Valve oil keeps piston valves moving, and the base, thickness and bottle design differ. Some are synthetic, one adds PTFE, and some are listed for slides and keys as well.
The six oils below come from Yamaha, MusicNomad, Denis Wick, Champion, Blue Juice and Al Cass. Facts come from each page, and performance claims are the makers’ own. We have not used these products ourselves.

Suits: all-round piston valve use. Strengths: a large bottle and a dropper top. Weaknesses: regular viscosity only. Skip it if you want a thinner oil.
