Premium Valve Oil
The Monster Oil “Smoother” Valve Oil is a heavier synthetic valve oil perfect for keeping your worn-valved, vintage instruments operating smoothly and efficiently. Some players also love using the “Smoother” with low brass instruments such as Tuba or Euphonium.
Professional trumpet players Thomas Brown, Joel Baroody, and Chris Lane established and developed Monster Oil. Knowing exactly what was needed in a valve oil, they tested their products with some of the best brass musicians on all brass instruments.
