Monster Oil was founded by three professional trumpet players — Thomas Brown, Joel Baroody and Chris Lane — who collaborated with an aerospace lubricant firm to develop brass lubricants from the ground up. Products originally developed for NASA were reworked until they were perfect for brass instruments. The result is a line designed to clean, protect and lubricate simultaneously — not just keep valves moving but actively prevent the corrosion and wear that degrades instruments over time. Made in the USA. Endorsed by Ryan Anthony, Principal Trumpet of the Dallas Symphony, and Doc Severinsen.Monster Oil was founded by three professional trumpet players — Thomas Brown, Joel Baroody and Chris Lane — who collaborated with an aerospace lubricant firm to develop brass lubricants from the ground up.
