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 1,000 km (600 miles). During this period: Avoid full-throttle starts and rapid acceleration. If you need to add oil, use the engine oil recommended in this owner's manual. Avoid hard braking. New brakes need to be broken-in by moderate use for the first 300 km (200 miles). 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 most effectively on unleaded gasoline. 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 and can void certain parts of your warranty. (S model) (All other models) Use a premium unleaded gasoline with a pump octane number of 91 or higher. If you are unable to find premium unleaded, you may substitute an unleaded regular gasoline. The engine will compensate for the lower octane, but you may notice a slight decrease in power as a result. Oxygenated Fuels Use an 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. 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 Driving
