What kind of gas does a Jeep Cherokee use?

The type of gas a Jeep Cherokee uses depends on the year and model. Most modern Jeep Cherokees (generally from the late 1990s onward) use regular unleaded gasoline (87 octane). However, some models and trims might recommend or perform slightly better with mid-grade (89 octane) or even premium (91+ octane) fuel. Always check the owner's manual for the specific fuel recommendation for your particular Jeep Cherokee.
