* Year and Model: The best oil depends on the exact year and model of your Ram. Older engines might have different needs than newer ones.
* Driving Conditions: Do you drive in extreme temperatures, tow heavy loads, or frequently drive in stop-and-go traffic? These factors influence oil viscosity and additives.
* Owner's Manual: Your owner's manual is the most reliable source of information. It will specify the recommended oil type, viscosity, and API service category.
General Recommendations:
* Viscosity: Consult your owner's manual for the recommended viscosity (e.g., 5W-30, 10W-30).
* API Service Category: Look for an oil that meets or exceeds the API service category specified in your owner's manual (e.g., SN, SL).
* Synthetic vs. Conventional: Synthetic oil generally offers better performance and protection, especially in extreme conditions. However, it can be more expensive. Conventional oil is a more budget-friendly option.
* Brand: Many reputable brands offer high-quality motor oil. Some popular options include:
* Valvoline
* Mobil 1
* Pennzoil
* Castrol
* Quaker State
Important Note: Always follow the recommendations in your Dodge Ram's owner's manual. Using the wrong type of oil can damage your engine.
