GL8 actual fuel consumption is 7.8 to 7.9L/100km. Reasons for increased fuel consumption: Displacement, the engine displacement has a certain impact on the car's fuel consumption, but this impact is a fixed value. Tire pressure, the car's fuel consumption is also directly related to tire pressure. When the tire pressure is too high or too low, the car's fuel consumption will increase. Road conditions, the driving conditions of the car will also affect fuel consumption. Methods to reduce fuel consumption: When starting, do not accelerate sharply, shift at low RPMs, do not compete with others at red lights, treat any dents on the car body, close the windows at high speeds to avoid increased resistance, coast in high gear, never coast in neutral as it can easily lead to steering and brake failure.

As a long-time Buick GL8 owner, I've driven this car for four years and feel fuel consumption really depends on your driving habits. In urban commuting with heavy traffic, it can reach 12 liters per 100 km, even spiking to 14 liters during rush hour congestion. On highways though, it's quite fuel-efficient - maintaining around 90 km/h brings consumption down to just over 8 liters. My personal strategy involves minimizing sudden acceleration and maximizing coasting, which has saved me significant fuel costs over the year. I also maintain tire pressure at 2.5 bar to avoid unnecessary fuel waste. The spacious interior is a major advantage, especially for family outings with kids, though you have to acknowledge its substantial weight. Overall, the combined fuel consumption averages about 11 liters - not outrageous but certainly not as low as compact sedans, so potential buyers should factor fuel costs into their budget.

How to Adjust Large Headlight Gaps?

The gaps of car headlights can be adjusted. The mounting holes of the headlights are mostly elongated holes, allowing for fine-tuning. However, if the gap is too large or the car has been in an accident, relying solely on the mounting holes may not achieve the desired state.

What to Do When the Sunroof Seal Ages?

Slowly pull out the old sunroof seal along its track and thoroughly clean the gaps inside. Force the new seal directly into place along the sunroof track. Carefully check if there are any protruding parts of the seal. If there are, it means the seal is not fully installed, and you need to apply more force to push the protruding part in.

How to Keep the Steering Wheel Steady When Shifting Gears?

When holding the steering wheel, gently rest your thumbs on the inner side of the wheel and let your other fingers naturally hang down. Avoid inserting any fingers into the steering wheel, and maintain a light grip. You can practice with an actual car or a simulator. Once you are familiar with gear operations, it will take less time, and briefly removing your right hand from the steering wheel won't cause panic.
