Maxima Performance Break-in Oil is specifically designed for breaking in engines with flat tappet camshafts, roller elements or where elevated levels of anti-wear additives are needed. High Zinc / Phosphorous formula is blended with highly refined, pure petroleum base stocks to provide optimum ring seal.


Not Recommended For Street Use. Maxima Performance Break-in Oil formula has elevated anti-wear additives designed to protect engines in extreme conditions. Elevated anti-wear additives may adversely impact emissions systems on vehicle.

For use in the break-in of high performance race engines, including Off-Road, Circle Track, Drag, etc.

Promotes ring seal and provides maximum protection for cams and all critical valve train components during initial break-in of flat tappet and roller cam engines.

Compatible with petroleum, semi-synthetic and fully synthetic motor oils.

Ideal for use in race engines, O.E.M. rebuilds and crate motors.

2X zinc formula reduces critical engine wear; complex 2X Zinc structure protects for an extended temperature range, outperforming conventional break-in oils. By combining two different zinc compounds, Performance Break-in Oil activates at lower temperatures and offers more protection at elevated temperatures.

Performance Break-in Oil is perfectly balanced and requires no other additives. Dyno tests show more efficiency in the break-in phase when using Maxima Performance Break-in Oil.
