The 2019 Ram 5.7 oil capacity and type are crucial pieces of information for any owner looking to properly maintain their truck’s potent Hemi engine. Understanding these specifications ensures optimal engine performance, longevity, and reliability, preventing costly issues down the road. The 5.7-liter Hemi V8 is a workhorse, known for its power and durability, but like any sophisticated piece of machinery, it demands adherence to manufacturer guidelines for its essential fluids.
Understanding Your 2019 Ram 5.7 Hemi Oil Capacity
For the 2019 Ram 1500 equipped with the 5.7L Hemi V8 engine, the specified engine oil capacity is 7 quarts (6.6 liters). This measurement includes the oil filter. It’s vital to note this capacity because overfilling or underfilling your engine oil can lead to significant problems.
Underfilling: Running with insufficient oil can cause inadequate lubrication, leading to excessive friction, overheating, and premature wear on critical engine components. This can result in severe engine damage.
Overfilling: While seemingly less harmful, overfilling can also cause issues. Too much oil can be churned into a foam by the crankshaft, reducing its lubricating effectiveness. It can also lead to increased oil pressure, potentially damaging seals and gaskets, and even causing oil to enter the combustion chamber, leading to blue smoke from the exhaust and carbon buildup.
Always check your oil level on a flat surface after the engine has been turned off for at least 5-10 minutes (allowing oil to drain back into the pan). The dipstick provides a clear indication of the proper range, usually marked with “MIN” and “MAX” lines or a safe operating zone.
Choosing the Right Oil Type for Your 2019 Ram 5.7
Selecting the correct oil type is just as important as knowing the capacity. The 2019 Ram 5.7L Hemi V8 engine requires a specific viscosity grade and must meet a particular material standard.
Chrysler (now Stellantis) recommends using SAE 5W-20 full synthetic engine oil. More importantly, the oil must meet the Chrysler Material Standard MS-6395. This standard ensures the oil contains the necessary additives and properties to protect your Hemi engine effectively, especially given its advanced features like Variable Valve Timing (VVT) and the Multi-Displacement System (MDS).
Why SAE 5W-20?
The “5W” refers to the oil’s viscosity when cold (“W” for winter). A lower number means the oil is thinner at cold temperatures, allowing it to flow more easily and lubricate engine parts quickly during startup. This is crucial for reducing wear, especially in colder climates. The “20” refers to the oil’s viscosity at operating temperature. A higher number would indicate a thicker oil. The 5W-20 balance is engineered to provide optimal protection across a wide range of operating temperatures for the Hemi.
Why Full Synthetic and MS-6395?
Modern engines like the Hemi operate at tighter tolerances and higher temperatures, and they feature technologies like MDS (which deactivates cylinders for fuel efficiency). Full synthetic oils offer superior protection compared to conventional or synthetic blends. They are more stable, resist breakdown better under extreme heat, provide enhanced lubrication, and flow more efficiently in cold weather. The MS-6395 standard guarantees that the oil’s additive package is specifically designed to interact correctly with the Hemi’s internal components, protecting against wear, sludge, and varnish formation.
Many reputable oil brands offer 5W-20 full synthetic oils that meet the MS-6395 specification, including Pennzoil Ultra Platinum, Valvoline SynPower, Mobil 1, and Royal Purple. Always check the product label for the “MS-6395” certification.
The Importance of Regular Oil Changes
Adhering to the manufacturer’s recommended oil change intervals is paramount for the health of your 2019 Ram 5.7. While synthetic oils offer extended service life, they don’t last forever. The general recommendation for the 2019 Ram 5.7 Hemi is to change the oil and filter every 8,000 to 10,000 miles or every 6-12 months, whichever comes first.
However, these intervals can vary based on your driving conditions:
Heavy-Duty Use: If you frequently tow heavy loads, drive in dusty conditions, or engage in extensive stop-and-go city driving, you might need more frequent oil changes (e.g., every 5,000 miles or 6 months).
Extreme Temperatures: Driving in very hot or very cold climates can also put additional stress on your engine oil, warranting shorter intervals.
* Oil Life Monitoring System: Your 2019 Ram 1500 is equipped with an Oil Life Monitoring (OLM) system that analyzes driving conditions and engine parameters to determine the optimal time for an oil change. While a useful tool, it’s generally best to not exceed 10,000 miles or one year, even if the OLM suggests more.
Regular oil changes ensure that your engine always has clean, properly formulated oil to lubricate, cool, and protect its vital components. Over time, engine oil breaks down, loses its viscosity, and accumulates contaminants like dirt, metal particles, and combustion byproducts, reducing its effectiveness.
The Role of a Quality Oil Filter
Don’t overlook the importance of a high-quality oil filter. The oil filter removes contaminants from the engine oil, preventing them from circulating and causing damage. A cheap or incorrect filter can fail to adequately clean the oil or restrict flow, compromising engine lubrication. Always use a filter that meets or exceeds the OEM specifications for your 2019 Ram 5.7 Hemi. Mopar brand filters are always a safe bet, as are reputable aftermarket brands like Wix, Mann, or Bosch, which are designed to meet manufacturer standards.
Ensuring Your Hemi’s Longevity
Paying close attention to the 2019 Ram 5.7 oil capacity and type, along with adhering to regular maintenance schedules, is fundamental to getting the most out of your truck. These details, though seemingly small, collectively contribute to the immense performance and durability that the Hemi engine is known for. By using the correct amount of the right oil and changing it diligently, you’re not just performing routine maintenance; you’re investing in the long-term health and efficiency of your valuable Ram pickup.
