FMVSS 116 DOT 4 — brake fluid
The US federal safety regulation defining the DOT brake fluid levels. DOT 4 demands a high boiling point both dry and after water uptake.
SAE J1704 — DOT 4 brake fluid
SAE standard for DOT 4 brake fluids, with a higher boiling point than DOT 3, particularly once the fluid has taken up water.
Brake fluid Class 4 — ISO 4925
The international standard for glycol brake fluids; class 4 matches the DOT 4 level, with a high boiling point both dry and wet.

Eni Brake Fluid DOT 4 Plus is a high-performance synthetic fluid, especially suited to cases where the brake system works under severe operating conditions. Its high boiling point lets it be used safely in demanding ambient conditions, or under prolonged braking that overheats the system. It resists contamination by external moisture — the cause of a falling boiling point and of vapour lock, the gas bubbles that form in the circuit and take the braking effect with them. Its viscosity has been adjusted so that the product also works at low ambient temperatures.
