This means you can adapt your RC car's turning performance in minutes, achieving faster exit speeds and smoother cornering on varied track surfaces. The 50K weight oil sits in the mid-range of Traxxas's differential oil lineup, making it an excellent choice for general-purpose use across different driving conditions and vehicle platforms.
Supplied in a convenient 20cc bottle, the TRX5137 gives you enough differential oil for multiple applications and maintenance cycles. This product is essential for serious RC car UK enthusiasts who understand that performance tuning goes far beyond just upgrading motors and ESCs—it's about dialling in every aspect of your chassis setup. Stock your RC workshop with genuine Traxxas differential oil today and unlock the full potential of your vehicle's handling.
Key Features
- 50K Weight Formulation — This specific viscosity rating provides an ideal balance of limited slip action for most track conditions and vehicle types, allowing you to tune your differential's locking characteristics without needing to change mechanical components.
- 20cc Bottle Size — The convenient 20cc bottle provides enough oil for multiple differential refills and maintenance cycles, giving you flexibility to experiment with different weights or service multiple vehicles.
- Works Across Multiple Platforms — While originally designed for the Traxxas Revo, this differential oil is fully compatible with other Traxxas vehicles and can be used in other RC car platforms with gear-type differentials, making it a versatile addition to your RC toolkit.
- Performance Tuning Tool — By altering the limited slip capability through oil weight selection, you can directly enhance your vehicle's turning performance and achieve faster exit speeds from corners, giving you a competitive edge on the track.
- Genuine Traxxas Quality — Manufactured by Traxxas with consistent viscosity and performance characteristics, this oil integrates seamlessly with Traxxas differentials and maintains reliable operation across multiple seasons of use.
- Easy Application — The controlled-pour bottle design makes it simple to apply the correct amount of differential oil without mess or waste, ensuring you can maintain your RC car quickly and efficiently.
Technical Performance
The Traxxas Oil, Differential (50K wt) is engineered with a precise viscosity rating specifically chosen to provide optimal performance in modern RC car differentials. Differential oil weight directly affects how much your vehicle's limited slip differential will lock up under load, which in turn determines how your RC car behaves when cornering and accelerating out of turns. Lighter oils (like 30K weight) provide less locking action and smoother, more predictable handling characteristics suitable for high-grip surfaces and technical courses. Heavier oils (like 100K weight or higher) increase the locking action, giving you more aggressive turning and better traction out of corners, ideal for low-grip surfaces and speed-focused driving. The 50K weight formulation strikes a middle ground, offering versatility across varied track conditions and driving styles. This makes it an excellent default choice for RC car UK owners who want reliable performance without needing to stock multiple oil weights. The oil's viscosity is stable across temperature ranges typical of RC racing, ensuring consistent differential action whether you're racing indoors under controlled conditions or bashing outdoors in changing weather. Proper differential oil maintenance extends the life of your gear differential by reducing wear and friction between the internal gears, meaning you'll enjoy longer intervals between differential overhauls and rebuilds.

Frequently Asked Questions
- What is differential oil and why do I need it for my RC car? — Differential oil is a specially formulated lubricant that fills your RC car's differential housing. It lubricates the internal gears and pinions while simultaneously controlling how much your differential will lock up during cornering and acceleration. Different weights provide different amounts of limited slip action, which directly affects your vehicle's turning performance. By selecting the right oil weight for your track conditions, you can fine-tune your car's handling without any mechanical changes.
- Will the 50K weight work in my Traxxas vehicle? — The 50K weight is specifically designed for the Traxxas Revo and has been confirmed by users to work excellently in the E-Revo as well. It is also compatible with other Traxxas vehicles that feature gear-type differentials. However, always consult your vehicle's manual to confirm your specific model uses a fillable differential before applying this oil.
- How often should I change my differential oil? — This depends on your usage frequency and driving conditions. For regular weekend bashers, changing differential oil once or twice per season is typical. For serious racers and competitors, differential oil should be inspected and replaced more frequently, especially if you're changing weights to suit different track conditions. Always drain and replace oil if it appears discoloured or contains debris from gear wear.
- What's the difference between different differential oil weights? — Traxxas offers differential oils in various weights, each providing different amounts of limited slip action. Lighter weights (30K and below) provide minimal locking, creating a more predictable, drifty feel ideal for high-grip tracks. Medium weights like this 50K formulation offer balanced performance across varied conditions. Heavier weights (75K, 100K and above) provide maximum locking for aggressive turning and maximum traction, ideal for low-grip surfaces and offroad bashing. Your choice should depend on your track surface, driving style and vehicle setup.
- Can I use this oil in non-Traxxas RC cars? — While this oil is formulated for Traxxas differentials, many RC enthusiasts use Traxxas differential oils in other brands' vehicles with compatible gear-type differentials. Always check your vehicle's manual first to ensure compatibility, and ensure you understand your differential design before applying oil from a different manufacturer's product line.
- How much does 20cc of oil provide? — A 20cc bottle typically provides enough oil for 2-4 complete differential refills, depending on your vehicle's differential capacity. This gives you flexibility to experiment with different weights or to service multiple vehicles before needing to reorder.
