Reflecting the importance of the role of brake fluid in the braking system, the ISO-4925 standard created a new class 7 category to ensure fluids have higher wet and dry boiling points at a low viscosity. This provides more safety for motorists as well as a greater responsiveness and protection for ABS and ESP systems.

Bosch met this new standard four years before it became official with it ENV6 fluid which meets and surpasses this standard with a viscosity of ≤700mm²/s and a boiling point of ~ 270°.

The ENV range of Bosch brake fluids is increasingly being used as original equipment by vehicle manufacturers. The list of manufacturers can be found on the ENV packaging and includes: Volkswagen Group, General Motors, BMW, Stellantis and Ford. More recent approvals include Daimler and Volvo. 

The fluid comes in various convenient pack sizes which allow workshops to offer OE equivalent high performance fluids for their aftermarket customers. ENV6 also offers 50% extended maintenance intervals for drivers with 2 years/40,000km for DOT compared to 3 years/60,000km for ENV6. 

The shelf life of ENV6 is also twice that of Bosch Blue Brake Fluids at 60 months from the production date shown on the packaging. This allows fluid to be ordered in bulk. ENV6 is also a single fluid that covers 100% of synthetic brake fluid needs to cover most cars in a workshop. 

Bosch ENV6 brake fluid is available from stockists.
