Specially formulated Yamaha rotor spindle oil gives noiseless operation of rotor spindles in rotary valve instruments. The fast action and smooth response of Yamaha synthetic oils last longer than traditional mineral-based oils while staying consistent and stable even in different temperatures. 

The special synthetic formulation ensures that the size of the molecules in each viscosity is consistent and provides the optimal balance of duration and performance.
