What happens if I underload a generator?
All engines are designed to operate under varying load, ranging from the maximum down to the minimum. Problems occur when light loading (min load) is sustained for long periods of time resulting in the engine not getting up to its normal temperature. Oil in the cylinder that is normally burnt is heated and a lacquer is formed on the cylinder liner. If the light loading continues, visible blue smoke will appear and the engine will require service work to deglaze the liner or replace it.
