★ Top Answer
The 2018 Jeep Grand Cherokee is built to run on regular unleaded 87 octane gasoline or better for the 3.6L non SRT model, while the SRT 6.2L and 5.7L models need 89 octane or higher. With a fuel tank capacity of 24.6 gallons, you can travel around 550 to 600 miles on a full tank. The car delivers an impressive gas mileage of 21 MPG combined for city and highway driving. Contrary to common belief, using higher octane fuel does not offer significant benefits for your engine or vehicle. Claims about improved gas mileage or cleaner fuel injectors and pump with higher octane have proven to be untrue. The only vehicles that necessitate higher octane are luxury or high-performance models with turbo engines that demand greater combustion rates, such as the SRT trim levels.
