The Jeep Grand Cherokee Trackhawk shares the Hellcat 6.2L supercharged Hemi but adds 5,000+ pounds of mass, optional towing, and SUV heat management challenges. Oil breaks down under the same supercharged stress plus extra load from cargo, passengers, and trailer tongue weight.
Correct oil and interval discipline keeps the blower and bottom end healthy — especially when paired with brake and tire maintenance on a platform that stops as hard as it accelerates.

Use 0W-40 full synthetic (MS-6395), ~7 quarts with filter. Replace filter every change. Inspect for leaks around the oil cooler lines common on high-mile Trackhawks.

Short trips, idle-heavy traffic, track days, and max towing all qualify as severe duty. If you smell oil after hard runs or see pressure drops at hot idle, service immediately and inspect PCV/oil separator function.
