Overall, maintenance for the ISL G Near Zero is similar to that of diesel engines, but there are a few key differences:
Motor oil specifically formulated for natural gas engines is required. Do not use diesel engine oil in a natural gas engine. If diesel engine oil is used, valve torching, piston scuffing and reduction in spark-plug life will occur. For more information see the Product Information Bulletin available on cumminswestport.com.
