To open Your 2015 Jeep Grand Cherokee vehicle's gas tank, locate the release button for the fuel door on the driver's side of the vehicle and release. Unscrew the gas cap in a counter-clockwise motion. Once Your gas cap is removed You will then select the type of gas from the fuel pump. RegulaR87 octane gas or higher can be used. In most cases, using a higher octane gasoline than Your owner's manual recommends offers absolutely no benefit. It won't make Your car perform better, go faster, get better mileage, or run cleaner.How You drive can significantly affect Your fuel economy. The harder You accelerate, the more fuel You use. Unnecessary braking wastes the fuel You used to get up to speed.

Except (referring to answer #1) there is no gas cap to unscrew. You simply insert the gas nozzle passed the flap located under the entry hatch and fill the tank. The flap operates in such a manner that a gas cap is not necessary.
