3.0L GL8 fuel consumption per 100 kilometers: 6.5-6.6L. Here are some methods to reduce fuel consumption: 1. Check the air conditioning system in summer: Air conditioning malfunctions are a significant cause of high fuel consumption. Poor cooling performance will require higher fan speeds and lower temperatures to achieve a comfortable effect. 2. Frequent hard braking: Frequent hard braking is a major reason for high fuel consumption. While ensuring safe driving, make full use of the vehicle's inertia. 3. Avoid excessive air conditioning in small-displacement vehicles: For vehicles exposed to the sun, do not turn on the air conditioning immediately after entering. First, open the windows and set the fan to a higher speed without turning on the air conditioning to expel the hot air inside. Wait until the vehicle has cooled down moderately before turning on the air conditioning.

I understand the fuel consumption issue of the Buick GL8 with a 3.0L displacement. Under typical city driving conditions, the fuel consumption ranges from 10-12 liters per 100 kilometers, while highway driving is more economical, averaging around 8-10 liters. The combined average is approximately 10-11 liters. This data is based on my actual driving experience, and higher fuel consumption is common given that the GL8 is a large MPV with significant body weight, naturally consuming more fuel. Your driving habits also have a notable impact—rapid acceleration or frequent braking can increase fuel usage. I recommend maintaining tire pressure within the recommended range, such as the manufacturer-suggested 32-35 psi, which can help reduce fuel consumption. The air conditioning is another major fuel consumer; running it at full blast in summer can increase fuel consumption by about 1 liter. Considering fluctuating fuel prices, you might spend a few hundred yuan more on fuel each month, but the GL8’s spaciousness and comfort are its advantages. Overall, the fuel consumption is moderate—it’s not the best choice for daily commuting but is well-suited for family trips.

Our family has been using the Buick GL8 3.0 to shuttle the kids to school and for long-distance trips, with an average fuel consumption of about 11 liters per 100 kilometers. During heavy traffic in the city during morning and evening rush hours, it easily exceeds 12 liters. On highways, when I drive at speeds of 90-100 km/h, it drops to around 8 liters, which is quite fuel-efficient. Monthly fuel expenses are close to 1,500 yuan, and when the fuel price reaches 8 yuan per liter, we have to budget carefully. Proper maintenance can help, such as regularly changing the air filter to keep the engine running more efficiently. I service it once a year, which helps stabilize fuel consumption. Carrying large or heavy luggage can also slightly increase fuel consumption, so it's better to avoid overly heavy items. This MPV has ample power but relatively high fuel consumption, yet its spacious, practical, and safe seats make it ideal for families with kids.

I find the fuel consumption of the GL8 3.0 to be high. A combined 11 liters per 100 km is normal, and it may exceed 12 liters in city traffic jams. Maintaining a steady speed of 80-100 km/h on the highway can reduce it to 8 liters. Lightly pressing the accelerator and braking less significantly saves fuel. Keeping tire pressure at the recommended 32 psi without underinflation is more economical. Using cruise control in eco mode on the highway works well, and setting the air conditioning to a moderate temperature consumes less fuel. It's advisable to use energy-saving tires, regularly clean carbon deposits, and replace aging spark plugs promptly. In the long run, high fuel consumption imposes a greater environmental burden, so switching to an electric or hybrid vehicle is a greener option.
