AMSOIL Industrial EP Series-S 680 Gear Oil (formerly known as Syn Tech EP+ 680) is engineered to provide maximum resistance to scuffing wear and micropitting fatigue on industrial gears and bearings operating under extreme pressures and shock loads. It resists thermal and mechanical breakdown to maintain viscosity and deliver complete gearbox protection.

• Excellent EP protection against micropitting and scuffing wear.
• Superior high-temperature viscosity retention.
• Inhibits rust and corrosion to promote long component life.
• High viscosity index for cold-weather startup protection.
• Resists oxidation to fight sludge carbon and varnish deposits.
• Excellent foam-resistance for reduced gear and bearing wear.
