PETRONAS Tutela Brake Fluid Truck DOT Special is a brake fluid based on glycol ethers and boric esters, formulated for special and heavy-duty applications such as trucks and commercial vehicles. It meets FMVSS 116 DOT 4, IVECO 18-1820 (contractual technical reference no. I002.F99), SAE J1703, SAE J1704, ISO 4925 Class 4, CUNA NC 956-01, FIAT 9.55597 and ENSAYOS INTA - UNE 26-109-88 specifications. Typical properties include a dry boiling point of 265°C and a wet boiling point of 173°C, with passing results on SBR, EPDM and natural rubber compatibility tests, reflecting the high thermal resistance and elastomer compatibility expected of a heavy-duty DOT 4 fluid.
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 the fluid has taken up water.
IVECO 18-1820 — brake and clutch fluid
IVECO's standard for hydraulic brake and clutch-control fluid.Source
SAE J1703 — DOT 3 brake fluid
The SAE standard for glycol brake fluids at the DOT 3 level, defined by dry and wet boiling point.
SAE J1704 — DOT 4 brake fluid
The 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.
CUNA NC 956-01 — Italian lubricant classification
The CUNA classification — the Italian automotive standards commission — which numbers the categories of vehicle lubricants and fluids.
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.
UNE 26-109-88 — engine oil (Spain)
A Spanish national engine oil standard from the 1980s, with compliance testing historically carried out by INTA, the national aerospace technology institute.
