I just bought a Jeep Grand Cherokee. I want to treat my ride with as much care as possible, which includes giving it the right kind of gas. What type of gas does a Jeep Grand Cherokee need?
Grand Cherokee’s owner’s manual here are the recommendations you’d find:
For 2.0L and 3.6L engines: Use regular unleaded gasoline with an octane rating of 87 or higher.
For 5.7L engines: Unleaded gasoline with an octane rating of 87 to 89 is recommended.
Jeep Grand Cherokees and flex fuels don’t mix: On all these engine types, you should avoid using E-85 flex fuels or fuel blends that contain more than 15% ethanol, as you could risk damaging fuel system components—and it could even void your warranty.
Again, since fuel specifications can vary slightly depending on your model year and engine type, you’ll want to confirm your Jeep Grand Cherokee’s fuel requirements—including what fuel types to avoid—in your owner’s manual.
