# LBKN826141

Natural Gas Engine Oil for Vehicular Applications

Kendall® Super-D NG is a high-quality, dispersant-detergent gas engine oil specially designed for use in vehicular natural gas engines that have slider-follower valve trains. It is formulated with a higher level of antiwear additives than conventional low-ash gas engine oils to meet the enhanced wear protection requirements of diesel engines converted to natural gas service. It is particularly recommended for use in transit buses, school buses, delivery trucks, and other vehicles equipped with Cummins, Detroit Diesel, or John Deere CNG or LNG engines.
