Industrial Lubricants and Greases
Conventional Gear Oils
Driveline designs are changing, and operating conditions are getting more and more severe. So, you need gear lubricants that keep pace, with exceptional load-carrying capability whenever extreme pressure and shock loads can be expected. Like the advance driveline gear oils developed by Sinclair, formulated to give you an effective balance of protection, toughness and endurance.
Thermal degradation protection.
Reductions in both wear and corrosion.
Better shear stability.
Sinclair gear oils are designed for use on-highway passenger cars, SUVs, light- and heavy-duty trucks, buses, and vans. Off-highway industries, such as construction, mining, quarrying and agriculture engines are also ideal for Sinclair Gear oils.
However, Sinclair Gear oils are not recommended/intended for applications requiring API GL-4 level performance or automatic, manual or semiautomatic transmissions for which engine oil or automatic transmission fluids are recommended. For more information, please consult your owner’s handbook for the specific OEM application requirements for your vehicle or equipment.
Formulated to Combat Friction and Wear
Our advanced formulation features a molecular bond that creates a shield designed to reduce friction and wear.
Holds Up Even Under Extremes
Not even the harshest cold or most punishing heat can keep Sinclair Gear Oils from outstanding protection against pressure, power density, micropitting or oxidation, shrinking sump sizes or separation of air and water.
Sinclair Conventional Gear Oils: Performance You'll Notice
