Business customers only. We sell wholesale, invoiced to registered companies.
FMVSS 116 — DOT 3 brake fluid
The US federal motor vehicle safety standard for glycol-based brake fluid, DOT 3 grade.
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.
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.
FCA 9.55597 — DOT 4 brake fluid
Fiat/FCA's specification for a synthetic DOT 4 brake and clutch fluid, exceeding FMVSS 116 DOT 4, ISO 4925 and SAE J1703/J1704.
Derived from the vehicle makers' approvals this product meets. Check the specification your vehicle's manual requires.

PETRONAS Tutela Brake Fluid DOT 4 is a premium quality performance hydraulic brake and clutch systems fluid, delivering optimised performance and component durability for today's vehicle braking systems. It is especially recommended for ABS, TCS and ESP/DSC systems. The fluid extends braking system life through enhanced corrosion protection for metal-based components, good thermal stability for consistent performance over the service life, effective lubricity to prevent squeak noise and improve reaction time, and good elastomer and rubber compatibility to prevent leaks and extend component life. It also delivers an outstanding driving experience through optimal pedal-stroke stability with no hysteresis across cold/hot/cold cycles, enhanced resistance to brake fade even in severe conditions thanks to high thermal resistance, good low-temperature fluidity for effective system reaction time, and a high dry boiling point to prevent vapour lock, together with a high wet boiling point for lasting braking efficiency and improved vehicle safety. It meets FMVSS No. 116 DOT 3/DOT 4, ISO 4925 Class 4, SAE J1703 and J1704 specifications, with Continental ATE, FCA 9.55597 DOT 4, IVECO 18-1820, MAT 3630, MS-90039, Nissan NES-M5 055 and Renault 41-02-001/-E performance-level references.
