Does Higher Speed Mean Better Fuel Efficiency?

[StDaniella]

Higher speed does not mean better fuel efficiency. Regular maintenance can reduce fuel consumption: Regular maintenance can reduce the failure rate of the car and also lower fuel consumption. Scheduled replacement of parts such as spark plugs, oil filters, brake fluid, radiator coolant, air filters, power steering fluid, and transmission fluid ensures the vehicle remains in optimal condition, thereby reducing fuel consumption. Avoid heavy acceleration: Heavy acceleration only shortens driving time by 4%, but increases fuel consumption by 37-40%. On typical urban roads, the speed is usually maintained at 50 km/h, with the engine speed around 2000-2500 rpm. On highways, speeds generally range from 90-110 km/h. For every 10 km/h increase in speed, fuel consumption increases by 10%. Avoid heavy acceleration, as engine speed is the biggest factor affecting fuel consumption.
