The vintage oil has a heavier viscosity that works well on older instruments with looser valves or larger horns such as tubas and euphoniums.

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 surface of the valves dries out quickly, making the action feel sticky or slow over time.

With Yamaha synthetic oils, the size and weight of the molecules are equal. This keeps the oil stable and consistent in even the most demanding situations, making your valves feel smooth for far longer.
