2019 Ram 1500 oil capacity and type are critical details for any owner looking to maintain their truck’s legendary performance and durability. Knowing these specifications ensures your engine receives the precise lubrication it needs to operate efficiently, prevent wear, and extend its lifespan. The 2019 Ram 1500, a popular choice for its robust capabilities and refined ride, offered a range of powerful engine options, each with its unique oil requirements. Adhering to the manufacturer’s recommendations is paramount, not just for performance but also to maintain warranty coverage and avoid costly repairs down the line.
Understanding Your 2019 Ram 1500 Engine Options
The 2019 model year introduced the fifth generation (DT) Ram 1500, alongside the continued production of the fourth generation (DS) “Classic” model. This means there were several engine choices across these platforms, influencing oil specifications. The most common gasoline engines were:
3.6L Pentastar V6: A reliable and efficient powerplant, often featuring eTorque mild-hybrid technology in the new DT generation.
5.7L HEMI V8: The iconic HEMI, available with or without eTorque, known for its formidable power and torque.
Additionally, while less common for the 2019 model year launch of the DT body style, the 3.0L EcoDiesel V6 was also offered in the DS Classic model and eventually made its way into the DT lineup later. Each of these engines demands specific oil types and capacities tailored to their design and operating characteristics.
Detailed 2019 Ram 1500 Oil Capacity and Type by Engine
Let’s break down the precise oil specifications for each engine to ensure you’re using the correct products for your truck.
3.6L Pentastar V6 Engine (with or without eTorque)
For the 3.6L Pentastar V6, found in both the DS Classic and the new DT body style, maintaining proper oil viscosity and quality is essential for the variable valve timing system and overall engine health.
Oil Capacity: Approximately 6.0 US Quarts (5.7 Liters)
Recommended Oil Type: SAE 5W-20 Full Synthetic
API Service Classification: Must meet API SN, SM, SL, or SJ standards, or the latest API SP specification, along with ILSAC GF-5 or GF-6 for enhanced fuel economy and engine protection.
The use of full synthetic oil is often recommended for modern engines like the Pentastar V6, especially when equipped with eTorque, due to its superior protection over a wider temperature range and longer service intervals.
5.7L HEMI V8 Engine (with or without eTorque)
The mighty 5.7L HEMI V8 is renowned for its robust performance and features Chrysler’s Multi-Displacement System (MDS), which requires specific oil to function correctly and protect the engine.
Oil Capacity: Approximately 7.0 US Quarts (6.6 Liters)
Recommended Oil Type: SAE 5W-20 Full Synthetic
API Service Classification: Must meet API SN, SM, SL, or SJ standards, or the latest API SP specification, along with ILSAC GF-5 or GF-6.
Just like the Pentastar, a full synthetic 5W-20 is crucial for the HEMI, particularly to support the MDS system, which deactivates cylinders under light load to save fuel. The correct oil ensures proper hydraulic pressure and lubrication for these sophisticated components.
3.0L EcoDiesel V6 Engine (DS Classic and DT)
For those with the EcoDiesel, the oil requirements are distinctly different due to the nature of diesel combustion and emissions systems.
Oil Capacity: Approximately 10.5 US Quarts (9.9 Liters)
Recommended Oil Type: SAE 5W-40 Synthetic Diesel Oil
* API Service Classification: Must meet API CJ-4 or CK-4 standards. It is also crucial that the oil is Low Ash (ACEA C3 or specific Chrysler material standard MS-11106) to protect the Diesel Particulate Filter (DPF).
Using the wrong oil in an EcoDiesel can severely damage the DPF and other emissions control components, leading to very expensive repairs. Always verify the specific MS standard in your owner’s manual.
The Importance of Correct Oil for Your Ram 1500
Choosing the precise oil capacity and type isn’t just a suggestion; it’s vital for several reasons:
1. Optimal Lubrication: The correct viscosity ensures that oil flows properly at different temperatures, creating a protective film between moving parts to reduce friction and wear.
2. Heat Dissipation: Engine oil plays a significant role in cooling engine components, especially in high-performance engines like the HEMI or the hard-working EcoDiesel.
3. Engine Cleanliness: Modern oils contain detergents and dispersants that clean deposits and suspend contaminants, preventing sludge buildup and keeping the engine internals spotless.
4. Fuel Efficiency: The right oil can reduce internal engine friction, contributing to better fuel economy. Using the wrong viscosity can lead to increased drag and reduced efficiency.
5. Emissions Control: Especially for diesel engines with DPFs, specific low-ash oils are designed to prevent clogging and maintain the effectiveness of exhaust aftertreatment systems.
6. Warranty Compliance: Using oil that doesn’t meet the manufacturer’s specifications can void your truck’s powertrain warranty.
Choosing the Right Oil and Filters
Always refer to your 2019 Ram 1500’s owner’s manual for the most accurate and up-to-date specifications. The manual will confirm the specific API service category, viscosity grade, and any additional certifications (like Chrysler’s own MS standards).
When selecting engine oil, prioritize full synthetic options as they offer superior protection and performance for modern engines. They are engineered to withstand higher temperatures, resist breakdown, and provide better cold-start protection than conventional or synthetic blend oils.
Equally important is the oil filter. Always use a high-quality oil filter, ideally a genuine Mopar part or an equivalent aftermarket filter that meets OEM specifications. A good filter removes contaminants effectively without restricting oil flow.
Oil Change Intervals and Best Practices
For most 2019 Ram 1500 models under normal driving conditions, the recommended oil change interval is typically between 7,500 to 10,000 miles (12,000 to 16,000 km) or every 6-12 months, whichever comes first. However, if you frequently tow heavy loads, drive in extreme temperatures, operate in dusty environments, or make many short trips, your truck is operating under “severe duty” conditions. In these cases, more frequent oil changes, possibly every 5,000 miles (8,000 km) or 6 months, may be advisable.
Regularly check your oil level between changes and top off if necessary. This simple habit can prevent potential engine damage from low oil levels.
In conclusion, understanding the 2019 Ram 1500 oil capacity and type for your specific engine is a fundamental aspect of responsible truck ownership. By using the correct type and amount of oil, along with quality filters and adhering to recommended service intervals, you’ll ensure your Ram 1500 continues to deliver reliable performance for many years and miles to come. When in doubt, always consult your owner’s manual or a certified Ram service technician.
