Frequently Asked Questions

• What is 55Wt silicone oil used for in RC cars? — Silicone oil in 55-weight specification is primarily used as shock oil and differential oil in RC cars, controlling the damping and performance of your suspension system and differential. By changing the weight (viscosity) of the oil, you can adjust how quickly your shocks compress and rebound, and how your differential behaves under load—heavier oils create more damping and slower response, while lighter oils allow faster movement. This 55Wt rating is ideal for general-purpose tuning on most RC vehicles.
• How does this oil compare to other brands available in the UK? — The Fastrax Racing Pure Silicone Oil 55Wt has been developed over 12 months and tested by Europe's leading drivers in conditions ranging from Spanish heat to UK rain. Drivers testing this oil commented that they had never encountered oils offering as much consistency and smooth progression through the range as Fastrax oils, making this oil stand out from competitors in terms of reliable, predictable performance.
• Will this oil work in my RC buggy, truck, or crawler? — Yes, this 55Wt oil is suitable for use as shock oil and differential oil in virtually all standard RC vehicles including buggies, trucks, crawlers, and other platforms commonly used in the UK RC hobby. The 55-weight specification makes it an ideal choice for general-purpose applications across most RC car types.
• How often should I change my shock and differential oil? — The frequency of oil changes depends on how much you drive and the conditions you drive in, but as a general rule, competitive drivers change their oil regularly during race seasons to maintain optimal performance. The easy-pour lid design of this Fastrax oil makes changes quick and straightforward, so you can maintain your RC car's setup easily.
• What does the 650 cSt viscosity rating mean? — Viscosity is measured in centistokes (cSt), a unit that describes how thick or thin the oil is. A 650 cSt viscosity is considered medium weight, suitable for most shock and differential applications on standard RC cars, providing a good balance between responsive damping and effective suspension control.
• Is this suitable for beginners? — While this is a professional-grade oil developed for competitive drivers, it is perfectly suitable for RC hobbyists of any experience level who want to tune their suspension properly. The 55Wt rating is one of the most commonly used weights, making it an excellent choice whether you're just starting to understand suspension tuning or you're an experienced competitor.
• How much oil is in each bottle? — The product listing indicates this is a single bottle of shock oil, though the exact volume in millilitres is not specified in the available product information. For most RC applications, a single bottle provides sufficient oil for multiple shock and differential refills.
