Does anyone know the best fuel to use for a 2018 Jeep Grand Cherokee? I’ve heard different opinions and just want to make sure I’m using what’s best for the engine’s longevity.

For a 2018 Jeep Grand Cherokee, the best fuel to use depends on the engine you have. If you're driving a model with the standard 3.6L V6 engine, regular unleaded gasoline with an octane rating of 87 is perfectly fine and recommended. However, if you have the 5.7L V8 engine, while it can run on regular fuel, using mid-grade (89 octane) is often suggested for better performance and longevity. If you’re lucky enough to have the high-performance SRT model with the 6.4L V8, premium unleaded gasoline (91 octane or higher) is recommended.
