The Ram 5.7 HEMI V8 is one of the most iconic truck engines ever built, known for strong torque, towing capability, and long-term durability. It powers the Ram 1500, Dodge Charger, Challenger, Jeep Grand Cherokee, and Chrysler 300.
Proper oil selection is critical for the HEMI engine because it uses the Multi-Displacement System (MDS), which depends heavily on correct oil pressure and lubrication quality. Using the wrong oil can lead to lifter noise, reduced performance, and long-term engine wear.
What Type of Oil Does Ram 5.7 HEMI Use?
The recommended oil type for the Ram 5.7 HEMI is based on Chrysler’s MS-6395 specification. This ensures proper lubrication for MDS lifters and VVT components.
- Factory Recommended Oil: SAE 5W-20 full synthetic
- Alternative (heavy towing): SAE 5W-30
- Cold Climate Option: SAE 0W-20 (newer models)
- Oil Standard: Chrysler MS-6395 approved oil
Ram 5.7 HEMI Engine Oil Capacity
Correct oil capacity is important for maintaining oil pressure and preventing engine damage.
- Oil Capacity (with filter): 7 quarts (approx. 6.6 liters)
- Oil Capacity (without filter): ~6.5 quarts
Always verify final oil level using the dipstick after filling, as small variations can occur depending on filter type.
