Main Menu Table Of Contents Break-in Period, Fuel Recommendation Break-in Period Help assure your vehicle'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 for the first 200 miles (300 km). Do not change the oil until the multi-information display indicates it is needed. Do not tow a trailer. ● ● Fuel Recommendation Your vehicle is designed to operate on premium unleaded gasoline with a pump octane of 91 or higher. If this octane grade is unavailable, regular unleaded gasoline with a pump octane of 87 or higher may be used temporarily. The use of regular unleaded gasoline can cause metallic knocking noises in the engine and will result in decreased engine performance. The long-term use of regular-grade gasoline can lead to engine damage. We recommend quality gasolines containing detergent additives that help prevent fuel system and engine deposits. In addition, in order to maintain good performance, fuel economy, and emissions control, we strongly recommend, in areas where it is available, the use of gasoline that does NOT contain manganese-based fuel additives such as MMT. Use of gasoline with these additives may adversely affect performance, and cause the malfunction indicator lamp on your instrument panel to come on. If this happens, contact your dealer for service. Some gasoline today is blended with oxygenates such as ethanol or MTBE. Your vehicle is designed to operate on oxygenated gasoline containing up to 10% ethanol by volume and up to 15% MTBE by volume. Do not use gasoline containing methanol. If you notice any undesirable operating symptoms, try another service station or switch to another brand of gasoline. For further important fuel-related information, please refer to your Quick Start Guide. ● You should also follow these recommendations with an overhauled or exchanged engine, or when the brakes are replaced. 322 2009 MDX
