2019 Dodge Ram 5.7 oil capacity and type are crucial pieces of information for any owner looking to properly maintain their truck’s legendary Hemi engine. Understanding these specifications ensures optimal engine performance, longevity, and efficiency, preventing potential issues down the road. For many Ram owners across the USA and Canada, their truck is more than just a vehicle – it’s a workhorse, a family hauler, and an investment. Therefore, giving it the right care, starting with the correct engine oil, is paramount.
Why Engine Oil is the Lifeblood of Your Ram’s Hemi
Engine oil plays a multifaceted role in the health of your 5.7L Hemi V8. It’s not just about lubrication; it performs several vital functions:
Lubrication: It reduces friction between moving parts, preventing wear and tear.
Cooling: It helps dissipate heat generated by combustion and friction.
Cleaning: It carries away contaminants, sludge, and microscopic particles, keeping the engine clean.
Sealing: It creates a seal between the pistons and cylinder walls, preventing combustion gases from escaping.
Corrosion Protection: It protects engine components from rust and corrosion.
Using the correct oil type and capacity ensures these functions are carried out effectively, allowing your Hemi to run smoothly for hundreds of thousands of miles.
Understanding the 2019 Dodge Ram 5.7 Oil Capacity
For the 2019 Dodge Ram equipped with the venerable 5.7-liter Hemi V8 engine, the oil capacity is a well-defined specification that drivers should always adhere to.
The 2019 Dodge Ram 5.7 oil capacity is 7 quarts (approximately 6.6 liters) when performing an oil and filter change. This capacity is critical because both under-filling and over-filling can lead to serious engine problems.
Under-filling: Not enough oil can lead to insufficient lubrication, increased friction, higher engine temperatures, and accelerated wear on vital components. This can quickly result in catastrophic engine failure.
Over-filling: Too much oil can cause the crankshaft to churn or “aerate” the oil, creating foam. This foamy oil doesn’t lubricate effectively, leading to reduced oil pressure, potential seal damage, and even catalytic converter issues due to oil being forced into the combustion chamber.
Always use your dipstick as the final confirmation after an oil change. Run the engine for a few minutes, shut it off, wait for the oil to settle (5-10 minutes), and then check the level. It should fall within the “full” or safe operating range markings on the dipstick.
Optimal Oil Type for Your 2019 Dodge Ram 5.7
Beyond capacity, selecting the correct oil type is equally important. Modern engines like the 5.7L Hemi are designed to operate with specific oil viscosities and formulations.
For the 2019 Dodge Ram 5.7L Hemi, the manufacturer strongly recommends using SAE 5W-20 full synthetic motor oil.
Here’s a breakdown of what that means:
SAE 5W-20: This is the oil’s viscosity grade.
“5W” indicates its performance in cold weather (“W” stands for winter). A lower number means better cold-start performance and easier flow in freezing temperatures.
“20” indicates its viscosity at normal operating temperatures.
This specific viscosity ensures proper lubrication at startup and maintains optimal film strength when the engine is hot, especially considering the Hemi’s design features like the Multi-Displacement System (MDS).
Full Synthetic: While conventional oils were once the norm, synthetic oils offer superior protection and performance. They are engineered to:
Resist thermal breakdown better than conventional oils.
Provide enhanced protection against wear.
Flow more easily in cold weather, reducing engine wear during startup.
Offer better cleaning properties, preventing sludge and deposit buildup.
Maintain viscosity stability over a wider range of temperatures.
Chrysler MS-6395 Specification: This is a crucial detail. The oil you choose must meet the Chrysler MS-6395 material specification. This certification ensures the oil has undergone rigorous testing and meets Dodge/Ram’s specific performance and protection requirements for the Hemi engine. Look for this specification printed on the oil bottle. Brands like Pennzoil Ultra Platinum, Mobil 1, Valvoline, Castrol, and Mopar often carry this certification.
Using an oil that doesn’t meet the MS-6395 specification, or one with an incorrect viscosity, can compromise engine protection, potentially void your warranty, and lead to premature wear or other engine complications.
Oil Change Frequency for Your 2019 Ram
While the type and capacity are fixed, the frequency of oil changes can vary. Modern Ram trucks are equipped with an advanced engine oil change indicator system. This system monitors various operating conditions, such as engine temperature, speed, and time, to determine when an oil change is necessary.
Generally, you should follow the oil change indicator on your dashboard, which typically recommends an oil change between 3,500 and 10,000 miles or every 6 to 12 months, whichever comes first. However, driving conditions play a significant role:
Severe Driving Conditions: Frequent short trips, extensive idling, towing heavy loads, off-road driving, or driving in extremely dusty or cold conditions will necessitate more frequent oil changes, possibly closer to the 3,500-5,000 mile range.
Normal Driving Conditions: Highway driving with consistent speeds and moderate temperatures allows for longer intervals.
Always consult your owner’s manual for the most accurate and specific recommendations for your 2019 Ram 5.7. Regular oil and filter changes, coupled with the correct oil type and capacity, are the most effective ways to ensure your Hemi engine delivers reliable performance for years to come.
Common Oil Maintenance Mistakes to Avoid
Ignoring the Oil Change Indicator: Don’t delay an oil change once the system alerts you.
Using the Wrong Viscosity: Sticking to 5W-20 is paramount for the 5.7L Hemi.
Forgetting the MS-6395 Spec: This certification isn’t optional; it’s a requirement for proper engine protection.
Not Changing the Oil Filter: A new filter is just as important as new oil. Always replace it with a quality filter that meets OEM specifications.
Over- or Under-filling: Always double-check the dipstick.
Mixing Oil Types: While generally not harmful in small amounts, it’s best to stick to one type (e.g., full synthetic) for optimal performance.
By paying close attention to the 2019 Dodge Ram 5.7 oil capacity and type, you’re taking a proactive step in preserving the powerful and dependable heart of your truck. It’s a small investment in time and money that pays significant dividends in engine longevity and peace of mind.
