The 2013 Ram 1500 with a 5.7-liter HEMI uses SAE 5W-20 engine oil, in either a synthetic blend or full synthetic, that meets Chrysler MS-6395 and API SN or newer. The engine’s oil capacity is about 7 quarts with a filter. Always verify the exact specification on your vehicle’s manual or filler cap.
Official oil specification
Chrysler’s guidance for the 2013 Ram 1500 5.7 HEMI calls for 5W-20 viscosity as the baseline grade. Oils that meet the MS-6395 specification and API SN (or newer) are suitable for this engine, and manufacturers commonly offer both synthetic blend and full-synthetic options that comply with these standards.
Below are the acceptable oil options that align with the OEM requirements:
- 5W-20 synthetic blend that meets MS-6395 and API SN or newer
- 5W-20 full synthetic that meets MS-6395 and API SN or newer
When selecting oil, always ensure the product explicitly states MS-6395 certification and a current API service rating.
Oil capacity and maintenance intervals
The 5.7 HEMI engine in this truck holds about 7 quarts (roughly 6.6–7.0 quarts depending on the filter installed) of engine oil. Oil-change intervals vary with driving conditions and oil type, but with synthetic oils, many owners schedule changes roughly every 7,500 miles or as recommended in the owner’s manual. Severe driving conditions, frequent short trips, or extreme temperatures can shorten intervals, so always follow the manual’s guidance for your situation.
Climate considerations
Cold weather starting and winter driving
In colder climates, 5W-20 provides better cold-start lubrication and quicker engine protection at startup. Both synthetic blend and full synthetic 5W-20 options are appropriate, as long as they meet MS-6395 and API SN.
Hot weather and heavy use
In hot climates or for vehicles regularly carrying heavy loads or towing, the 5W-20 grade remains the baseline recommendation, but you should monitor oil temperature and consumption. If a higher-temperature driving pattern is common, consult your dealer or the manual for any climate-specific notes, though 5W-20 is typically acceptable.
Summary
For a 2013 RAM 1500 with a 5.7 HEMI, use SAE 5W-20 engine oil, either synthetic blend or full synthetic, that meets Chrysler MS-6395 and API SN or newer. The engine capacity is about 7 quarts with a filter, and oil-change intervals should follow the owner’s manual, with adjustments for driving conditions and climate. Always verify the exact specification on the filler cap or in the manual to ensure full compatibility.
