KIT-SEAL- 2350969 - Caterpillar

Commercial oil specifications do not exist for Cat engines that operate on gaseous fuels. The performance of lubrication oil for gas engines is determined by a field evaluation. Successful field operation has been achieved with oils that meet the following guidelines:
Caterpillar recommends the use of oils that are formulated specifically for heavy-duty gas engines. Do not use oils that are specially formulated for gasoline engines or for diesel engines.
Caterpillar does not recommend multigrade oils for use in gas engines.
Caterpillar recommends the use of oils that have a sulfated ash content between 0.40 and 0.60 percent.
The oil must demonstrate adequate protection for a minimum of 7000 hours in a field evaluation under controlled conditions.7000 Hour Field Performance Evaluation
Caterpillar recommends oils for gas engines that meet the requirements of the 7000 hour field evaluation. The 7000 hours of field service must be documented. Standard and/or Low Emission engine configurations may be used for the evaluation. The field evaluation must be performed in an engine configuration that is similar to the engine that will use the oil that is proposed. The field evaluation must be performed at a power level that is at least equal to the power that is required by the engine that will use the oil that is proposed.Field evaluations may identify commercial brands of oil with successful results. Caterpillar will not endorse a commercial brand of oil because of the results. The oil company can use the results of the field evaluation as a proof of the oil performance. The oil company is responsible for the performance and the quality of the oil, and for any changes in the formulation of the oil. Before purchasing a lubrication oil for a gas engine, discuss the claims of performance for the oil with the oil supplier.For additional details on the 7000 hour Field Performance Evaluation, refer to this Special Publication, "Field Evaluation of Commercial Oil" topic.
