Why MS-6395 0W-20 is Critical
The 3.6L Pentastar V6 uses Variable Valve Timing (VVT) and Multi-Air technology. It requires Chrysler MS-6395 certified oil for:
- Proper VVT solenoid operation
- Protection against start-up wear
- Maintaining fuel economy
Using incorrect oil (like 5W-30) can lead to Check Engine Lights (P06DD) and VVT issues. Note: This spec applies to both the outgoing WK2 generation and the new WL Grand Cherokee L introduced in 2021.
