At What Engine RPM is Fuel Most Efficient?

[LeoLynn]

Generally, for fuel-injected vehicles, maintaining an engine RPM between 2200-2500 while driving is considered most fuel-efficient. Below are some methods to save fuel: 1. Regularly check the tire system: Insufficient tire pressure increases friction between the tires and the ground, leading to higher fuel consumption. Therefore, it's essential to frequently check tire pressure, as different vehicle models and tires have varying standard pressure levels. Additionally, severely worn tires can cause slippage and increase fuel consumption, necessitating replacement when needed. 2. Regularly inspect the braking system: Some vehicles may experience slight brake drag, effectively increasing the vehicle's load during driving and raising fuel consumption, so periodic checks are crucial. 3. Perform regular maintenance and replace parts: Air filters, gasoline filters, and oil filters need replacement every 5,000 kilometers or more, as a clogged air filter reduces air intake, leading to incomplete gasoline combustion and decreased fuel efficiency. Wear on the clutch plate and clutch pressure plate, as well as prolonged use of spark plugs, can also result in increased fuel consumption, so these should be replaced periodically.
