Yokomo YOKCS7500 Super Blend Diff Oil for Electric RCs 30cc  [YOKCS7500]

Precision Silicone Differential Oil

This is an RC-scale gear differential oil sold in a 30cc bottle and identified by model Yokomo YOKCS7500. It is blended as a silicone super mix intended for use inside gear-type differentials fitted to electric radio-controlled models.

Purpose: apply this oil to influence how a gear differential transfers torque and permits slip under load, which affects handling balance and drivetrain response without changing hardware. The note explains the tuning purpose rather than claiming specific performance improvements.

Application notes: when refilling or topping a gear differential, clean all working parts and seals, maintain a consistent fill level, and test incremental adjustments on-track to evaluate effects. Because fluids interact with diff internals and gearing, make only small step changes between runs and log settings.

Compatibility: made for general RC gear differentials where a silicone-based blend is appropriate. Do not assume compatibility with non-gear differentials or brand-specific sealed units without checking the service recommendations for those assemblies.
