Why does the 1.5L Buick Excelle have high fuel consumption?

[DiMaddox]

Here are the reasons for the high fuel consumption of the 1.5L Buick Excelle: Clogged fuel system: Excessive carbon deposits causing fuel line blockage, leading to increased fuel consumption. Brake abnormalities: Brake pads not retracting properly, resulting in the vehicle constantly driving in a braking state. Spark plug malfunction: Generally, spark plugs need replacement after 20,000-30,000 kilometers. If you notice high fuel consumption, check if the spark plugs have abnormal ignition. Dirty air filter: Vehicle maintenance requires timely replacement of the air filter, otherwise it may cause poor air intake and increased fuel consumption.

My 1.5L Buick Excelle has been in use for five or six years, and I've encountered high fuel consumption issues multiple times, mainly due to poor driving habits and infrequent vehicle maintenance. Rapid acceleration and hard braking are very fuel-intensive, with fuel consumption spiking instantly every time I stomp on the gas pedal. Frequent starts in city traffic jams make it even worse, pushing average fuel consumption above 10L. A dirty air filter blocking air intake and worn-out spark plugs affecting ignition efficiency both lead to incomplete fuel combustion. Underinflated tires increase rolling resistance, and I found that for every 10kpa drop in pressure, fuel consumption rises by 5%. After correcting bad habits like adopting smoother driving techniques and braking in advance, along with regular air filter and spark plug replacements, fuel consumption dropped to 7-8L, saving me a lot on gas money. Excessive use of air conditioning in summer also increases fuel consumption, but controlling the temperature setting can help. As the vehicle ages, engine seal leaks might occur (though rare), so I recommend checking the engine oil condition every 5,000 kilometers.

As a regular driver of the Buick Excelle 1.5L for family use, I find the high fuel consumption is often due to urban road conditions and improper maintenance. In the city, frequent stops at red lights, constant acceleration from standstill, and low-speed driving waste fuel, so my car averaging 9-10L per 100km is no surprise. Fuel consumption increases further when the trunk is loaded with heavy items or when carrying more passengers. I didn’t pay attention to low tire pressure before, but after replacing the tires, the reduced rolling resistance made a noticeable difference. Replacing a clogged air filter showed immediate improvement, and cleaning carbon deposits from the spark plugs stabilized ignition. I also noticed that excessive use of air conditioning raises fuel consumption, so I recommend setting a moderate temperature to save fuel. Adjusting driving habits to avoid sudden braking and maintaining a steady speed even in city traffic helps too. Regular maintenance, such as changing engine oil to prevent wear, can reduce fuel consumption in the long run. In short, simple upkeep and habit adjustments can solve the issue—saving money and ensuring peace of mind.

When I first bought my 1.5L Excelle, the fuel consumption was shockingly high, and I initially thought it was due to the car being old. After inspection, I found that the spark plugs were worn out, causing poor ignition, which led to unburned fuel being expelled. The air filter was incredibly dirty; replacing it improved airflow and reduced fuel consumption. I also adjusted my driving habits: avoiding sudden acceleration, gently pressing the throttle, and anticipating stops in city driving to save fuel. The tire pressure was too low, increasing rolling resistance, but after inflating them properly, fuel efficiency improved. Not changing the engine oil for too long increased friction and fuel usage, but after regular oil changes, my fuel consumption stabilized at around 7.5L. Running the AC at full blast quickly raised fuel consumption, but now I adjust it moderately to save fuel.

High fuel consumption is thinning my wallet as a Buick Excelle 1.5L owner, mainly due to improper driving habits and vehicle condition management. Aggressive acceleration and sudden braking drastically increase fuel usage; underinflated tires significantly raise rolling resistance; a clogged air filter reduces combustion efficiency, wasting fuel. Recommendations include using apps to monitor real-time fuel consumption, maintaining an economical speed of 60-80km/h in urban areas for better mileage, clearing cabin clutter to reduce weight (avoid overloading the trunk), and using air conditioning wisely at 26°C in eco mode. For maintenance, upgrading to high-efficiency spark plugs and regularly cleaning the air filter are simple yet effective measures; frequent oil changes prevent engine strain. Slightly reducing speed during highway driving helps control fuel consumption. Implementing these strategies now saves me hundreds in monthly fuel costs - practical results.
