A lubricant comprising (a) an oil of lubricating viscosity; (b) a polyether of number average molecular weight 1000 to 10,000; said polyether comprising alkylene oxide monomer units, where the alkylene group contains 3 to 6 carbon atoms, and ethylene oxide monomer units; and (c) one or more anti-foam agents, where the lubricant has a sulfated ash content of less than about 0.7 percent, is useful for lubricating a stationary gas engine where the engine drives a compressor and where both the engine and the compressor are lubricated with the same lubricant.

Provided herein are aqueous mobility enhancing compositions for improving travel of metal containers through a manufacturing process, including manufacturing equipment and conveyors; methods for making such compositions, and methods for reducing a coefficient of friction on a surface of a metal container by contacting the container with a disclosed composition and containers having a metal surface having a composition of the invention dried-in-place thereon. The compositions are useful for producing desirable slip angle characteristics on surfaces of metal containers that have been subjected only to cleaning processes, or that have been both cleaned and conversion coated.
