The Yamaha Valve Oil is a newly developed synthetic oil which provides more consistency than mineral-based oils to give a more superior performance regardless of the playing environment.
The Regular Oil consists of evenly sized molecules which means that the oil can evaporate much more smoothly and therefore guarantees a longer life with a very responsive action. This oil is designed for instruments with normal valve tolerances like student trumpets this oil is supplied as standard with all Yamaha Student Series instruments.
