Review the utility and maintenance guidelines below, or visit Johnsons of Kingfisher for certified Jeep service.
Hurricane Twin-Turbo Towing Capacity
The 2026 Grand Wagoneer is engineered to deliver uncompromising power without sacrificing refined luxury. The standard 3.0-liter Hurricane Twin-Turbo Inline-6 engine provides breathtaking acceleration while delivering a best-in-class maximum towing capacity of up to 10,000 pounds.
This immense towing strength makes the Grand Wagoneer the ultimate vehicle for pulling massive boat trailers, multi-horse trailers, or large luxury campers across Kingfisher County. Backed by standard Trailer Sway Control, available load-leveling Quadra-Lift air suspension, and the legendary Quadra-Drive II 4x4 system, you can haul the heaviest loads with absolute confidence and stability. To explore the luxury technology features inside the cabin that accompany this power, visit our dedicated Jeep Grand Wagoneer Research Hub.
Hurricane Engine Oil Capacity and Maintenance
To ensure your Hurricane Twin-Turbo engine maintains its 10,000-pound towing capability and lightning-fast throttle response, adhering to strict fluid requirements is critical. The 3.0-liter twin-turbo engine requires 7.5 quarts of full synthetic motor oil. Because the twin turbochargers generate extreme internal heat, synthetic oil is absolutely required to protect the high-speed bearings and prevent oil breakdown during heavy towing in the Oklahoma summer heat.
We highly recommend bringing your Grand Wagoneer to our CDJR Service Center near Kingfisher when your oil life indicator illuminates. Our factory-trained Mopar technicians will ensure the exact synthetic oil weight (0W-20 for Standard Output or 0W-40 for High Output models) and genuine OEM filters are utilized every time.
