Complete Oil Specifications
The owner’s manual for the 2023 Jeep Grand Wagoneer recommends Mopar API Certified SAE 0W-40 Full Synthetic Engine Oil meeting Material Standard MS-A0921; an equivalent full synthetic SAE 0W-40 oil can be used but must have the API Donut trademark for the 6.4L engine. Engine oil capacity is 7 quarts (6.6 liters) with the filter.
When to Change the Oil
The Grand Wagoneer has an automatic oil change indicator. When “Oil Change Required” appears, have the vehicle serviced within the next 500 miles (805 km). For the 6.4L, the manual also sets a hard limit: oil change intervals should never exceed 6,000 miles (10,000 km) or 6 months, whichever comes first. The engine controller also turns on the oil change indicator after 350 hours of engine run time.
