Onan no longer makes engines. But with the older ones it is hard to say. Both had very good engines. Some better than others. I would say Kohler had the better single cylinder engine after Onan stopped making the LK. Onan had better RV generator engines. On the larger units they were both the same in quality and support.
The amount of oil needed for an Onan generator typically depends on the specific model and engine size. Most Onan generators require between 1 to 2 quarts of oil. It's essential to consult the owner's manual for your specific model to determine the exact oil capacity and type recommended for optimal performance. Regular oil checks and changes are crucial for maintaining the generator's efficiency and longevity.
