2019 Ram 1500 5.7 Oil Capacity: Full Guide & Specs

The 2019 Ram 1500 with the 5.7L HEMI V8 remains a benchmark for power and durability in the full-size truck segment. One of the most frequently asked questions among owners and enthusiasts is: what is the correct 5.7L oil capacity for this model? Answering this helps prevent performance issues, ensures proper lubrication, and supports long engine life. This guide covers everything you need to know about oil capacity, compatibility, and maintenance for the 2019 Ram 1500 5.7.

Understanding the 5.7L Engine and Its Oil Requirements

The 5.7L HEMI V8 engine, introduced in 2011, powers most 2019 Ram 1500 models and delivers impressive torque and horsepower. To maintain peak efficiency, the engine relies on precise oil volume. Using incorrect oil capacity—whether underfilling or overfilling—can cause overheating, increased wear, or sludge buildup.

The standard 5.7L HEMI engine uses 6 quarts (6.0L) of 5W-30 or 5W-40 synthetic oil, depending on manufacturer recommendation and regional climate. This capacity aligns with the vehicle’s oil pump design and piston ring sealing requirements. Some aftermarket service centers may specify 6.5 quarts, but this is often unnecessary and can lead to oil splashing or improper pressure.

Oil Capacity Variations and Key Considerations

While 6 quarts is the factory standard, a few factors may influence oil volume slightly:

  • Engine Tuning: Modified or performance-tuned engines sometimes require adjusted oil capacity for optimal heat dissipation, though this is rare in stock 2019 Ram 1500s.
  • Climate: In extreme heat, higher oil capacity may improve cooling, but exceeding 6.5 quarts is not advised without professional consultation.
  • Oil Type: Synthetic blends perform consistently within the 6L range and are recommended for modern engines like the 2019 Ram 5.7. Always use oil meeting API SN or higher standards.

For reliable engine health, stick to synthetic 5W-30 or 5W-40 oil from trusted brands such as Mobil 1, Pennzoil, or Valvoline. These oils maintain viscosity under high heat, resist oxidation, and reduce engine deposits. Avoid conventional oils unless specified, as they may not protect the 5.7L HEMI adequately.

Maintenance Tips for Optimal Performance

To keep your Ram 1500’s 5.7L engine running smoothly:

  • Always perform oil changes every 5,000–7,500 miles using the correct 6L capacity.
  • Check oil level regularly using the dipstick—engine is at operating temperature for accurate reading.
  • Inspect for leaks around the oil pan and gaskets; address promptly.
  • Use a high-quality oil filter compatible with the 2019 Ram 5.7 engine.
