A complete line of lubricants for all industries, made in Houston, Texas, is offered by our brand. We use certified API and SAE formulas, combining base stocks from the Valero, ExxonMobil, Motiva, and Calumet refineries, with additives from Afton Chemical, Chevron Oronite, Infineum, and Lubrizol. All our products meet and exceed the latest specifications of the American Petroleum Institute (API), Society of Automotive Engineers (SAE), and the American Chemical Council.

Our SAE 75W-90 Synthetic Gear Oil, API GL-4, is formulated with synthetic base oils and specialty performance additives to provide improved high-temperature thermal and oxidative stability in a wide range of operating conditions. Specialty anti-scuffing additives and friction modifiers offer advanced protection and lubricity in extreme pressure conditions. Additionally, this oil is highly shear stable while also resisting rust, oxidation, foaming, and varnish.

Designed for use in all seasons, the U1P SAE 75W-90 Synthetic Gear Oil, API GL-4, exceeds the year-round, all-weather performance viscosity requirements of SAE J306 and the rigorous performance requirements of API GL-4. It is formulated to provide enhanced protection for gears and bearings, reducing premature wear and damage to these critical components in various types of machinery and equipment, helping to prevent gear scoring, spalling, and pitting.

The anti-friction formulation of this oil helps reduce operating temperatures in gearboxes and other applications, ensuring that critical components like gears and bearings operate within safe temperature ranges. This results in quieter, smoother operation, reducing transmission noise and protecting gear teeth. Additionally, the formulation is designed to optimize gearshift performance by reducing resistance and ensuring a smooth and efficient gear-shifting process.

The outstanding viscosity stability of this oil allows it to maintain performance, provide reliability, and offer robust protection against viscosity loss in extreme situations with severe operating conditions. The stable lubricating film is resistant and effective in preventing friction between moving parts.

In summary, this ADVANCED 75W-90 GL-4 FORMULA offers premium synthetic base oils for superior thermal stability and cleanliness, as well as special anti-scuffing and friction modifiers for advanced protection under extreme pressure. It meets SAE J306 viscosity requirements for year-round, all-weather performance and exceeds API GL-4 standards for automotive axle gears, maintaining stability in diverse conditions. The robust, stable lubrication film reduces wear for prolonged gear and bearing life, minimizes deposits, and extends the life of critical components, reducing maintenance costs. This formulation also maintains adequate lubrication in low and high temperatures, minimizes leakage for cleaner operations and reduced contamination risks, and includes a Limited Slip Differential additive package for enhanced performance.
