ExxonMobil Mobil Pegasus 15W-40 40

Mobil Pegasus Special is a high quality SAE 15W-40 gas engine oil primarily intended for the lubrication of crankcases and power cylinders of spark-ignited two- and four-cycle gas-fueled engines. It is ideally suited for engines subjected to a wide range of ambient temperatures during startup and operation. This oil is also recommended for the lubrication of the cylinders and crankcases of reciprocating compressors processing clean natural gas. Pegasus Special is formulated from high quality narrow-cut mineral base oil and a balanced ashless detergent additive system. It is designed to provide excellent protection of engine and compressor components while reducing combustion chamber deposits in all engines and port carboning in two-cycle engines. Pegasus Special exhibits a high level of chemical stability and resistance to oxidation and nitration to help provide long oil life and lower filter replacement costs. Mobil Pegasus Special has excellent anti-corrosion properties, which helps prevent corrosive wear in cylinders, valve areas and bearings resulting in longer engine life. The anti-wear properties helps minimise wear of rings, liners, and bearings.Crankcases and power cylinders of spark-ignited two- and four-cycle gas engines; Engines subjected to remote startup under cold ambient conditions; Mainline applications where engines are shut down for long periods and must start and come on line quickly; Recommended for applications requiring ashless or very low ash formulations; Where port carboning of two-cycles gas engines is a concern; Reciprocating compressor cylinders compressing clean natural gas
