What is the maximum allowable refill of oil without dry motoring the engine?

The maximum allowable refill of oil without dry motoring the engine is two US quarts. This limitation is in place to prevent the presence of excess oil in the engine, which can result in foaming and decreased lubrication efficiency. When topping off the oil, adhering strictly to this limit helps maintain optimal operating conditions and ensures that the oil system remains effective without causing potential damage or operational issues.

In the context of operations, exceeding the two-quart limit may necessitate dry motoring the engine to eliminate potential oil pooling in the turbine, which could lead to complications during startup or operation. Therefore, understanding and adhering to this limitation is critical for safe and efficient engine management.
