Premium Plant-Based Synthetic Oil
The Monster Oil EcoPro Heavy Valve Oil is a 100% plant-based synthetic valve oil. This valve oil is designed for instruments whose valves have seen a lot of play and for those with large valve gaps that need some extra heft.
Monster Oil’s groundbreaking EcoPro line of lubricants is a plant-based, renewable synthetic oil that keeps up with, and even outperforms, most other oils on the market. The EcoPro oils act like other synthetic oils and are made to exacting standards with incredible consistency. Odorless and with no untoward interactions with other oils, the professionally tested EcoPro oils pose no risk of spoiling or going rancid.
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.
Made in the USA.
