Overview
The Corally Diff Syrup Ultra Pure Silicone 500000 CPS 60ml (C-81610) is a professional-grade differential oil designed specifically for RC car enthusiasts in the UK who demand precision tuning and optimal performance from their vehicles. Whether you're a competitive racer fine-tuning your RC buggy or a weekend basher looking to maintain your RC car's differentials, this ultra-pure silicone oil delivers the consistency and quality needed to keep your model running smoothly. The 500000 centiStoke viscosity rating makes this a thick, heavy-duty differential fluid ideal for high-speed driving, aggressive cornering, and demanding terrain where differential performance is critical to lap times and handling characteristics.
Corally is renowned in the RC hobby community for manufacturing premium maintenance products that meet the exacting standards of professional competitors and dedicated hobbyists alike. This differential syrup represents the pinnacle of their quality control, formulated as 100% pure silicone oil with absolutely no additives or contaminants that could affect your differential's responsiveness. The 60ml bottle provides enough fluid to service multiple differentials or to keep on hand for regular maintenance intervals throughout the racing season. For any RC car UK enthusiast serious about getting the most from their vehicle, this is a product that belongs in your maintenance kit.
At 500000 cSt viscosity, this is a premium heavy-weight differential oil that provides excellent damping characteristics and smooth power delivery through the differential gears. The ultra-pure formulation ensures consistent performance lap after lap, allowing you to make precise tuning adjustments knowing the oil itself isn't introducing variables into your setup. This level of purity is essential for competitive racing where every millisecond counts and where differential behaviour directly impacts acceleration, cornering speed, and overall vehicle handling on the circuit or off-road course.
Key Features
- 500000 cSt Viscosity Rating — This extremely high viscosity makes the oil ideal for heavy-duty differential work, providing superior damping and control during aggressive acceleration and high-speed cornering manoeuvres that would overwhelm lighter oils.
- 100% Pure Silicone Oil — The formulation contains absolutely no additives, contaminants, or water content that could compromise differential performance, ensuring every drop delivers consistent tuning characteristics.
- 60ml Bottle Size — The 60ml container provides ample fluid for servicing multiple differentials or maintaining several RC cars throughout a season without waste or the need for frequent reordering.
- Ultra-Pure Formulation — Professional-grade purity ensures that the oil performs identically from the first application to the last drop, eliminating variables that could affect your car's handling between maintenance intervals.
- Professional-Grade Quality — Manufactured by Corally, a brand trusted by competitive RC racers and serious hobbyists across Europe, this product meets the rigorous demands of both circuit racing and off-road competition.
- Barcode Verified Authenticity — Each bottle carries barcode 8718057177430, allowing you to verify you're purchasing genuine Corally product and not counterfeit imitations that could damage your differentials.
Technical Performance
The Corally Diff Syrup Ultra Pure Silicone represents a pinnacle of differential oil engineering for RC cars in the UK market. At 500000 centiStokes, this is one of the heaviest-weight differential oils available, designed for racers and enthusiasts who need maximum damping and control in their differential gearing systems. The ultra-pure silicone formulation means there are no additives, no water content, and no contaminants that could affect performance consistency or introduce unpredictable variables into your vehicle's handling characteristics. This purity is particularly important in competitive environments where precise tuning requires absolute consistency between service intervals. The oil's thick consistency provides excellent power transfer through the differential gears whilst simultaneously damping aggressive gear engagement, making it particularly suited to high-powered brushless RC buggies, trucks, and competition vehicles. The 60ml bottle format is ideal for UK RC enthusiasts who maintain multiple vehicles or who service their differentials regularly throughout a competitive season. Material compatibility is assured with all standard RC differential components, and the pure silicone base ensures no degradation or separation even under extreme driving conditions. For drivers seeking the ultimate in differential tuning precision, this represents professional-grade maintenance fluid that delivers measurable improvements in handling, consistency, and overall vehicle performance.

Frequently Asked Questions
- What viscosity should I use for my RC car differential? — Differential oil viscosity depends on your driving style and track conditions. The 500000 cSt viscosity in this Corally product is a heavy-weight option suited to high-speed racing, aggressive cornering, and competitive environments where maximum damping is beneficial. Lighter oils (lower cSt ratings) provide looser, more responsive differentials for technical tracks, whilst heavier oils like this 500000 cSt option provide more locked-up behaviour and control for open, flowing circuits or high-speed off-road courses.
- Is this suitable for beginners? — This product is best suited to experienced RC enthusiasts and competitive racers rather than absolute beginners. The 500000 cSt viscosity is a heavy-weight formula that provides significant damping; beginners may find medium-weight options (50000-100000 cSt) easier to tune with. However, if you're building a high-performance RC buggy or truck and want professional-grade maintenance fluid, this Corally product is an excellent choice regardless of experience level.
- How much differential oil do I need? — The 60ml bottle provided should be sufficient to service multiple differentials or maintain several RC cars throughout a season. Most RC car differentials require only 2-4ml per service, meaning a single 60ml bottle could service 15-30 differentials depending on fill quantity. For UK RC enthusiasts maintaining a fleet of vehicles, this represents excellent value and ensures you always have fresh oil on hand.
- Will this work with all RC car brands? — Yes, Corally Diff Syrup Ultra Pure Silicone is a universal differential oil compatible with all major RC car brands including Traxxas, ARRMA, Losi, Associated, Team C, Kyosho, and any other manufacturer using standard differential designs. The pure silicone formulation is universally compatible and won't damage any standard RC differential components.
- Why is pure silicone oil better than alternatives? — Pure silicone oil provides consistent viscosity across temperature ranges and doesn't contain additives or water that could affect performance or cause differential damage over time. The Corally ultra-pure formulation means every application delivers identical tuning characteristics, critical for competitive racing where consistency is essential.
- How do I apply this to my differential? — Differential oil is typically applied using a small syringe or applicator bottle (sold separately) directly into the differential housing through the filler hole. Consult your RC car's manual for specific fill quantities and procedures. Most applications require only a small amount of oil to achieve the desired damping effect.
