Why does the Civic consume 10 liters of fuel per 100 km?

Possible reasons for the Civic consuming 10 liters of fuel per 100 km are as follows: 1. Insufficient tire pressure: If you suddenly notice increased fuel consumption in your car, the first thing to check is the tires. Verify whether the tire pressure meets the standard and if there is any tire wear. Both insufficient tire pressure and tire wear can increase rolling resistance. 2. Frequent braking and acceleration: Apart from factors like vehicle design and engine performance, the primary cause of excessive fuel consumption is the driver's habits. Frequent hard braking and rapid acceleration are the biggest contributors to increased fuel consumption. 3. High speed in low gear: One of the biggest driving misconceptions is driving at high speeds in low gears. For instance, driving long distances at high speed in 3rd gear can increase fuel consumption by 10% compared to normal driving in 4th gear. Using 2nd gear instead of 3rd gear will further increase fuel consumption. Therefore, selecting the appropriate gear based on speed is crucial for fuel efficiency.
As a long-time Civic driver, I've found that 10L/100km fuel consumption is often due to poor driving habits. Many people press the accelerator too hard, with sudden acceleration and braking, leaving the engine no time to operate efficiently, thus burning more fuel. Frequent urban traffic jams and stop-start at traffic lights naturally push consumption to 10L. Heavy AC usage, especially in summer, adds significant extra load. Automatic transmission versions experience delayed gear shifts at low speeds, consuming more fuel. I recommend gentle acceleration, maintaining steady speeds, reducing AC reliance, and regular highway driving to clear carbon deposits. Also, check tire pressure - underinflated tires increase rolling resistance, wasting dozens of kilometers per liter. These small adjustments can restore normal consumption levels. The Civic should average around 7L/100km - driving style makes a huge difference. Don't assume mechanical issues when it's just your driving technique.
From a maintenance perspective, the Civic's fuel consumption of 10 liters often stems from neglect in upkeep. Insufficient tire pressure increases friction, leading to 1-2 liters more fuel consumption. A clogged air filter prevents the engine from getting enough air, causing incomplete combustion and wasted fuel. Worn-out spark plugs with inaccurate ignition or a faulty oxygen sensor can disrupt the engine control unit's fuel management, making 10 liters the norm. Old engine oil with poor lubrication forces the engine to work harder, increasing fuel consumption. It's recommended to change to high-quality oil and filters on time, inspect the ignition coils, and clean carbon buildup from the throttle body. Aftermarket parts like exhaust kits can also interfere with aerodynamics, increasing fuel consumption. In short, simple maintenance can bring fuel consumption back down to 6-7 liters. The Civic is a fuel-efficient car—don't underestimate small components. Investing in a check-up at the dealership is worth it.
