Summit GEO PS-140 is a low ash, balanced medium TBN gas engine oil manufactured from a blend of synthetic and mineral base stocks to optimize performance at a lower operating cost versus the full synthetic formulations like Summit GEO SH (Low Ash) Series or GEO SH-140 CA. Summit GEO PS-140 isrecommended for lean or rich-burn service in two-stroke and four-stroke gas engines, naturally aspirated or  turbo-charged.  Summit GEO PS-140 is formulated with the latest in gas engine oil additive technology comprised of superior anti-wear and ant-scuff agents, oxidation & nitration inhibitors and detergent–dispersants to neutralize corrosive gas components, provide excellent protection against valve component recession or beat-in, and disperse combustion by-products for improved gas engine cleanliness and low combustion chamber deposits.
