Specifications

Generally, the higher TBN value more the alkalinity reserve or acid neutralizing capacity
the oil contains.
Your generator requires 15W40 diesel lube oil only. For the first 25 hours a non
synthetic lube oil is required. After the initial 25 hour break in process, synthetic diesel
engine lube oil 5w40 to 15w40 is required.
The engine is designed in such a way that it is difficult to overfill it and as you can see in
this illustration above oil should be filled until it reaches just below the oil filter neck.
