Product Overview
PETRONAS Tutela 100 EP (SAE 90) is a premium, high-performance monograde gear lubricant formulated specifically to deliver extreme pressure (EP) protection and robust component durability
Comprehensive Benefits
Extended Component Lifespan: Formulated with active anti-wear, anti-pitting, and Extreme Pressure (EP) additives that minimize surface stress and wear under heavy mechanical loads
Thermal & Oxidation Resistance: Maintains performance integrity at high operating temperatures, resisting oil breakdown, oxidation, and harmful sludge build-up
Rust & Corrosion Prevention: Provides a protective barrier on metallic surfaces to safeguard gear systems against moisture-induced corrosion and rust
Optimized Load-Carrying Performance: Ensures uniform oil film strength under severe pressures, reducing metal-to-metal contact
