Valvoline Premium Blue GEO LA – ES
Valvoline™ Premium Blue™ GEO LA - ES is a superior low ash SAE 40 engine oil recommended for use in stationary high output, highly turbocharged, spark ignited natural gas engines. It is formulated with premium quality paraffinic base oils and additive components to provide outstanding extended drain capability in gaseous fueled engines. The ash content of the oil is optimized to reduce spark plug fouling and forming of combustion chamber “hot-spots” that can lead to increased valve guttering, pre-ignition and knock.
Valvoline Premium Blue GEO LA-ES is approved by Cummins1 for use in QSV81G, QSV91G, and QSK60G Series engines. It is formulated to meet the requirements of Cummins roller-follower natural gas engines in stationary service. It is also approved for use in Waukesha Cogeneration engines. For other engines, please refer to engine manufacturer’s specifications and oil testing requirements.
