PETRONAS Tutela Axle 300 SAE 85W-140

Heavy-Duty Gear Lubricant & Final Drive Fluid

Executive Summary
PETRONAS Tutela Axle 300 SAE 85W-140 is specially formulated to operate under severe mechanical strain and high thermal conditions. Designed primarily for commercial, agricultural, industrial, and heavy-duty transport equipment, it meets the requirements of API GL-5 hypoid gear applications.

Deep-Dive Technical Capabilities

• Hypoid Gear Protection: Hypoid differentials experience sliding contact and extreme shock loads. The extreme pressure (EP) additives in Tutela Axle 300 form a sacrificial protective film on metal surfaces, preventing tooth scuffing, micro-pitting, and surface wear under peak torque.

• Viscometric Performance: With a high Kinematic Viscosity of 359 cSt at 40°C and 26.4 cSt at 100°C, this heavy-grade 85W-140 fluid maintains a robust oil film thick enough to separate gear teeth even under high heat and continuous load.

• Low-Temperature Fluidity: Despite its high viscosity profile, it achieves a Brookfield Viscosity of 90,000 mPa.s at -12°C and a Pour Point of -18°C, ensuring lubricant circulation during cold startups.

• Thermal Oxidation Defense: High gear temperatures often lead to oil thickening and varnish. The thermal stability of this fluid minimizes oxidation, maintaining clean gearboxes and seal integrity over standard service intervals.

Handling, Safety & Storage Guidelines

• Skin Contact: Prolonged exposure may cause mild irritation; wash thoroughly with soap and water immediately after handling.

• Environmental Care: Do not dispose of used fluid into sewers, waterways, or soil. Dispose of bulk containers via licensed waste management services.

• Storage Recommendations: Keep drum barrels sealed in a dry, sheltered location away from direct sunlight and extreme thermal fluctuations to preserve additive stability.
