This state-of-the-art formula by Yamaha is much more consistent than other traditional valve oils. This gives the valves an much smoother and stable performance in a wide range of temperatures. The oil also helps lengthen the life of your instrument with its powerful corrosion inhibitor in the formula.
The "Light" viscosity is for instruments with extremely precise valve tolerances. It is especially designed for Professional horns in the Yamaha Xeno and Artist lines.
The "Regular" viscosity is a great all around oil for any instrument with pistons.
The "Vintage" viscosity is a thicker oil formulated for older instruments with looser valve tolerances. It is also great for instruments with longer pistons such as tuba and euphonium.
