Ep 80 Sub Apr 2026

Standard oils can shear or thin out when subjected to the high torque and shock loads found in marine reduction gears. EP 80 lubricants are formulated with sulfur-phosphorus additives that form a "sacrificial" chemical layer on metal surfaces. Under intense pressure, this layer protects gear teeth from welding together or scuffing, ensuring smooth power transfer even during rapid maneuvers. 2.

meet stringent military specifications (such as MIL-PRF-17331L) required for Navy vessels and submarines. These oils must maintain a high viscosity index, meaning they stay thick enough to protect gears at operating temperatures but fluid enough to flow instantly during a cold start in frigid waters. 3.

While "EP 80 SUB" could refer to a few things, it most commonly points to heavy-duty lubricants like the Chevron GST 2190 EP ISO 80 , which is specifically rated for military vessels and submarines. In a marine environment

: It separates readily from water, allowing moisture to be drained away rather than letting it circulate and cause rust.

In a marine environment, water ingress is an ever-present threat. A quality EP 80 lubricant is designed with:
