Does Faster Speed Save More Fuel?
1 Answers
Driving at higher speeds does not save more fuel. Regular maintenance can reduce fuel consumption: Regular maintenance can decrease the vehicle's failure rate 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 usage. Avoid heavy acceleration: Heavy acceleration only shortens driving time by about 4%, but increases fuel consumption by 37-40%. On typical urban roads, the speed usually stays around 50 km/h, with engine RPM between 2000-2500. On highways, speeds generally range from 90-110 km/h. For every 10 km/h increase in speed, fuel consumption rises by 10%. Avoid heavy acceleration because RPM is the most significant factor affecting fuel consumption.
