A RAM 1500 with the 5.7L Hemi typically takes about 7 quarts (6.6 liters) of engine oil when performing a full oil change with a new filter.
In practice, capacity can vary slightly by model year and whether you replace the oil filter. The figures below cover the standard ranges and how to apply them when planning an oil service.
Typical oil capacity (with and without filter)
The following figures cover common configurations across RAM 1500 5.7L Hemi engines.
- 7 quarts (6.6 liters) of engine oil with the oil filter replaced.
- 6 quarts (5.7 liters) if you drain only the oil and do not replace the filter.
These figures are typical for most model years, but always verify with your owner’s manual or the service sticker under the hood for your exact vehicle and VIN.
Recommended oil type and grade
The RAM 1500 5.7L Hemi generally calls for a synthetic oil of a light viscosity, with the most common specification guidance as follows. Check your year and climate to confirm the exact requirement.
- 5W-20 synthetic is the standard recommendation for many RAM 1500 5.7L engines; 0W-20 may be advised in extremely cold climates.
- Use a Mopar/Chrysler-approved full synthetic oil that meets the manufacturer’s specification and current API service category; your manual will specify the exact approval level.
When in doubt, follow the oil grade and capacity listed in your owner’s manual and confirm any year-specific notes with a dealer or trusted service center.
Oil change tips and how to check the oil level
Follow these steps to perform a proper oil change and to verify the level after adding oil.
- Warm up the engine briefly to circulating temperature, then turn it off and let it settle.
- Place a drain pan beneath the oil pan and remove the drain plug to let the old oil flow out completely.
- Remove and replace the oil filter with a new one, ensuring a proper seal.
- Reinstall the drain plug and add the recommended amount of new oil (about 7 quarts with a new filter, adjust if your manual specifies a different amount).
- Check the oil level with the dipstick on a level surface: wipe the dipstick, reinsert, then pull it out to verify the level is within the marked range. Add oil in small increments if needed.
- Run the engine for a minute, recheck for leaks, and verify the final oil level again after the engine is off for a few minutes.
- Dispose of used oil and the oil filter properly at an appropriate recycling facility or service center.
Keeping the correct oil quantity and grade helps protect the engine and maintain optimal performance. Always consult your manual and follow local regulations when disposing of used oil.
Summary
For the RAM 1500 with the 5.7L Hemi, plan for about 7 quarts (6.6 liters) of engine oil during a standard oil change with a new filter, with about 6 quarts (5.7 liters) if you’re not replacing the filter. Use a synthetic oil that meets the manufacturer’s specifications (commonly 5W-20 or 0W-20, depending on year and climate). Verify exact capacity and grade in your owner’s manual, and follow proper changing procedures to ensure engine longevity.
