2020 Ram 3500 oil capacity and type are critical specifications for maintaining the longevity and optimal performance of this robust heavy-duty truck. Whether you rely on your Ram 3500 for heavy hauling, towing, or as a dependable workhorse, understanding its specific lubrication needs is paramount for ensuring its powerful engines operate efficiently and reliably for years to come. Using the correct oil type and adhering to the recommended capacity not only protects the intricate internal components but also helps maintain fuel efficiency and can prevent costly repairs down the road.
The 2020 Ram 3500 is offered with a choice of potent engines, each with its unique oil requirements. These include the gasoline-powered 6.4L HEMI V8 and the renowned 6.7L Cummins Turbo Diesel, which comes in both standard output and high output variants. Given the distinct design and operational characteristics of gasoline and diesel engines, their lubrication needs differ significantly, making it essential for owners to consult their owner’s manual or a reliable resource for precise information.
Essential Details: 2020 Ram 3500 Oil Capacity and Type
To properly maintain your truck, let’s break down the oil specifications for each engine option available in the 2020 Ram 3500.
For the 6.4L HEMI V8 Gasoline Engine:
The 6.4L HEMI V8 engine is a powerhouse, delivering impressive horsepower and torque for demanding tasks. Its lubrication needs are tailored to gasoline engine operation, focusing on wear protection, thermal stability, and deposit control.
Oil Capacity: The 6.4L HEMI V8 engine typically requires 7 quarts (6.6 liters) of engine oil with a filter change. It’s always a good practice to start by adding slightly less than the full capacity, then check the dipstick and top up as needed to ensure you don’t overfill.
Oil Type: For optimal performance and protection, Ram recommends using SAE 0W-20 full synthetic engine oil. The oil must meet Chrysler Material Standard MS-6395. Always look for oils that carry the API Starburst symbol, indicating it meets the latest industry standards for gasoline engines. The 0W-20 viscosity is chosen for its excellent cold-start performance, ensuring quick lubrication even in chilly temperatures, and its ability to maintain adequate film strength at operating temperatures.
For the 6.7L Cummins Turbo Diesel Engine (Standard Output & High Output):
The legendary 6.7L Cummins Turbo Diesel engine is the heart of the Ram 3500’s heavy-duty capability. Diesel engines operate under much higher compression ratios and generate more soot and heat than gasoline engines, thus requiring specially formulated diesel engine oils. Both the standard and high output versions typically share the same oil specifications due to their core engine design.
Oil Capacity: The 6.7L Cummins Turbo Diesel engine has a significantly larger oil capacity, typically requiring 12 quarts (11.3 liters) of engine oil with a filter change. This larger capacity helps with heat dissipation and extends the oil change intervals by providing more volume to dilute contaminants.
Oil Type: For the 6.7L Cummins, Ram specifies the use of SAE 15W-40 or 5W-40 full synthetic diesel engine oil. Critically, the oil must meet the API CK-4 (or CJ-4) service category. CK-4 oils are engineered to provide enhanced protection against oxidation, shear stability, aeration, and contamination compared to older categories, which is vital for modern diesel engines equipped with emissions control systems like Diesel Particulate Filters (DPFs).
SAE 15W-40 is a common choice for its robust protection in a wide range of operating temperatures.
SAE 5W-40 full synthetic offers superior cold-weather starting and flow characteristics, making it an excellent option for colder climates while still providing robust protection at operating temperatures.
Choosing a full synthetic diesel oil can offer benefits like improved thermal stability, extended drain intervals (if permitted by the manufacturer and oil analysis), and reduced wear.
Why Using the Right Oil Matters
Using the correct oil capacity and type is not merely a suggestion; it’s a fundamental requirement for the health of your 2020 Ram 3500’s engine. Here’s why it’s so crucial:
Engine Protection: The right oil provides a protective film between moving parts, preventing metal-on-metal contact and reducing wear. Incorrect oil can lead to premature wear of bearings, camshafts, and other critical components.
Temperature Regulation: Engine oil helps dissipate heat generated by friction and combustion. The correct viscosity ensures it flows properly to carry heat away from critical areas.
Deposit Control: Modern engine oils contain detergents and dispersants that prevent the formation of sludge and varnish, keeping the engine clean and free from blockages that can restrict oil flow.
Fuel Efficiency: An oil with the correct viscosity and friction modifiers reduces internal engine drag, contributing to optimal fuel economy.
Emissions System Compatibility: Especially for diesel engines, specific oils (like API CK-4) are formulated to be low-ash, protecting sensitive emissions components such as Diesel Particulate Filters (DPFs) from clogging.
Warranty Compliance: Using non-specified oil can void your powertrain warranty, making you liable for potentially expensive repairs.
Checking Your Oil and Recommended Intervals
Regularly checking your oil level is a simple yet vital maintenance task. For both gasoline and diesel engines, aim to check the oil at least once a month, or before long trips. Ensure the truck is on level ground and the engine has been off for several minutes to allow oil to drain back into the pan.
Oil change intervals vary based on your engine, driving conditions, and the type of oil used. Always refer to your 2020 Ram 3500’s owner’s manual for the most accurate and up-to-date recommendations. Generally:
6.4L HEMI V8: Typical intervals can range from 8,000 to 10,000 miles or 6-12 months, depending on usage (e.g., heavy towing, frequent short trips may require shorter intervals).
6.7L Cummins Turbo Diesel: Intervals are often longer, potentially ranging from 10,000 to 15,000 miles or 12 months for normal use. However, severe duty (heavy towing, idling, dusty conditions) might necessitate more frequent changes, possibly around 7,500 miles.
Always replace the oil filter whenever you change the engine oil. The filter plays a crucial role in trapping contaminants and maintaining oil cleanliness.
In conclusion, understanding the specific oil capacity and type for your 2020 Ram 3500’s engine is fundamental to its health and longevity. By adhering to the manufacturer’s recommendations, you’re not just performing routine maintenance; you’re investing in the continued robust performance and reliability of your heavy-duty truck.
