BOSCH ESI6-32N Low Viscosity, Extended Life Brake Fluid - Compatible with All Vehicles Designed to Use DOT 3, DOT 4, and DOT 5.1 Brake Fluids; 1 Quart

[NEXT GENERATION FLUID] - Bosch ESI6 is a next generation brake fluid designed for today's modern braking systems and is the first fluid to simultaneously combine both low viscosity and high wet boiling point (365 Degrees Fahrenheit)

[EXTENDED SERVICE INTERVAL] - ESI6 is designed to last longer than traditional fluids for extended replacement intervals: 100% longer than DOT 3, 50% longer than DOT 4, and 10% longer than DOT 5.1 (with 30% lower viscosity)

[BACKWARD COMPATIBLE} - ESI6 is intended for use as a direct replacement for vehicles that specify DOT 3, DOT 4 or DOT 5.1 fluid which includes the majority of all brake systems launched since 1990

[REDUCES WEAR] - ESI6 delivers excellent lubricity properties to prevent brake system component wear and reduce noise; ESI6 is fully compatible with DOT 3, DOT 4, and DOT 5.1 fluids for top off but optimum performance is achieved with a full fluid change

[NOT DOT 5 COMPATIBLE] - ESI6 exceeds all DOT standards for DOT 3, DOT 4, and DOT 5.1 fluids but is NOT compatible with vehicles that require/use DOT 5 fluids - never use any fluid other than DOT 5 in DOT 5 systems

1 Quart (32 ounces) - When doing a full fluid change, multiple quarts will be necessary to properly flush the old fluid from the system and bleed the brake system after refilling with ESI6
