2020 Ram 5.7 oil capacity and type are crucial pieces of information for any owner looking to properly maintain their truck’s legendary 5.7L HEMI V8 engine. Understanding these specifications is not just about keeping your engine running; it’s about optimizing its performance, ensuring its longevity, and maintaining its fuel efficiency. Whether you’re a seasoned DIY mechanic or planning your next service appointment, knowing the precise requirements for your Ram’s heart is a fundamental aspect of responsible vehicle ownership.
Understanding Your 2020 Ram 5.7L Hemi Engine
The 5.7L HEMI V8 engine found in the 2020 Ram 1500 is a powerhouse, renowned for its robust performance, towing capability, and distinct exhaust note. This engine features advanced technologies such as Variable Valve Timing (VVT) and, in some configurations, the Multi-Displacement System (MDS), which allows the engine to deactivate cylinders under light load for improved fuel economy. These sophisticated systems rely heavily on the proper type and amount of engine oil to function correctly and prevent premature wear. Using the wrong oil can lead to decreased performance, increased wear, and potentially costly repairs down the road.
Decoding the 2020 Ram 5.7 Oil Capacity
Getting the oil level just right is as important as using the correct oil type. Too little oil can lead to insufficient lubrication and overheating, while too much can cause aeration (foaming) and damage to seals and other components.
For the 2020 Ram 1500 equipped with the 5.7L HEMI V8 engine, the 2020 Ram 5.7 oil capacity is 7 quarts (or approximately 6.6 liters) when the oil filter is also replaced.
It’s vital to remember that this capacity is a general guideline. Always perform the following steps after an oil change:
1. Add 6.5 quarts (or 6.2 liters) of the recommended oil.
2. Start the engine and let it run for a minute or two to circulate the new oil and fill the filter.
3. Turn off the engine and wait a few minutes for the oil to settle back into the oil pan.
4. Carefully check the oil level using the dipstick. The level should be between the “MIN” and “MAX” marks.
5. Add small amounts of oil (typically 0.1-0.2 quarts) as needed until the level is at or near the “MAX” mark, without exceeding it.
Regularly checking your oil level between changes, especially before long trips, is an excellent habit. Park your truck on a level surface, allow the engine to cool for at least 10-15 minutes, then withdraw the dipstick, wipe it clean, reinsert it fully, and withdraw it again to get an accurate reading.
Choosing the Right Oil Type for Your 2020 Ram 5.7 Hemi
The type of oil you use in your 2020 Ram 5.7L HEMI engine is specified by the manufacturer to meet precise lubrication and protection standards. Deviating from these recommendations can void your warranty and jeopardize engine health.
For the 2020 Ram 1500 with the 5.7L HEMI V8 engine, the recommended oil type is:
Viscosity: SAE 5W-20
Specification: It must meet or exceed Chrysler Material Standard MS-6395.
Let’s break down what this means:
1. SAE 5W-20:
The “5W” indicates the oil’s viscosity (thickness) at cold temperatures (“W” stands for Winter). A lower number means the oil is thinner when cold, allowing it to flow more easily and quickly lubricate engine components during start-up, especially in colder climates.
The “20” indicates the oil’s viscosity at normal operating temperatures. This higher number ensures adequate protection when the engine is hot and working hard.
Using a different viscosity than 5W-20 can impact the proper operation of the VVT and MDS systems, potentially leading to reduced fuel economy or even engine damage.
2. Chrysler Material Standard MS-6395:
This is a critical specification. It signifies that the oil has been rigorously tested and certified by Chrysler (now Stellantis) to meet the specific demands and characteristics of their engines. Many reputable oil brands offer products that meet or exceed this standard. Always look for “Meets or Exceeds Chrysler MS-6395” on the oil bottle.
Using an oil that does not carry this certification, even if it has the correct viscosity, may not provide the necessary protection against wear, sludge buildup, and oxidation.
Synthetic vs. Conventional vs. Blend:
While the standard does not always explicitly require full synthetic, many owners and experts recommend using a full synthetic 5W-20 oil that meets the MS-6395 standard. Full synthetic oils generally offer superior protection, better flow at extreme temperatures, and extended oil change intervals compared to conventional oils. They are especially beneficial for engines like the HEMI that experience varied loads and temperatures, and for vehicles that tow frequently.
The Critical Role of Proper Lubrication for Your Hemi
Your Ram’s engine oil does more than just lubricate moving parts; it plays several vital roles:
Cooling: It helps dissipate heat away from critical engine components.
Cleaning: It carries away contaminants, metal particles, and sludge, keeping the engine clean.
Sealing: It provides a seal between the piston rings and cylinder walls.
Corrosion Protection: It contains additives that prevent rust and corrosion.
Hydraulic Function: It is essential for the operation of hydraulic components like the VVT system and hydraulic lifters.
Using the correct oil capacity and type ensures these functions are performed optimally, safeguarding your investment and keeping your Ram 1500 performing at its best.
Maintaining Your Ram’s Oil: Checking and Changing
Regular oil changes are the backbone of engine maintenance. For the 2020 Ram 1500 5.7L, always refer to your owner’s manual for the most accurate service intervals. Many modern Rams utilize an “Oil Change Indicator System” which monitors driving conditions and calculates when an oil change is due. This system is generally reliable, but a good rule of thumb is:
Conventional Oil: Every 3,000-5,000 miles (approx. 4,800-8,000 km) or 3-6 months.
Synthetic Oil (MS-6395 certified): Often allows for longer intervals, typically 7,500-10,000 miles (approx. 12,000-16,000 km) or 6-12 months, depending on driving conditions and manufacturer recommendations.
When changing the oil, always replace the oil filter with a quality filter specified for your 2020 Ram 5.7L HEMI. A good filter is just as important as good oil for trapping contaminants.
Conclusion
Paying attention to the 2020 Ram 5.7 oil capacity and type is a small effort with significant returns for your truck. By ensuring you use the correct 7 quarts of SAE 5W-20 oil that meets the Chrysler MS-6395 specification, you are providing your HEMI engine with the precise lubrication it needs to deliver power, efficiency, and reliability for years to come. Always consult your owner’s manual for the definitive recommendations and consider using a full synthetic oil for optimal protection. Your Ram will thank you for it!
