Why is the Premacy's fuel consumption so high?

[StChloe]

Premacy's high fuel consumption may be due to a dirty air filter, excessive carbon buildup on the fuel injectors and throttle body, or poor-quality gasoline. Dirty air filter: Replace the air filter. If it wasn't changed during the 10,000 km maintenance, be sure to replace it at the 20,000 km maintenance. The air filter's function is to block dust particles from entering the engine during the intake process. If it was replaced at 10,000 km, it can be cleaned. Solutions for Premacy's high fuel consumption: Check if the air cleaner is unobstructed. Inspect the ignition timing and check for any fuel leaks in the pipelines. If none of the above issues are found, check whether black smoke is coming from the exhaust pipe after starting the car. Black smoke indicates incomplete combustion; if the air intake is fine, it means too much fuel is being injected. Also, listen for any backfiring or popping sounds, similar to firecrackers sometimes.

I drove a Premacy for several years and found its fuel consumption was indeed on the high side, especially in the city. The Premacy's engine is around 1.6 liters, and it often idles in urban traffic, burning more fuel while stationary. Plus, the car itself is quite heavy with significant aerodynamic drag, so fuel consumption spikes in areas with many traffic lights. Driving habits matter a lot—I used to accelerate and brake aggressively, which pushed fuel consumption above 11 liters per 100 km. Maintenance is also crucial; a dirty air filter or worn-out spark plugs can strain the engine and increase fuel consumption. I recommend regular maintenance, replacing worn parts, driving smoothly, and avoiding overloading. Paying attention to small details, like checking if tire pressure is too low (which increases friction), can also help reduce fuel consumption.

My Premacy's fuel consumption is shockingly high, averaging 11 to 12 liters per 100km. The car's outdated engine design leads to low efficiency in city driving; my aggressive driving style with frequent hard acceleration and sudden braking puts excessive load on the engine. Additionally, I've neglected maintenance - the air filter is clogged and unreplaced, and the spark plugs are worn out without inspection. I've heard the Premacy's tall body creates significant wind resistance, performing slightly better on highways, but my usual family trips with heavy loads consume even more fuel. Using AC in summer is disastrous, further increasing consumption. I need to change my driving habits, learning gradual acceleration and traffic anticipation, while sticking to regular maintenance schedules for filter replacements and electrical checks.

Factors contributing to the high fuel consumption of the Premacy include: the engine's inefficiency at medium to low RPMs, inflexible transmission matching leading to frequent RPM changes and increased fuel usage; insufficient tire pressure increases friction and fuel consumption; clogged air filters or carbon buildup in the fuel system make the engine work harder. I've noticed from data that fuel consumption during highway cruising is acceptable, but frequent starts and stops on city roads lead to significant wastage. It's recommended to regularly clean engine carbon deposits, replace spark plugs and air filters; maintain steady speeds while driving to avoid sudden changes. As the vehicle ages, component wear can exacerbate the issue, necessitating early maintenance to control fuel consumption levels.
