The 4.7L Jeep Grand Cherokee typically uses 5W-30 engine oil that meets API standards and Chrysler’s MS-6395 specification; capacity is about 7 quarts with a filter, and you should confirm the exact grade and amount in your owner's manual or on the engine oil fill cap.
Understanding the 4.7L PowerTech engine oil needs
The 4.7L PowerTech V8 found in older Grand Cherokees has a fairly consistent oil requirement, with slight climate-based adjustments in some model years. Using the correct viscosity and a compatible spec is important for proper lubrication and engine longevity.
Recommended oil viscosity and specifications
Keep in mind the typical guidance and where to check for your specific vehicle. The following options are common across many 4.7L Grand Cherokees:
- 5W-30 engine oil that meets API SN/SM and Chrysler MS-6395 specification (gasoline engines).
- In colder climates or if your manual specifically allows it, 5W-20 may be used provided it also meets the MS-6395 spec.
- Avoid thicker oils such as 10W-40 unless explicitly approved by your owner's manual or service documentation for your year/model.
Verifying the exact grade for your vehicle is essential, as some model years or regional specs may differ. Always cross-check the label under the hood and in your owner's manual.
Oil capacity and service interval
Knowing how much oil your engine holds and how often to change it helps ensure optimal performance and longevity.
- Oil capacity: Approximately 6.5–7 quarts (about 6.2–6.6 liters) with a filter for many 4.7L Grand Cherokees; exact capacity can vary by year and filter type.
- Change interval with conventional oil: roughly every 3,000–5,000 miles (4,800–8,000 km) depending on driving conditions and manufacturer guidance.
- Change interval with synthetic oil: roughly every 5,000–7,500 miles (8,000–12,000 km), again depending on use and manual recommendations.
Consult the owner's manual for the precise interval and any “severe service” conditions that might shorten the recommended change schedule.
How to verify the exact specification for your vehicle
Since the 4.7L engine has seen multiple model years and regional specifications, the safest approach is to confirm the exact oil grade and capacity for your specific Jeep. The oil fill cap may list the grade, and the under-hood sticker often reiterates the recommended viscosity and spec. If in doubt, your dealership or a trusted mechanic can pull the exact specification from the VIN-specific service data.
How to choose and apply the right oil
- Always choose oil that meets API service classification and Chrysler MS-6395 for this engine.
- Prefer synthetic or synthetic-blend oils if you drive in extreme temperatures or want longer intervals, provided your manual supports it.
- Use a quality oil filter from a reputable brand or Mopar filter, and replace the drain plug gasket if required.
Bottom line: default to 5W-30 with MS-6395 unless your manual specifies 5W-20 or another grade, and follow the recommended change interval for your driving conditions.
Summary
For a 4.7L Jeep Grand Cherokee, the standard oil choice is 5W-30 that meets API SN/SM and Chrysler MS-6395, with an approximate capacity near 7 quarts including the filter. Always verify your exact grade and capacity in the owner's manual or on the vehicle’s under-hood label, and adjust for climate and driving conditions. Synthetic oils generally offer longer change intervals, but defer to the manual for your specific year and configuration. Regular, correct oil changes are essential to keep the 4.7L PowerTech running smoothly.
