5W16 Break-In Oil Case 12x1 Quart

The 5W16 Break-In Oil Case 12x1 Quart by MAXIMA RACING OILS is a specialized lubricant designed specifically for the critical break-in period of newly rebuilt or manufactured engines. This oil is essential for protecting engine internals during the initial miles when components are settling into their final operating conditions. It is ideal for use in freshly bored and stroked builds, complete crate engines, or reconditioning seized motors.

Featuring a 5W viscosity rating at startup, this oil ensures rapid circulation to critical bearing surfaces during cold engine cranking, which is crucial for maintaining proper lubrication under tight machining tolerances. The 16-weight viscosity at operating temperature provides a protective film layer without excessive drag, supporting the break-in process effectively. MAXIMA's formulation includes anti-wear additives and rust inhibitors that protect fresh cylinder walls and bearing journals from corrosion.

High-performance builders, restoration shops, and engine reconditioning specialists will find this oil particularly beneficial during the first 500 to 1,000 miles of engine operation. It is specifically tailored for new and rebuilt engines, ensuring that they achieve optimal performance and longevity. This dedicated break-in oil is a crucial component for anyone looking to ensure the best possible start for their engine.
