For the GEN 3, 3.0L EcoDiesel engine, the recommended oil is a 5W-40 weight full synthetic engine oil that adheres to specific FCA material standards and API engine oil categories to ensure optimal performance and protection.
Recommended Engine Oil for GEN 3, 3.0L EcoDiesel
Choosing the correct engine oil is paramount for the longevity and efficient operation of your EcoDiesel engine, particularly the GEN 3, 3.0L variant. Modern diesel engines, with their advanced emissions systems like Diesel Particulate Filters (DPF), require specific oil formulations to prevent damage and maintain compliance.
Oil Specifications
To meet the precise requirements of the GEN 3, 3.0L EcoDiesel engine, the oil must possess the following characteristics:
- Weight (Viscosity): 5W-40
- Type: Full Synthetic
- Required Standards:
- FCA Material Standard MS-12991
- API SN or SN+ engine oil category
Approved Oil Brands and Part Numbers
Several oils are specifically formulated and approved to meet these stringent requirements. When selecting oil, look for products that explicitly state compliance with the aforementioned standards. Examples include:
- Mopar part number 05166241PA
- Mopar part number 05166241GA
- Pennzoil Platinum Euro
Here's a quick summary of the key oil specifications:
Specification | Detail |
---|---|
Weight | 5W-40 |
Type | Full Synthetic |
Standards | FCA Material Standard MS-12991 |
API SN or SN+ |
Understanding EcoDiesel Oil Requirements
The specific oil recommendations for your EcoDiesel are not arbitrary; they are critical for the engine's unique design and the sophisticated emissions control systems it employs.
Why 5W-40 Full Synthetic?
- 5W-40 Viscosity: This multi-grade viscosity ensures proper lubrication across a wide range of temperatures. The "5W" indicates good flow in cold weather for easier starts and reduced wear, while the "40" signifies appropriate thickness at high operating temperatures to protect engine components.
- Full Synthetic: Full synthetic oils offer superior performance and protection compared to conventional or synthetic blend oils. They are engineered to provide better thermal stability, resistance to oxidation, and improved film strength, which are vital for the high demands of diesel engines.
Importance of Standards (MS-12991 & API SN/SN+)
- FCA Material Standard MS-12991: This is a proprietary standard set by Fiat Chrysler Automobiles (FCA) specifically for their engines, including the EcoDiesel. It ensures the oil has the correct chemical composition and performance characteristics to protect internal engine components, maintain optimal fuel efficiency, and importantly, be compatible with emission control systems like the Diesel Particulate Filter (DPF). Oils not meeting this standard can lead to DPF clogging or damage.
- API SN or SN+: These are service categories defined by the American Petroleum Institute (API) that denote the oil's performance in gasoline engines. While the EcoDiesel is a diesel engine, the inclusion of API SN or SN+ signifies the oil's high level of protection against engine wear, sludge formation, and piston deposits, which can also benefit modern diesel designs.
Where to Find More Information
Always refer to your vehicle's owner's manual for the most accurate and up-to-date information regarding maintenance schedules and fluid specifications. Additional technical service bulletins (TSBs) from the manufacturer can also provide specific guidance.
