Summary:

Abandonment of the concept that gas engines can be operated economically using straight mineral oils and clay filters and the switch to detergent oils designed for specific use in natural gas engines has been handicapped by attempts to use conventional automotive or diesel metallo-organic detergent oils, and by the attempts to develop ashless oils without investigating all of the parameters and pitfalls associated with the use of ashless dispersants.At present, the weaknesses of ashless oils can be overcome only through the use of a balanced combination of the proper base stock and certain metallo-organic detergents. Careful analysis of engine operations over relatively long periods of time will demonstrate to the operator that ash from a properly designed natural gas engine oil does not adversely affect engine operations.It has been our experience that laboratory engine tests are of relatively little use in the evaluation of natural gas engine oils. The real proof of performance is only through extensive field testing in a variety of engines and under a variety of operating conditions. This paper concerns itself with field test work which has shown some of the problems associated with the use of both ashless and improperly designed ash-containing oils in the relatively low and intermediate speed (up to 1250 rpm) engines. These data show conclusively that properly designed detergent (high ash) oils give outstanding performance
