Why Do New Cars Consume More Fuel?

[LucyLynn]

New cars have higher fuel consumption due to reasons such as insufficient break-in, poor fuel system flow, and excessive vehicle load. During the break-in period, the friction resistance of new components is relatively high, leading to increased fuel consumption. Insufficient Break-in: For a newly purchased car, the engine components have not yet fully broken in, resulting in smaller gaps between parts and greater operational resistance compared to a broken-in engine. Therefore, it's advisable to patiently complete the break-in period and observe if fuel consumption changes after the first maintenance. If fuel consumption remains higher post-break-in, it may indicate dirty fuel injectors or throttle body that require cleaning. Poor Fuel System Flow: Excessive engine carbon buildup is the primary cause of poor fuel system flow, often resulting from using inappropriate fuel in the short term. Excessive Vehicle Load: Avoid driving with excessive weight during the break-in period. A lighter load is better for new cars as heavy loads can cause damage.
