If you want repeatable diff settings, the XRAY 359306 Premium Silicone Oil 6000cSt gives steady, tested viscosity tailored for RC car differentials. Produced in Europe, the batches are lab-verified so your tuning results stay consistent run after run.
The XRAY range uses a CST marker system to help you select the right fluid. The 6000cSt option suits drivers after firmer diff feel, helping manage traction and mid-corner stability across a variety of track surfaces.
Bottle details are aimed at efficient pit work: the square design reduces rollaway risk, the narrow nozzle allows fine metering, and the colour-coding plus clear markings make it quick to identify the correct viscosity during busy setup changes.
