Dumonde Tech Break-In / Storage Oil is a precision-engineered, complex formula designed to optimize engine performance and longevity. As the first company to develop a specialized two-cycle break-in oil, Dumonde Tech ensures proper ring seating, work hardening, and impregnation of engine components with a protective matrix film—guarding against corrosion and wear during lean periods and storage.

Proper engine break-in is critical for both short- and long-term performance. Using a standard high-performance oil too early can prevent optimal ring seat and work hardening, leading to reduced engine life. Dumonde Tech’s break-in oil, combined with our proven procedure printed on every bottle, allows controlled temperatures and precise lubrication to maximize engine durability and performance.

Benefits:

• Measurable, proven performance gains

• Reduced engine failures and increased reliability

• Improved cooling efficiency

• Superior protection against corrosion and wear

• Trusted and recommended by legendary engine builders including Arlan Lehman (LED), Dave Moore Racing, and Tom Morgan Racing Engines
