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.

Addition of an aminosulfonate product to an inorganic nitrogen-containing salt provides a composition of matter with improved properties. In particular, 2-acrylamido-2-methylpropanesulfonic acid and its derivatives can be added to ammonium nitrate to provide improved prills.
