HIGH TBN/LOW PHOSPHORUS ECONOMIC STUO LUBRICANTS

摘要

A high TBN/low phosphorus economic STUO lubricant is provided to be used to improve the capacity of a brake, and to improve the function of protecting against abrasion of a tractor engine. A super tractor oil universal lubricant composition includes lubricant viscosity oil. The lubricant oil is formulated as an additive component containing one or more metal detergent; one or more phosphorus-base abrasion preventing agent; and one or more organo-molybdenum compounds. The ratio between the content(ppm) of metal based on the total weight of the lubricant composition and the total number of bases of the lubricant composition is in a range of about 210 to 450(ppm/mg KOH/g).
