The Yokomo YOKCSDOT2 is a silicone-based oil specially blended for gear-type differentials used in R/C models. As a tuning product, it changes internal slip to influence how power moves between wheels and how the car behaves mid-corner on 1/10 on-road and touring chassis.
Installation is straightforward: open the diff, drain existing fluid, and fill with the specified amount of the super flex oil to the gear mesh and cavity. With a softer viscosity, expect smoother, more gradual locking compared with higher weight oils.
Tuning advice: softer oils often help turn-in and grip on slippery tracks but can reduce the degree of lock under strong acceleration. Make small adjustments and evaluate on the circuit to dial in the right feel. Also inspect seals and monitor for leaks after refilling to ensure predictable performance.
