Naturelle S4 Gear Fluid 68, 100, 150
Shell Naturelle S4 Gear Fluid 68 100 150, Ecolabel of the European Union, US-EPA-VGP-compliant
Biodegradable special fluid for gears and bearings Shell Naturelle S4 Gear Fluid is a highly developed synthetic fluid for applications in gears with thrusters and drives. Shell Naturelle S4 Gear Fluid is made from fully saturated esters, formulated for superior load-bearing capacity, while being readily biodegradable with little ecotoxicity. Shell Naturelle S4 Gear Fluid is an "Environmentally Acceptable Lubricant (EAL)" according to the definition of the "US EPA 2013 Vessel General Permit".

Compatibility and miscibility
Miscibility with other oils
Shell Naturelle S4 Gear Fluids can be mixed with mineral oils. To ensure the environmental properties and performance of Shell Naturelle S4 Gear Fluid, the system should be drained and thoroughly flushed when changing fluids.
If the system was previously used with mineral oil, residues may have formed. Due to the surface wetting properties of the EAL, these can loosen and collect in the system filter. The filters should therefore be checked regularly, especially after they have been re-oiled.
In order to check the usability of the new fluid, it is strongly recommended to take an oil sample after the oil change and have it analyzed by Shell Rapid Lubricants Analysis.
Compatibility with surrounding materials
Shell Naturelle S4 Gear Fluid is compatible with sealing materials and paints that are normally suitable for use with conventional mineral oils. However, the recommendation of the OEM should be obtained, who will confirm the suitability of Shell Naturelle S4 Gear Fluid for your application.
· High viscosity index
Provides a shear-stable lubricant to protect components over a wide temperature range.
· Extended service intervals
Fully saturated esters ensure excellent oxidation stability and hydrolysis stability, as well as high thermal stability. Shell Naturelle S4 Gear Fluid offers the option of extended service intervals compared to gear oils based on mineral oil.
· Wear protection and load-bearing capacity
Shell Naturelle S4 Gear Fluid has been formulated for excellent load-bearing capacity and high protection against seizure damage. Advanced, non-toxic additives protect over a wide range of operating conditions and ensure long component life, even under shock loads.
· Support of a consistently high system efficiency
Shell Naturelle S4 Gear Fluid has excellent water release properties. Excess water can be easily drained from the lubrication system; this supports the extension of the component service life and ensures efficient lubrication at contact points.
· Easily biodegradable
Shell Naturelle S4 Gear Fluid is more than 60% biodegraded in the OECD 301 biodegradation test after 28 days.
· Low environmental toxicity
Reduced impact of accidental release into the environment. Shell Naturelle S4 Gear Fluid is classified as "not harmful" for bacteria, algae, freshwater and marine invertebrates, and fish when tested as "water accomodated fractions (WAFs)" according to the OECD and EPA tests Guidelines. Recommended for use in environmentally sensitive areas
Shell Naturelle S4 Gear Fluid is USA EPA 2013
Vessel General Permit is classified as an Environmentally Acceptable Lubricant and offers a reduction in the risk of marine use compared to conventional mineral oil. It has a reduced effect on the environment in the event of a leak or accidental release. It is in particular suitable for use in ecologically sensitive areas
