up and a more free-spinning differential, suitable for drivers seeking ultimate traction. Higher viscosity fluids like 50,000 cSt provide maximum lock-up for maximum cornering control. The 12,500 cSt grade sits in the middle, offering a balanced approach that many drivers find ideal for general racing and tuning.
