What kind of oil does a Dodge diesel take?
When it comes to maintaining your Dodge diesel truck, choosing the right oil is crucial for ensuring optimal performance and longevity. Whether you own a Ram 2500, 3500, or another Dodge diesel model, understanding the specific oil requirements can help you keep your engine running smoothly and efficiently.
Understanding the Importance of the Right Oil
Diesel engines operate under higher compression and generate more heat compared to gasoline engines. As a result, they require oil that can withstand extreme conditions while providing adequate lubrication and protection. Using the wrong oil can lead to increased wear, reduced efficiency, and even engine damage over time.
Recommended Oil for Dodge Diesel Engines
Dodge diesel trucks, particularly those equipped with Cummins engines, typically require heavy-duty engine oil that meets specific standards. Here’s what you need to know:
- Viscosity Grade: Most Dodge diesel engines recommend 15W-40 oil for normal operating conditions. However, in colder climates, 5W-40 synthetic oil is often preferred for better cold-start performance.
- API Certification: Look for oil that meets the API CK-4 or CJ-4 specifications. These certifications ensure the oil is designed for modern diesel engines and provides protection against wear, deposits, and oil breakdown.
- Synthetic vs. Conventional: While conventional oil is acceptable, synthetic oil is often recommended for Dodge diesel engines due to its superior performance in extreme temperatures and extended drain intervals.
Always refer to your vehicle’s owner’s manual for the manufacturer’s specific recommendations, as oil requirements may vary depending on the model year and engine type.
Steps to Choose the Right Oil
Follow these steps to ensure you’re using the correct oil for your Dodge diesel:
- Check your owner’s manual for the recommended oil viscosity and specifications.
- Consider your driving conditions, such as climate and towing needs, to determine if synthetic oil is a better choice.
- Purchase oil from a reputable brand that meets the required API certification.
- Consult with a trusted mechanic or auto service provider if you’re unsure about the best oil for your vehicle.
By following these steps, you can ensure your Dodge diesel engine receives the proper care and lubrication it needs to perform at its best.

Frequently Asked Questions
Will 15w40 hurt a 6.7 Cummins?
Do not run 15w40 in 6.7s.... the main bearing tolerances are too tight and it causes the crank gear to spin. Run 5w40 only.
Is 15W-40 OK for diesel engines?
Both 15W-40 and 10W-30 oils are multi-grade oils commonly used in diesel engines. The numbers in their names refer to their viscosity at different temperatures. The “W” stands for winter, indicating the oil's performance in cold weather, while the numbers reflect its viscosity at high temperatures.
What oil is recommended for Cummins diesel?
Valvoline's Premium Blue Engine Oil is endorsed by Cummins and has been tested extensively by Cummins in stationary and EGR on-road engines, including engines powered by diesel, CNG, LNG, as well as engines equipped with DPFs. It is tested and approved against industry standard specifications such as SAE, TMC and CES.
Which 6.7 Cummins to avoid?
We recommend staying away from the 1991, 1992, 1993, 1999, 2001, 2003, 2006, 2007, 2008, and 2011 models. Many issues stem from these years. A few of the common appear in the format of transmission failure, charging system troubles, and electrical issues. These can be costly to handle and inconvenient for any driver.
Why did Cummins switch to 10W30?
The most common reason for the change is the increase in fuel economy by switching to lower viscosity oil. Fuel economy improvements are correlated with viscosity.
What's the difference between 5w40 and 15w40?
5w40 and 15w40 is that both oil have same viscosity at high temperature say 100 degree celsius but both oil will have different viscosity at low temperature say 0 degree celsius . 5w will be less viscous than 15w . meaning 5w will flow more easily than 15w at low temperature.
What type of oil for Dodge Ram 2500 diesel?
Low ash diesel engine oil is required.
Is EcoDiesel the same as diesel?
EcoDiesel is a unique powertrain system that maximizes horsepower and torque while optimizing every drop of fuel from your tank. While diesel systems of the past were known for their gas-guzzling qualities, EcoDiesel is a greener technology that makes the most out of both power and efficiency.
What oil does a Dodge EcoDiesel take?
5W-40 synthetic blend
The 3.0L EcoDiesel V6 engine requires a 5W-40 synthetic blend motor oil. This version of the RAM 1500 also requires DEF fluid. Based on manufacturer recommendations, you'll achieve the best results using MOPAR DEF fluid.
How much oil does a 3.0 L V6 EcoDiesel take?
The 3.0L Eco-diesel engine requires synthetic oil and more of it. In Ram applications, it takes 10.5 quarts. In Jeep applications, it takes 8 quarts. So, oil changes will cost a bit more than on conventional engines.
