Which gasoline grade is best for a Tahoe?

The best gasoline grade for a Chevrolet Tahoe typically depends on the engine model. For most standard models, regular unleaded gasoline with an octane rating of 87 is recommended. However, if your Tahoe has a high-performance engine, such as the V8 in the RST or Premier trims, premium gasoline with an octane rating of 91 or higher may be suggested for optimal performance. Always check the owner’s manual for specific recommendations based on your vehicle's engine type.
