Specialty Oils


Gear Oil GP

Phillips 66® Marok® is a high-quality, adhesive, extreme-pressure (EP) lubricant specially developed to lubricate in the presence of moisture or where oil leakage is a problem. It is recommended for the lubrication of marine, mining, and industrial equipment operating in wet environments, and for the lubrication of air-powered tools, such as rock drills and jackhammers.


• Good extreme-pressure properties

• Protects against wear and seizure

• Excellent adhesion to metal surfaces in the presence of moisture

• Resists dripping and leakage

• Protects against rust and corrosion

• Low odor


• Pneumatic percussion tools such as jackhammers, pavement breakers, and rock drills

• Mining equipment such as demolition hammers, chipping hammers, and drifters

• Marine applications such as stern tube bearings, oil-lubricated tunnel bearings, and cylinder lubricant for steam engines and crosshead engines

• Drive chains and overhead conveyors where a non-drip lubricant is required

• Enclosed industrial gear drives where oil leakage is a problem
