Break-in Period, Gasoline Break-in Period Help assure your car's future reliability and performance by paying extra attention to how you drive during the first 600 miles (1,000 km). During this period: Avoid full-throttle starts and rapid acceleration. Avoid hard braking. New brakes need to be broken-in by moderate use for the first 200 miles (300 km). You should follow these same recommendations with an overhauled or exchanged engine, or when the brakes are relined. Gasoline Your Honda is designed to operate on unleaded gasoline with a pump octane number of 86 or higher. Use of a lower octane gasoline can cause a persistent, heavy metallic rapping noise in the engine that can lead to mechanical damage. We recommend gasolines containing detergent additives that help prevent fuel system and engine deposits. Using gasoline containing lead will damage your car's emission controls. This contributes to air pollution. In Canada, some gasolines contain an octane-enhancing additive called MMT. If you use such gasolines, your emission control system performance may deteriorate and the Malfunction Indicator Lamp on your instrument panel may turn on. If this happens, contact your authorized Honda dealer for service. Oxygenated Fuels Some conventional gasolines are being blended with alcohol or an ether compound. These gasolines are collectively referred to as oxygenated fuels. To meet clean air standards, some areas of the United States and Canada use oxygenated fuels to help reduce emissions. If you use an oxygenated fuel, be sure it is unleaded and meets the minimum octane rating requirement. Before using an oxygenated fuel, try to confirm the fuel's contents. Some states/provinces require this information to be posted on the pump. Before Driving
