lubricating ability

This characteristic may aid in the molecule's boundary lubricating ability.

However, jet fuel tends to have poor lubricating ability in comparison to diesel, thereby increasing wear on fuel pumps and other related engine parts.

Most are still trying to figure out how to adapt their designs to use HCFC's, which have less lubricating ability than CFC's, in equipment that customers expect to run for 15 to 20 years without maintenance.
