However, here are some important considerations:
* Temperature: The appropriate viscosity depends on the ambient temperature. In colder temperatures, you might need to use a multi-grade oil such as SAE 15W-40. Consult your owner's manual for specific temperature recommendations.
* Oil Type: The Farmall 656 uses a diesel engine oil. Make sure the oil you choose is designed for diesel engines and meets the manufacturer's specifications.
* API Rating: The oil should meet or exceed the API CF-4 or API CG-4 rating. You can check the oil container for the API certification.
* Additives: It's important to use an oil with the proper additives to protect the engine components, especially in high-stress farm environments.
Always consult your Farmall 656 owner's manual for the most up-to-date and accurate information on engine oil specifications and recommendations.
