Does Higher RPM Always Mean Higher Fuel Consumption?

[DeEmery]

Higher engine RPM does not necessarily mean higher fuel consumption. Factors affecting fuel consumption: Driver's habits, road conditions, vehicle load, use of air conditioning, and whether the vehicle is in the break-in period all influence fuel consumption. Every engine has an economical speed range. Maintaining this range during daily driving ensures both good power performance and optimal fuel combustion efficiency. Ways to reduce fuel consumption: Avoid prolonged idling or low-speed driving; avoid excessive vehicle load and full fuel tank; avoid using high-viscosity engine oil; try to control speed with the accelerator rather than the brake.
