Wear Protection

Protecting machine gears from wear and corrosion is important for prolonging asset life and preventing breakdowns. The Shell Omala range of gear oils offers protection across a wide range of applications. It includes Shell’s latest synthetic oils such as Shell Omala S4 GX, which offers exceptional long-life performance under extreme loads and temperatures.

Oil Life

Customers using Shell’s standard products, such as Shell Omala S2 G, are extending oil-drain intervals by up to 200% for some applications. Customers are trading up to synthetic oils, such as Shell Omala S4 GX, for even longer oil life and other benefits.

Real-world Value Delivery

Users of Shell Omala oils are benefiting from proven, robust and reliable lubrication that adds value to their operations. For instance, by switching to Shell Omala S4 GX, some customers are

  • increasing equipment protection: one customer reports virtually eliminating gearbox failures 
  • extending oil-drain intervals. Some equipment manufacturers approve Shell Omala S4 GX for four-year drain intervals, and some customers have extended their oil-drain intervals by up to five times.

Shell Naturelle S4 Gear Fluid 68, 100 and 150

Prematurely worn components can mean additional maintenance costs and reduced equipment availability. Shell Naturelle S4 Gear Fluid can help to lower maintenance costs by offering outstanding anti-wear and load-carrying performance through their high-quality, synthetic ester base fluid and advanced non-toxic anti-wear additives.

Longer Service Life

Fully saturated esters ensure excellent resistance to oxidation and hydrolysis while offering high-temperature thermal stability. Shell Naturelle S4 Gear Fluid offers the potential to extend oil service life compared with conventional mineral gear oils.

Load Carrying and Wear Protection 

Shell Naturelle S4 Gear Fluid is formulated to have excellent loadcarrying capacity and anti-scuffing performance. Advanced non-toxic additives provide protection over a wide range of conditions and ensure long component life, even under shock-loading conditions. All Shell Naturelle S4 Gear Fluid grades pass the FZG load test above load stage 13 according to ISO 14635 A20.
