Oil Change Interval

For the 2015 Ram 1500, the oil change interval varies based on driving conditions:

• Normal Duty: Under normal driving conditions, the manufacturer recommends an oil change every 8,000 to 10,000 miles or 12 months, whichever comes first. However, always refer to your vehicle's oil change indicator system and owner's manual for the most accurate information.
• Severe Duty: If you frequently operate your truck under severe conditions (e.g., extensive idling, frequent short trips, towing/hauling, dusty conditions, extreme temperatures), an oil change every 4,000 miles or 6 months is recommended to ensure optimal engine protection and longevity.

Drain Plug Torque

• 3.6L Pentastar V6: 20 ft-lbs (27 Nm)
• 5.7L HEMI V8: 25 ft-lbs (34 Nm)
• 3.0L EcoDiesel V6: 30 ft-lbs (40 Nm)

Always use a new crush washer with the drain plug to ensure a proper seal and prevent leaks. Over-torquing the drain plug can strip the oil pan threads, leading to costly repairs.

How to Change the Oil

1. Warm Up Engine: Drive the truck for a few minutes to bring the oil to operating temperature, ensuring it drains more completely.
2. Lift and Secure: Safely lift the front of the truck using a jack and secure it with jack stands. Always use proper safety precautions.
3. Locate Drain Plug: Place an oil drain pan under the oil pan. Remove the drain plug with the appropriate wrench.
4. Drain Oil: Allow all the old oil to drain completely. This can take 10-15 minutes.
5. Replace Drain Plug: Install a new crush washer on the drain plug and tighten it to the specified torque.
6. Remove Oil Filter: Locate the oil filter. For V6 and EcoDiesel engines, the filter is a cartridge type, often located on top of the engine. For the HEMI, it's a spin-on type at the side of the engine block. Unscrew the old filter and allow any residual oil to drain.
7. Install New Filter: Apply a thin film of new oil to the gasket of a spin-on filter (HEMI). For cartridge filters, ensure the new O-rings are seated correctly. Install the new filter, tightening it according to the filter's instructions or until snug (typically hand-tight plus half a turn for spin-on, or to spec for cartridge type).
8. Add New Oil: Lower the truck and remove the oil filler cap. Carefully add the recommended amount and type of new oil.
9. Check Level: Start the engine and let it run for a minute to circulate the oil. Shut it off, wait a few minutes, and then check the oil level with the dipstick. Add more oil if necessary.
10. Inspect for Leaks: Visually inspect the drain plug and oil filter area for any leaks.

Common Issues / Tips

• EcoDiesel Specifics: The EcoDiesel engine requires a specific low-ash synthetic oil (MS-11106 or ACEA C3). Using the wrong oil can damage the emissions system (DPF) and lead to costly repairs. The EcoDiesel also uses a plastic oil filter housing that can be prone to cracking if over-tightened; always use a torque wrench.
• Pentastar and HEMI Oil Coolers: Some 2015 Ram 1500 models with the 3.6L Pentastar V6 or 5.7L HEMI V8 may experience oil cooler leaks, often manifested by oil dripping down the back of the engine. This is a known issue across several Chrysler/Ram platforms. Inspect for leaks around the oil filter housing area for the V6 and near the intake manifold for signs of this issue.
• Oil Consumption (HEMI): Some 5.7L HEMI engines can exhibit higher-than-normal oil consumption. Regularly check your oil level between changes to ensure it stays within the safe operating range.
• Use Quality Filters: Always use high-quality oil filters. Cheap filters may not effectively trap contaminants or may break down, potentially causing engine damage.
• Don't Overfill: Overfilling the engine with oil can cause aeration and foaming, which can lead to reduced lubrication and potential damage. Always stick to the recommended capacity and verify with the dipstick.
