Team Corally Diff Syrup Ultra Pure Silicone Oil 1000000 cSt 60ml C-81620

Overview

The Corally Diff Syrup Ultra Pure Silicone 1000000 CPS 60ml (C-81620) is a premium differential oil designed for RC enthusiasts across the UK who demand the highest performance from their RC cars and trucks. Whether you're running a competitive 1/10 scale buggy, a high-performance 1/8 truggy, or any other RC vehicle type, maintaining your differentials with the correct silicone oil is essential to ensuring smooth, predictable handling and longevity of your drivetrain. This ultra-pure silicone formulation delivers exactly what serious RC racers and bashers need: consistent viscosity, reliable performance, and a product you can trust.

Differential oils are a critical but often overlooked component in RC car setup and maintenance. The differential is the component that allows your RC vehicle's wheels to rotate at different speeds when cornering, which is essential for stable handling and tire grip. Without the correct oil, your differential can either be too loose (causing slippage and unpredictable handling) or too stiff (causing binding and reduced steering response). The Corally Diff Syrup range offers multiple viscosity options so you can fine-tune your RC car's performance to match your driving style, track conditions, and vehicle setup.

This particular variant comes in the thickest option available at 1000000 cSt (centistokes), making it ideal for drivers who need maximum differential lock and resistance, perfect for high-speed racing, competitive events, or driving conditions that demand ultimate stability and control. With 60ml of product in each bottle, you'll have enough to service multiple vehicles or make multiple adjustments to dial in your RC car UK setup perfectly.

Key Features

• Ultra Pure Silicone Formula — This is 100% pure silicone oil, meaning there are no additives, fillers, or contaminants that could affect performance or cause unpredictable behaviour in your differential. Pure silicone ensures consistent viscosity across temperature ranges and provides reliable performance lap after lap.
• 1000000 cSt Viscosity — This is the thickest viscosity grade in the Corally Diff Syrup range, providing maximum differential lock and resistance to slippage. This heavy-duty formulation is ideal for high-speed racing, competition-level driving, or any situation where you need maximum drivetrain control and predictable handling characteristics.
• Precise Viscosity Control — Unlike generic oils, the Corally Diff Syrup range uses standardised CST (centistoke) measurements, allowing you to select the exact viscosity your RC car needs. This level of precision is essential for competitive RC driving where even small adjustments can impact lap times and handling feel.
• 60ml Generous Bottle Size — Each bottle contains 60ml of product, providing ample quantity for multiple differential servicing sessions or to make repeated adjustments as you dial in your RC vehicle's perfect setup. This size is practical for both casual hobbyists and serious competitors who maintain multiple RC cars.
• Professional-Grade Quality — Corally is a trusted brand among RC professionals and serious enthusiasts worldwide. This differential oil meets the demanding standards expected by competition-level drivers and is formulated to deliver consistent, repeatable results every time you use it.
• Easy Application — The 60ml bottle is designed for convenient pouring and application directly into your RC vehicle's differential. No specialised tools or equipment required—simply remove your diff cover, drain the old oil if necessary, and apply the new Corally Diff Syrup to achieve your desired setup.

Technical Performance

The Corally Diff Syrup Ultra Pure Silicone 1000000 CPS represents the pinnacle of differential oil formulation for RC cars and trucks. At 1,000,000 centistokes, this is an extremely thick oil designed for maximum differential lock and control. The viscosity measurement (cSt) is the industry standard for measuring fluid thickness; higher numbers mean thicker oils that provide more resistance and lock in the differential. This extreme thickness makes the 1000000 cPS variant ideal for high-speed racing where you need maximum stability, for drivers with aggressive steering inputs, or for track conditions that benefit from a locked differential. The 100% pure silicone construction means you're not dealing with any synthetic blends or additives that could degrade over time or cause unpredictable performance variations. Professional RC drivers appreciate the consistency that pure silicone offers—each application delivers the same performance characteristics, allowing you to build confidence in your RC vehicle's handling and make precise adjustments to your setup. The material engineering behind this product ensures that the viscosity remains stable across the temperature ranges typically encountered during RC driving, whether you're running your RC buggy indoors in a climate-controlled environment or racing outdoors in variable UK weather conditions.

Frequently Asked Questions

• What is differential oil and why do I need it for my RC car? — The differential in your RC vehicle is a precision component that allows the wheels to rotate at different speeds during cornering, which is essential for smooth handling and grip. Differential oil lubricates this mechanism and provides resistance to slippage. Without the correct oil, your RC car's handling will feel unpredictable and your drivetrain will wear prematurely. The Corally Diff Syrup range allows you to select the exact viscosity your vehicle needs for optimal performance.
• What does 1000000 cSt mean, and is this the right viscosity for my RC car? — cSt stands for centistokes, which is the standard measurement of fluid viscosity. 1000000 cSt is the thickest option available in the Corally Diff Syrup range. This extreme thickness provides maximum differential lock and resistance, making it ideal for high-speed racing, competitive driving, or situations where you need maximum stability and drivetrain control. If you're unsure whether this is the right viscosity for your specific RC car or driving style, consult your vehicle's manual or speak to experienced RC enthusiasts who use similar vehicles.
• Can I use this oil in any RC car or truck? — This differential oil is designed for use in any RC vehicle that has a serviceable differential, including RC buggies, RC trucks, RC truggy vehicles, and RC scalers. The 60ml bottle size makes it practical for servicing one differential or making multiple adjustments across different vehicles. Always check your RC vehicle's manual to confirm compatibility and the recommended viscosity range before application.
• How much oil do I need for my differential? — The amount of oil needed varies depending on your specific RC vehicle's differential capacity. Typically, you'll only need a few drops to a small amount for each differential service. The 60ml bottle provides ample quantity for multiple servicing sessions or repeated adjustments, making it an economical choice even if you're only servicing a single vehicle.
• Is this suitable for beginners? — Whilst differential oil adjustment is a straightforward process, it's most beneficial for drivers who understand how drivetrain setup affects RC car handling. Beginners can certainly use this product, but they may benefit from learning about viscosity options and how thicker oils affect differential lock and steering response. The Corally Diff Syrup range's standardised CST measurements make it accessible even to newcomers who want to experiment with their setup.
• What is the difference between 1000000 cSt and other viscosity grades? — The Corally Diff Syrup range offers multiple viscosity options, each suited to different driving styles and conditions. 1000000 cSt is the thickest available, providing maximum lock and resistance. Thinner oils (lower cSt numbers) provide less lock and more differential slippage, offering a looser, more drifty feel. Thicker oils like this one provide tight, locked differentials ideal for racing and high-speed driving. Your choice depends on your RC car type, track conditions, driving style, and personal preference for handling feel.
