- Mobil SHC Aware ST Series lubricants are high performance, emulsifying stern tube oils for marine stern tube systems that meet the U.S.
- Environmental Protection Agency (EPA) 2013 Vessel General Permit (VGP) guidelines for "environmentally acceptable lubricants".
- Mobil SHC Aware ST Series emulsifies readily with seawater to form a stable water-in-oil emulsion that is adhesive and an excellent lubricant.
- It provides effective rust protection in the presence of seawater and the lubricating film is resistant to water washing so that corrosion protection is maintained for extended periods under severe operating conditions.

Applications
Marine stern tube systems, fin stabilizers, and certain controllable pitch propeller systems where spills or leakage could result in adverse environment impact
In systems where readily biodegradable and minimally toxic fluids may be required
Marine and mobile equipment operating in environmentally sensitive areas
Circulation systems operating under mild to moderate service conditions
