GEAR OIL GP
HIGHLY COMPOUNDED, NON-EP WORM GEAR LUBRICANT
Phillips 66® Gear Oil GP is a premium, non-EP gear lubricant designed for heavily loaded worm gear drives operating at low to medium speeds and moderate to high temperatures. It is particularly recommended for worm gear swing drives in bucket trucks and other mobile equipment.
Formulated with high-viscosity base oils compounded with fatty oil and specialized anti-wear additives, Gear Oil GP delivers high film strength and load-carrying capacity. Its excellent oiliness reduces friction, ensuring effective lubrication for bronze-on-steel and other nonferrous alloy worm gear drives. This helps lower gearbox operating temperatures and improves overall efficiency.
Gear Oil GP emulsifies with water to maintain reliable lubricity, offering protection for worm gear drives in wet or humid environments.
