What is the fuel consumption of the Buick Regal 2.5-V6?

[AliceDella]

The older generation Regal equipped with a 2.5L 152-horsepower V6 engine and a 4-speed automatic transmission has an average fuel consumption of 12.16 liters per 100 kilometers, with a range of 10.37~13.94 liters per 100 kilometers. Factors contributing to high fuel consumption: Low tire pressure: Check if the tire pressure is insufficient and if the tires are worn. Insufficient or low tire pressure increases friction between the tires and the ground, leading to greater resistance and higher fuel consumption. Severe tire wear can cause frequent slipping, which also increases fuel consumption. Poor fuel quality: Pay attention to the quality of gasoline when refueling and clean carbon deposits regularly. Low-quality gasoline can lead to increased carbon deposits, which roughen the intake pipe walls, affecting the intake efficiency and the quality of the air-fuel mixture, causing a sharp rise in fuel consumption. Therefore, fuel quality cannot be ignored, and cleaning carbon deposits every six months is essential.
