The 2012 Ram 1500 5.7L HEMI V8 is one of the most popular full-size truck engines ever produced. Known for its strong towing capability, durability, and legendary HEMI performance, this engine can easily exceed 200,000 miles when maintained properly.
One of the most important maintenance tasks is using the correct oil type and maintaining the proper oil level. The 5.7 HEMI utilizes Chrysler’s Multi-Displacement System (MDS), which relies heavily on proper oil viscosity and pressure for smooth operation. Using the wrong oil can affect performance, fuel economy, and long-term reliability.
2012 Ram 1500 5.7 Oil Capacity
The 2012 Ram 1500 5.7 HEMI oil capacity is 7 quarts (6.6 liters) when replacing the oil filter. Always verify the final oil level using the dipstick after the engine has run for several minutes and been allowed to sit briefly. The 5.7L HEMI uses a relatively large oil capacity to help manage heat and maintain proper lubrication under heavy loads and towing conditions.
Quick Answer: The 2012 Ram 1500 with the 5.7L HEMI requires exactly 7 quarts of oil with a filter change.
2012 Ram 1500 5.7 Oil Type
Chrysler recommends SAE 5W-20 engine oil that meets MS-6395 specifications. The correct viscosity is important because the HEMI’s Multi-Displacement System (MDS) depends on proper oil flow and hydraulic pressure to deactivate cylinders during highway cruising.
Best Overall Choice: Full synthetic 5W-20 engine oil meeting Chrysler MS-6395 specifications offers superior protection, especially for towing, hot climates, and extended oil change intervals.

2012 Ram 1500 Oil Filter
The factory-recommended oil filter for the 5.7L HEMI is the Mopar MO-899 (or equivalent). Replacing the oil filter at every oil change helps maintain oil pressure and protects the engine from contaminants.
Maintenance Tip: Always lubricate the new filter gasket with fresh oil before installation and hand-tighten according to filter instructions.
2012 Ram 1500 5.7 Oil Change Interval
Although modern synthetic oils can last longer, many HEMI owners perform oil changes every 5,000–7,500 miles for maximum engine protection. Severe-duty use such as towing, frequent idling, and heavy hauling may require shorter intervals.
