Article-No: 340043 NATURAL GAS ENGINES

Summit GEO SH (Ashless) Series are unique ashless, soft medium TBN gas engine oils manufactured from the finest synthetic base oils  to optimize performance.  Summit GEO SH (Ashless) Series gas engine oils  are recommended for those two-stroke and four-stroke engines that are more sensitive or prone to fouling  from metallic detergent additives that would contribute to combustion chamber deposits, spark plug fouling or ash pounding. They can be used in lean- or rich-burn service,  naturally aspirated or turbo-charged engines.  They are formulated with the latest in gas engine oil additive technology with oxidation & nitration inhibitors and nitrogen-based, non-metallic dispersants to disperse combustion by-products for improved engine cleanliness.
