Customer Questions & Answers
-
Question:
What is ARRMA 20 Million CST Diff Fluid used for?
Answer: ARRMA 20 Million CST Diff Fluid is primarily designed for use in remote-controlled cars and vehicles, enhancing the performance of the differential system. This fluid offers a high viscosity, providing better traction and stability, especially in high-performance racing scenarios. When installed, it allows for smoother cornering and controlled power delivery to the wheels, making it ideal for off-road and competitive racing contexts. -
Question:
How do I know if I need to change my diff fluid?
Answer: If you've noticed decreased performance in cornering stability or increased wear in your RC vehicle, it may be time to check or change your diff fluid. Additionally, if your car exhibits jerky movements or uneven power distribution, this is an indication that the fluid’s properties may have degraded. Regular maintenance checks, especially after a few racing sessions, can help you determine its condition. -
Question:
Can I use ARRMA 20 Million CST Diff Fluid in any RC vehicle?
Answer: While ARRMA 20 Million CST Diff Fluid is compatible with many RC vehicles, it’s recommended specifically for those designed by ARRMA. Using it in vehicles that require a different viscosity could lead to performance issues. Always consult your vehicle's manual or manufacturer’s guidelines to ensure compatibility, helping to optimize performance based on their specific designs. -
Question:
How is the viscosity of 20 Million CST diff fluid beneficial?
Answer: The 20 Million CST viscosity rating means the fluid is thick enough to provide strong resistance against the internal gears of the differential, promoting effective power transfer and better traction. In racing conditions, this prevents slip and allows for better control when navigating sharp turns. This is particularly advantageous in varying track conditions, including damp or slippery surfaces. -
Question:
Does ARRMA 20 Million CST Diff Fluid come in different sizes?
Answer: The ARRMA 20 Million CST Diff Fluid is typically sold in a 20mL container, which is adequate for multiple applications in model vehicles. While it's common to find this product in various viscosities, the 20mL size is popular due to its convenience for hobbyists and racers who perform regular maintenance without overstocking. -
Question:
How do I apply the diff fluid to my RC vehicle?
Answer: To apply ARRMA 20 Million CST Diff Fluid, first disassemble the differential unit of your RC car. Clean all components thoroughly to remove any old fluid residues. Next, carefully fill the differential housing with the new fluid using a dropper or syringe until it reaches the appropriate level. Reassemble the unit, ensuring all seals are tight to prevent leaks, and test its performance on your next run. -
Question:
Is this diff fluid suitable for different terrains?
Answer: Yes, ARRMA 20 Million CST Diff Fluid is versatile and can be used across various terrains. Its formulation is designed to provide consistent performance whether you’re negotiating rocky trails, muddy paths, or smooth racetracks. The fluid’s viscosity aids in maintaining control and stability, making it a great option for mixed-terrain racing enthusiasts. -
Question:
Can I mix this diff fluid with other types of fluid?
Answer: It’s generally not advisable to mix ARRMA 20 Million CST Diff Fluid with other types of diff fluids, as this can alter its performance characteristics. Mixing fluids with differing viscosities may lead to unpredictable handling and reduced overall performance. For the best results, always use this fluid alone as per the manufacturer’s recommendations. -
Question:
What are the performance benefits of using high viscosity diff fluids like this one?
Answer: Using high viscosity diff fluids like the ARRMA 20 Million CST improves the responsiveness and handling of your RC vehicle. This level of fluid thickens the differential, which helps prevent slipping and allows for precise traction control. As a result, you’ll experience enhanced cornering speeds and stability, allowing you to navigate challenging tracks with greater ease. -
Question:
Where can I buy ARRMA 20 Million CST Diff Fluid (20mL), ARA850027?
Answer: You can purchase ARRMA 20 Million CST Diff Fluid (20mL), ARA850027, from Ubuy in Guernsey. Ubuy offers a reliable platform for purchasing RC vehicle accessories, ensuring you have access to quality products to enhance your RC racing experience.
ARRMA Oil & Lubricants ARA850027 Editorial Review
