How much oil does a RAM 1500 5.7 Hemi take?
The 5.7-liter Hemi in a RAM 1500 typically requires about 7 quarts (approximately 6.6 liters) of engine oil when you replace the oil filter, and about 6 quarts (roughly 5.7 liters) if you do not replace the filter. Always check your owner’s manual or a dealer for the exact figure for your year and configuration.
Oil capacity overview
Understanding the capacity means noting that the total quantity can differ depending on whether the oil filter is changed during an oil service. The figures below reflect common specifications for the 5.7L Hemi used in RAM 1500 pickups, but variations can occur by model year, engine code, and filter size.
Before listing the standard capacity figures, it’s important to clarify the two common scenarios you’ll encounter during an oil change.
- With a new oil filter installed: 7 quarts (about 6.6 liters).
- Without replacing the filter: 6 quarts (about 5.7 liters).
These numbers align with typical service specs published by RAM (Chrysler) for the 5.7L Hemi in the RAM 1500. Always verify with your vehicle’s manual or a trusted dealer, as a different filter size or engine revision can adjust the exact amount.
Oil type and maintenance considerations
Recommended oil viscosity and type
For most RAM 1500 5.7 Hemi engines, the recommended viscosity is 5W-20 for standard temperatures, with 5W-30 acceptable in hotter climates or under heavy towing. Use a quality engine oil that meets or exceeds Chrysler’s approvals and the API/Synonyms listed in your manual. Synthetic or synthetic-blend oils are common choices for longevity and protection.
When selecting oil, always follow the specifications in the owner’s manual, including the certification (such as API SN/Resource or equivalent) and the correct viscosity for your climate and driving conditions.
Oil change intervals and practical tips
Oil change intervals depend on oil type, driving conditions, and the vehicle’s onboard maintenance reminders. Synthetic oils often allow longer intervals, but in severe service (extreme temps, heavy towing, or frequent short trips), more frequent changes may be appropriate. Always reset the vehicle’s maintenance minder after an oil change and record the mileage at service.
How to apply these figures to your service
When you’re preparing to change the oil on a RAM 1500 with a 5.7 Hemi, plan around the following practical steps: verify the exact oil capacity in your manual, choose the appropriate oil and filter, drain the old oil completely, replace the oil filter if specified, refill with the total capacity (7 quarts with filter or 6 quarts without), and recheck oil level with the dipstick after running the engine and letting it settle.
Bottom line: the standard oil capacity for a RAM 1500 5.7 Hemi is about 7 quarts with a new filter and about 6 quarts without a filter. Confirm the exact figure for your specific model year and configuration to ensure a precise oil fill.
Summary
For most RAM 1500 models equipped with the 5.7 Hemi, you’ll need roughly 7 quarts of engine oil when changing the filter, or about 6 quarts if you’re not replacing the filter. Use the recommended viscosity (typically 5W-20, sometimes 5W-30 in certain climates) and always consult your owner's manual for year-specific specs. Regular oil changes, accurate fills, and proper filter replacement are key to maintaining engine health.
