What kind of gas does a 2018 Jeep Grand Cherokee take?

The 2018 Jeep Grand Cherokee is specified by the factory specs to use regular unleaded 87 octane gasoline or higher in the 3.6L non SRT Jeep and the SRT 6.2L and 5.7L use 89 octane plus unleaded. The fuel tank size for the car is 24.6 gallons and will give You about 550 to 600 miles for a full tank. The gas mileage is great and You can expect to get 21 MPG combined city and highway. Despite popular belief the higher the octane fuel does not have any real benefits for Your engine or vehicle. It has been said You will get better gas mileage or it can potentially keep Your fuel injectors and fuel pump cleaner but these statements have been found to be false. The only vehicles that do require higher octane are luxury or performance vehicles that have a turbo or engine that requires higher combustion rates such as the SRT trim levels.
