A lubricant (colloquially, lube) is a substance (usually a liquid) introduced between two moving surfaces to reduce the friction and wear between them. Worldwide, more than 50 million tonnes of lubricants are consumed annually. Automotive engine lubricants comprise approximately 50% and hydraulic fluids with transmission oils 30% of lubricants volume-wise. In developed nations, lubricants contribute to nearly 1/4 of total pollution released to environment.
