The recommended oil for a 5.7-liter HEMI Ram 1500 is synthetic 5W-20 that meets API SP and ILSAC GF-6 standards. The engine holds about 7 quarts of oil, and you should follow the interval specified in your owner's manual or the vehicle’s oil-life monitor.
The 5.7 HEMI Ram 1500 typically requires 5W-20 synthetic oil, with a capacity of roughly 6.8–7.0 quarts including the filter. In very hot climates or under heavy towing, some model years may allow 5W-30 if the manual permits it, but 5W-20 remains the default baseline. Always check your exact model year’s manual to confirm viscosity, approvals, and capacity.
Viscosity and oil specifications
Here are the core requirements to ensure proper lubrication and warranty coverage.
- Viscosity: 5W-20 synthetic oil is the standard recommendation for most 5.7L HEMI Ram 1500 engines.
- Standards: Oil should be API SP certified and ILSAC GF-6 (GF-6A/B) compliant.
- Alternatives: In certain extreme temperatures or towing scenarios, a 5W-30 may be acceptable if the owner’s manual specifies it for your year/model.
- Oil type: Full synthetic oil is preferred for modern engines to maximize protection and longevity.
Bottom line: Use 5W-20 synthetic oil that meets API SP and ILSAC GF-6 unless your manual allows otherwise.
Oil capacity and change intervals
Knowing the capacity and timing helps plan maintenance and budgeting.
- Engine oil capacity: Approximately 6.8–7.0 quarts (about 6.4–6.6 liters) with a filter for a standard oil change.
- Change interval (synthetic, normal conditions): Typically 7,500–10,000 miles or 12 months, whichever comes first, guided by the vehicle’s oil-life monitor.
- Change interval (conventional or severe service): Often 3,000–5,000 miles under harsher conditions or when using conventional oil.
Always confirm with the owner’s manual and heed the oil-life monitor to tailor the schedule to your driving.
Year-by-year notes and driving considerations
Model-year variations and specific driving conditions may influence the exact recommendations. If you regularly tow heavy loads, live in extreme heat, or drive in stop-and-go city conditions, consult the manual for any year-specific notes and consider using synthetic oil as it tends to hold up better under these stresses. The guidance above reflects current mainstream recommendations for 5.7L HEMI Ram 1500 models from recent years.
Summary
For a 5.7 HEMI Ram 1500, the standard oil choice is synthetic 5W-20 meeting API SP and ILSAC GF-6 standards, with about 7 quarts capacity and maintenance intervals guided by the owner’s manual or the vehicle’s oil-life monitor. Always verify the exact specifications for your model year and climate, and follow the recommended oil change schedule.
