Shell Omala S2 G oils are high quality extreme-pressure oils designed primarily for the lubrication of heavy duty industrial gears.  Their high load 
carrying capacity and anti-friction characteristics combine to offer superior performance in gears.

• Long oil life – Maintenance saving
Shell Omala S2 G oils are formulated to resist thermal and
chemical breakdown throughout the maintenance interval. They withstand high thermal loading and resist the formation of sludge to provide extended oil life capability, even with bulk oil temperatures of up to 100°C in certain applications.
• Excellent wear & corrosion protection
Excellent load carrying capacity reduces gear tooth and
bearing wear on both steel and bronze components. Shell Omala S2 G has excellent corrosion protection,
protecting both steel and bronze components, even in the
presence of contamination by water and solids.
• Maintaining system efficiency
Shell Omala S2 G oils have excellent water separation
properties, such that excess water can be drained easily from lubrication systems to help extend the life of the gears and ensure efficient lubrication of the contact areas.
Water can greatly accelerate surface fatigue of gears and bearings as well as promoting ferrous corrosion on internal surfaces.  Water contamination should therefore be avoided or removed as quickly as possible after the occurrence.

• Enclosed industrial gear systems
Shell Omala S2 G oils are formulated using an effective
sulphur-phosphorus additive system to provide an extreme pressure performance which allow trouble-free application in most enclosed industrial gearboxes using steel spur and helical gears. 
• Highly loaded gears
Shell Omala S2 G oils have an effective full extreme pressure
(EP) additive system allowing them to be used in highly-loaded gear systems.
• Other applications
Shell Omala S2 G oils are suitable for lubrication of bearings
and other components in circulating and splash-lubricated systems.
For highly-loaded worm drives the Shell Omala “ W” series oils are recommended.
For automotive hypoid gears, the appropriate Shell Spirax Oil should be used.
