One of its primary weaknesses is its tendency to absorb moisture from the air through the porous brake system components and the reservoir vent. Its viscosity is another defining trait, designed to remain stable across a range of temperatures to ensure consistent pedal feel and hydraulic pressure transmission within the braking circuit.
Mineral Oil Brake Fluid Vs Synthetic: Moisture, Performance, And Budget Considerations
Property Mineral Oil Fluid Glycol-Ether Fluid (DOT 4) Base Mineral Oil Polyalkylene Glycol Moisture Absorption Low High Typical Boiling Point (Dry) Approx. This absorbed moisture lowers the boiling point of the fluid and can lead to internal corrosion.
Furthermore, its lower cost makes it an attractive option for budget-conscious restoration projects or vehicles that are not subjected to extreme performance driving. Designed to maintain a stable viscosity in varying climate conditions.

This origin gives it a fundamentally different molecular structure compared to glycol-ether based fluids, which impacts how it interacts with seals, absorbs moisture, and handles temperature extremes. Compatibility with the rubber seals and hoses found in older vehicle designs.
