Features
Synthetic Oil

In regular mineral oils the molecules aren’t an equal size or weight, making them evaporate at different rates. As smaller molecules evaporate faster, the smoothness dries out quickly, making the action feel sticky or slow over time. 

With Yamaha synthetic oils, the size and weight of the molecules are even. This keeps the oil stable and consistent, making your instrument's parts feel smooth for far longer.
