I've been driving a Hummer H3 for five years, and this car is indeed a gas guzzler. In city traffic jams, it consumes around 20 liters per 100 kilometers, while highway cruising can drop it to about 15 liters. It mainly depends on how you drive—aggressive acceleration and braking can easily push it to 22 liters. With a 3.7-liter engine paired with a 2-ton body, it guzzles fuel even when starting from traffic lights. Once, a friend took the same model off-roading, and the fuel gauge visibly dropped while climbing hills, reaching up to 25 liters on dirt roads. With fuel prices so high now, you'd better budget an extra 2,000 yuan per month for gas if you drive this car. Modifications like spare tires or extra roof racks will make it even thirstier.

Do You Need to Idle When Driving Through Water?

Do You Need to Idle When Driving Through Water. Source: During the rainy season and typhoon season, road flooding or waterlogging often occurs, especially in low-lying areas and underground passages, which are quite common. Therefore, extra caution is required when driving through these areas, as negligence may lead to severe engine damage. Location: In most vehicles, the engine air intake is positioned above or in the center of the front bumper. If the water level approaches the bumper, water can easily be sucked into the engine, causing damage. Since water cannot be compressed, its entry into the cylinders creates excessive pressure, which can bend or even break the connecting rods and crack the engine block.

Which way to steer when the left side is too wide during reverse parking?

If the left side is too wide during reverse parking, turn the steering wheel to the left. Here are the correct methods for dealing with a wide left side: 1. The simplest method is to observe through the left rearview mirror. Turn the steering wheel towards the side that is wider, so in this case, turn it to the left. 2. If the speed is not well controlled during reverse parking, it is already half a failure. During regular practice, it is essential to learn the correct way to press the clutch. Place the ball of your foot on the clutch pedal with your heel on the ground as a support point. When the clutch is pressed to the lowest point, keep your knee slightly bent to maintain an appropriate speed.
