Challenger Oil Change DIY: Complete Guide for 5.7L, 6.4L, and 6.2L

Oil Specs by Engine

| Engine | Oil Type | Viscosity | Capacity |

|---|---|---|---|

| 5.7L HEMI | Full synthetic | 5W-20 | 7 quarts |

| 6.4L HEMI | Full synthetic | 5W-20 | 7 quarts |

| 6.2L Hellcat | Full synthetic | 0W-40 | 7 quarts |

Recommended oils: Pennzoil Platinum, Mobil 1, Valvoline Full Synthetic. Mopar recommends API SP / ILSAC GF-6A rated oils.

The Hellcat specifically requires 0W-40 — don't substitute with 5W-20 or 5W-30 on the supercharged engine.

Change Intervals

• Normal driving: 10,000 miles or 1 year with full synthetic
• Severe service (track, extreme temps, short trips): 5,000 miles
• Mopar max recommendation: Every 10,000 miles per oil life monitor

Tools and Parts

• Oil drain pan
• 15mm socket (drain plug)
• Oil filter wrench (cap-style for the HEMI's cartridge filter)
• Funnel
• 7 quarts of approved oil
• New oil filter (Mopar MO-090, Wix 57502, or equivalent)

Note: The HEMI uses a cartridge-style oil filter (not a spin-on) mounted on top of the engine. It's much easier to access than spin-on filters under the car.

Step-by-Step

1. Warm the engine (2–3 minutes) — warm oil drains faster
2. Raise the car on jack stands or drive onto ramps
3. Remove the engine undertray if present (plastic clips or screws)
4. Position drain pan under the drain plug (passenger-side rear of the oil pan)
5. Remove drain plug with 15mm socket — let oil drain fully (5–10 minutes)
6. Replace drain plug with new washer — torque to 20 ft-lb (don't overtighten on aluminum pan)
7. From the top of the engine, remove the oil filter housing cap with a 36mm socket or cap wrench
8. Remove the old filter cartridge — replace with new filter
9. Reinstall cap — torque to 18 ft-lb
10. Fill with 7 quarts of correct oil via the fill cap on top of the engine
11. Start and idle for 2 minutes — check for leaks
12. Check oil level on dipstick — add if needed
13. Reset the oil life monitor (hold the oil can icon on the instrument cluster)
