Abstract : The performance of a candidate high-temperature lubricant was determined under cyclic operating conditions of idle, maximum torque, and maximum power at intermediate and high oil temperatures. The results were compared with previous oil performance results obtained during steady-state, high-temperature operation. Operation at the cyclic conditions resulted in approximately twice the piston top groove fill deposits. This result confirmed the need to include cyclic operation requirements in any future high-temperature lubricant specification. (MM)
