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.
