Technical Information and Specifications

Restoreplus Gear Oil 90W is taken as reference, and the common technical values of substitutes from this segment are as follows:

• Viscosity Stability: It is at SAE 90 grade. Provides ideal oil film thickness at operating temperatures to minimize Wear and Heating of gear surfaces.

• EP (Extreme Pressure) Additives: Forms a protective chemical layer between gear teeth under heavy load and sudden torque changes, preventing Pitting and gear scores.

• API Standards: Generally available in the market as API GL-4 (for synchronized manual transmissions) or API GL-5 (for heavy-duty hypoid differentials) versions.

• Oxidation Resistance: Contains additives that prevent chemical breakdown of the oil due to heat during prolonged operation and Sludge/Deposit Formation.

• Seal Compatibility: Fully compatible with gearbox seals and gaskets; maintains Seal Flexibility to prevent leaks.

• Rust and Corrosion Protection: Significantly increases Part Life by protecting metal surfaces inside the gearbox from moisture and oxidation.

• Foam Control: Prevents foaming of the oil at high gear rotation speeds, ensuring the lubrication function Continues Without Interruption.

• Yellow Metal Protection: GL-4 products include special Passivating components that do not harm bronze and brass parts (syncromes) in the transmission.

Usage Area: This product is safely used in differentials of passenger and commercial vehicles, hypoid gear systems, manual transmissions, powertrains of agricultural equipment, and general industrial gear boxes.
