The Yokomo YOKCSDOT1 is a Dot 1 silicone differential oil created for RC-scale gear differentials. It is aimed at 1/10 scale electric on-road and touring chassis that require subtle differential behaviour and enhanced low-speed traction. Use this solely as a tuning fluid for model differentials.
In use, Dot 1 lowers internal drag and permits smoother engagement during low-torque conditions, assisting with corner entry and traction on lower-grip tracks. It produces faster internal recovery than heavier oils, helping steering responsiveness.
To install, drain the existing oil, clean internals if necessary, refill to the manufacturer's recommended volume for your diff, and allow a short run-in to stabilise behaviour before final setup adjustments.
