* SAE 5W-40: This is a full synthetic oil that is suitable for most Dodge diesel engines. It provides good protection against wear and tear, and it can also help to improve fuel economy.
* SAE 15W-40: This is a conventional oil that is suitable for older Dodge diesel engines. It is not as lightweight as synthetic oils, but it can still provide good protection against wear and tear.
* SAE 0W-40: This is a synthetic oil that is specifically designed for cold weather climates. It flows more easily in low temperatures, which can help to reduce wear and tear on your engine.
In addition to the SAE viscosity grade, you should also consider the API service rating of the oil. The API service rating indicates the level of protection that the oil provides against wear, tear, and deposits. The higher the service rating, the better the protection. For Dodge diesel engines, you should choose an oil with an API service rating of at least CI-4.
You should also consult your vehicle owner's manual for specific recommendations on engine oil.
Ultimately, the best way to choose the right engine oil for your Dodge diesel is to talk to a qualified automotive technician. They can help you assess your specific needs and recommend the best oil for your vehicle.
