2025 Ram 5500 Engine Oils

High performance heavy-duty diesel engine oil.

Product Features:

• Advanced full synthetic diesel engine oil that helps to extend engine life and fuel economy potential of modern diesel engines operating in severe conditions
• Formulated to help high-performance diesel engines with turbocharger, direct-injection, low-emission designs, and low-sulfur and biodiesel fuel formulations
• Provides excellent oxidation performance, anti-wear, and anti-scuff properties that helps to reduce engine deposits and keep engines running reliably
• Excellent low-temperature performance for increased oil flow to critical bearing surfaces at startup and controlling low-temperature sludge formation
• Provides outstanding protection against oil thickening and degradation, helping to reduce the number of oil changes and oil disposal needs
• Manufacturer Part Number: 122271

Mobil Delvac Extreme 10W-30 is a high-performance synthetic diesel engine oil that helps to deliver extended performance for up to two times beyond OEM recommended oil drain intervals(1) for modern diesel engines operating in extreme conditions. Mobil Delvac Extreme 10W-30 has the potential to improve fuel economy(2) and is recommended for use in a wide range of heavy-duty applications and operating environments found on- and off-highway conditions, including engines operating under heavy loads. Fully backward compatible, it delivers excellent performance in both newer and older heavy-duty engines, meeting or exceeding the requirements of API CK-4, CJ-4, CI-4 PLUS, CI-4, and other service categories. This diesel engine oil provides exceptional high temperature performance, oxidation stability(3), and resistance to corrosive and abrasive wear to help promote long life of critical wear surfaces. Mobil Delvac Extreme 10W-30 also offers excellent low-temperature performance for increased oil flow to critical bearing surfaces at startup, controlling fluidity and pumpability for smooth starting in cold weather. (1-Results may vary based on vehicle/engine condition, driving and environmental conditions Consult OEM or ExxonMobil before implementing extended ODIs. 2-Compared to an SAE 15W-40 conventional diesel engine oil. Savings are dependent on vehicle engine type, outside temperature, driving conditions, and your current engine oil viscosity. 3-Based on the performance in the Volvo T-13 engine test.)
