Recommended oil type and change guidance
Viscosity and specifications
For the 2006 Commander 5.7L Hemi, the recommended viscosity is typically 5W-20 in normal climates, with 5W-30 acceptable in hotter climates or for severe service. Use motor oil that meets Chrysler MS-6395 specification and API SN (or newer) standards. Full synthetic is acceptable and often preferred for protection and longevity.
Change interval and maintenance notes
Standard oil-change intervals for this engine, using conventional 5W-20 or 5W-30 oil, are generally every 3,000–5,000 miles (4,800–8,000 kilometers) depending on driving conditions, with synthetic oils often allowing longer intervals per the owner's manual or dealer guidance. Always consult the 2006 Commander owner's manual for exact recommendations for your climate and usage.
Practical tips for service
When you’re ready to change oil, gather the following to ensure a clean, proper job: the correct oil type and quantity, a new oil filter, an appropriate drain pan, a filter wrench, and a torque wrench to tighten the drain plug to specification. After filling, run the engine briefly and recheck the level on the dipstick to ensure accuracy.
Summary
The 2006 Jeep Commander with a 5.7L Hemi takes about 7 quarts (roughly 6.6 liters) of engine oil with the filter, and about 6 quarts (roughly 5.7 liters) without the filter. Use the recommended viscosity (5W-20 or 5W-30) and a current API/MS-6395 specification oil, and follow your manual for change intervals. Always verify the level after a change and top off to the full mark.
