The 3.6L Ram 1500 typically uses about 6 quarts of engine oil with the filter installed (roughly 5.7 quarts to reach the full mark on the dipstick).
In practice, oil capacity for the 3.6 Pentastar can vary slightly by model year, any added oil cooler, and whether you’re performing a full oil change with filter replacement. This article outlines the typical capacity and how to confirm the exact amount for your truck.
Typical oil capacity for the 3.6L V6 in Ram 1500
The figures below reflect common configurations used in Ram 1500 pickups with the 3.6L V6. They assume you replace the oil filter and drain the pan as part of a routine change. Always verify with your owner's manual for your exact year/model.
- Oil capacity with filter installed: approximately 6 quarts (roughly 5.7 quarts to the full line on the dipstick).
- Oil capacity without the filter: about 5 quarts.
- Notes: Some engines with an auxiliary oil cooler or larger filters can differ by a small amount; always verify with the owner's manual or a service bulletin for your exact year/model.
When performing an oil change, a practical approach is to start with 6 quarts, run the engine briefly, then turn it off and let it settle for 5–10 minutes before rechecking the dipstick. Add oil in small increments if needed until the level is at or near the full mark.
Other considerations for oil type and maintenance
Use the viscosity recommended by your owner’s manual, typically 5W-20 or 0W-20 depending on climate and year. Choose a high-quality motor oil that meets API specifications and Mopar/Chrysler requirements. Regular oil changes are essential for the long-term performance of the 3.6L Pentastar.
Summary
For most Ram 1500 trucks with the 3.6L Pentastar, expect about 6 quarts of oil with the filter installed (about 5.7 quarts to the full line). Always confirm the exact capacity for your specific year and configuration by consulting the owner’s manual or service guide, and follow the recommended oil viscosity for your climate.
