For your 2019 Jeep Cherokee, the type of gasoline you should select depends on your engine type. If you have a 2.0 L engine, it is best to use premium unleaded gasoline with an octane rating of 91 for optimal performance, though regular unleaded is also acceptable. For the 2.4 L and 3.2 L engines, it is recommended to use regular unleaded gasoline with an octane rating of 87. To ensure smooth operation and avoid potential issues, it's advisable to always keep your vehicle adequately fueled to prevent getting stranded on the road. Running on low gas for an extended period can even lead to a shorter lifespan for your fuel pump.
How can I determine the size of my car's engine?
The 2019 Jeep Cherokee, equipped with a front-wheel drive 3.2L V6 engine, suggests using 89 octane unleaded gasoline, while other engine choices can run smoothly on 87 octane regular unleaded fuel.
The manual recommends using regular gasoline, as using a higher octane could not only be unnecessary but may also harm an engine with low compression.
