The 2019 Ram 1500 3.6 oil capacity and type are critical pieces of information for any owner looking to properly maintain their truck and ensure its longevity. The 2019 Ram 1500, particularly with the 3.6L Pentastar V6 engine, is a popular choice for its balance of power, efficiency, and capability. Understanding the specific lubrication requirements for this engine is not just about keeping the truck running; it’s about optimizing performance, protecting internal components, and maintaining your warranty.
Neglecting these specifications can lead to premature engine wear, reduced fuel economy, and potentially costly repairs down the line. This article will delve into the precise oil capacity and the recommended oil type, along with best practices for oil changes, helping you keep your 2019 Ram 1500 running smoothly for years to come.
Understanding the 2019 Ram 1500 3.6L Pentastar V6 Oil Capacity
For the 2019 Ram 1500 equipped with the 3.6L Pentastar V6 engine, the recommended engine oil capacity is 6.0 quarts (approximately 5.7 liters). This measurement includes the oil required to fill a new oil filter. It’s crucial to always use this specified amount to ensure proper lubrication without overfilling or underfilling the crankcase.
While 6.0 quarts is the standard, it’s always best practice to perform a final check with your truck’s dipstick after adding the new oil and running the engine briefly. Park the truck on a level surface, wait a few minutes for the oil to settle, then pull the dipstick, wipe it clean, reinsert it completely, and pull it out again to read the level. The oil level should be within the acceptable range marked on the dipstick, typically between the “MIN” and “MAX” lines or specific hash marks. An accurate dipstick reading is the ultimate confirmation that your engine has the correct amount of oil.
Choosing the Right Oil Type for Your 2019 Ram 1500 3.6
Selecting the correct oil type for your 2019 Ram 1500’s 3.6L Pentastar V6 engine is equally as important as the capacity. Ram (and its parent company, Stellantis) has very specific recommendations to ensure optimal engine performance, fuel efficiency, and protection.
The primary recommendation for the 3.6L Pentastar V6 in the 2019 Ram 1500 is SAE 0W-20 Full Synthetic engine oil.
Let’s break down what this means:
SAE 0W-20: This is the oil’s viscosity grade.
The “0W” indicates how the oil performs in cold temperatures (“W” stands for winter). A lower number means the oil is thinner and flows more easily when cold, providing quicker lubrication during startup—which is when most engine wear occurs. This is particularly beneficial in colder climates across the US and Canada.
The “20” indicates the oil’s viscosity at operating temperature. It’s a relatively thin oil, which helps reduce internal engine friction, contributing to better fuel economy.
Full Synthetic: This is a crucial distinction. Synthetic oils are engineered in laboratories to provide superior lubrication, thermal stability, and resistance to breakdown compared to conventional or even synthetic blend oils. For modern engines like the Pentastar V6, which often operate at higher temperatures and with tighter tolerances, full synthetic oil is either highly recommended or required. It offers better protection against wear, sludge buildup, and low-speed pre-ignition (LSPI), a phenomenon that can cause significant engine damage.
Beyond viscosity and base stock, look for specific certifications and specifications on the oil bottle:
API Certification: Ensure the oil meets the latest American Petroleum Institute (API) service classification, such as API SN, SN PLUS, or SP. These classifications indicate that the oil has met certain performance standards related to engine protection, emissions system compatibility, and fuel economy.
ILSAC GF-5 or GF-6: The International Lubricant Standardization and Approval Committee (ILSAC) GF-5 or GF-6 specifications further confirm the oil’s quality, particularly regarding fuel economy and protection for modern engines.
Chrysler MS-6395: This is arguably the most critical specification for your Ram. Mopar (Chrysler’s parts division) has its own engineering specification, MS-6395, which indicates that the oil has been tested and approved to meet the exact requirements for your engine. Using an oil that meets or exceeds MS-6395 is often a requirement to maintain your vehicle’s powertrain warranty.
Why the Right Oil Matters for Your Pentastar V6
The 3.6L Pentastar V6 engine is a sophisticated, high-performance power plant. Using the correct oil type and capacity is vital for several reasons:
1. Engine Longevity and Protection: The precisely formulated 0W-20 full synthetic oil provides optimal lubrication to all moving parts, minimizing friction and wear, especially critical during cold starts and high-temperature operation.
2. Fuel Efficiency: The lower viscosity of 0W-20 oil reduces drag within the engine, allowing it to operate more efficiently and thus improving fuel economy.
3. Performance Stability: Correct oil helps maintain consistent engine temperatures and pressure, ensuring the engine performs as designed under various conditions.
4. Emission Control: Proper lubrication helps reduce deposits and ensures that emission control systems, like catalytic converters, operate effectively.
5. Warranty Compliance: As mentioned, using oil that meets the Ram/Mopar specifications (especially MS-6395) is often a non-negotiable requirement for your engine’s warranty to remain valid.
6. Addressing LSPI: Modern direct-injection, turbocharged engines (even naturally aspirated ones like the Pentastar can be susceptible) face a risk of Low-Speed Pre-Ignition (LSPI). Oils formulated to the latest API and ILSAC standards, especially SN PLUS or SP, are designed to combat LSPI, protecting against potentially severe engine damage.
Oil Change Best Practices for Your Ram 1500
Follow the Oil Life Monitor: Your 2019 Ram 1500 is equipped with an Oil Life Monitoring (OLM) system. This system calculates oil degradation based on driving conditions (temperature, RPM, idle time, etc.) and will alert you when an oil change is due. While it can often extend intervals beyond traditional mileage numbers, it’s a reliable indicator. Do not exceed 10,000 miles (16,000 km) or 12 months, whichever comes first, even if the OLM hasn’t triggered.
Always Change the Filter: The oil filter works hand-in-hand with the oil. Always replace the oil filter with a new, high-quality filter (preferably Mopar or an equivalent specified for your Ram 1500) every time you change the oil. A clogged or inefficient filter can compromise even the best new oil.
DIY Tips (If Applicable): If you’re performing the oil change yourself, ensure you have the correct tools, safety equipment (jack stands, wheel chocks), and a proper container for used oil. Always refer to your owner’s manual for step-by-step instructions and torque specifications for the drain plug.
* Dispose of Used Oil Properly: Never pour used engine oil down the drain or into the ground. Most auto parts stores and service centers offer free recycling for used motor oil.
Conclusion
Maintaining your 2019 Ram 1500 with the 3.6L Pentastar V6 engine properly means paying close attention to the details of its lubrication requirements. Knowing that its oil capacity is 6.0 quarts (5.7 liters) and that it requires SAE 0W-20 Full Synthetic oil that meets API SN/SN PLUS/SP, ILSAC GF-5/GF-6, and especially Chrysler MS-6395 specifications is paramount. By adhering to these guidelines and following recommended service intervals, you’ll ensure your Ram 1500 delivers reliable performance, optimal fuel efficiency, and a long, healthy life on the road. When in doubt, always consult your owner’s manual – it’s the definitive guide to your truck’s maintenance needs.
