MOBIL SHC AWARE GEAR 68

U.S. EPA 2013 Vessel General Permit Compliant Gear Oil

Product Description

Mobil SHC Aware™ Gear Series are a range of high performance, anti-wear gear oils for use in marine applications and meet the U.S. Environmental Protection Agency (EPA) 2013 Vessel General Permit (VGP) guidelines for “environmentally acceptable lubricants”. They provide excellent wear protection for gears and bearings and safeguard equipment from rust and corrosion. They also possess outstanding oxidation properties, which help to extend oil life, and offer a wide operating temperature range and excellent low temperature start-up. Mobil SHC Aware Gear Series demonstrate excellent air release properties versus typical mineral gear oils, resulting in less air entrainment and protection from cavitation. Furthermore, their excellent seal compatibility helps to minimize leaks.

Features and Benefits

• Meets US EPA 2013 Vessel General Permit requirements for environmentally acceptable lubricants
• Outstanding load-carrying and anti-wear properties which protects system components against micropitting and scuffing and helps provide long equipment life
• Shear stable high viscosity index help sustain component protection over a wide temperature
• Excellent resistance to high temperatures degradation
• Very good demulsibility and resistance to rust and corrosion

Applications

• Marine controllable pitch propeller and thruster applications
• Suitable for enclosed gear drives including steel-on-steel spur, helical and bevel designs
• In systems where readily biodegradable and minimally toxic fluids may be required
• Marine and mobile equipment operating in environmentally sensitive areas
