How to Calculate Tire Aspect Ratio?

Does Refueling in Summer Cost Less Than in Winter?

Refueling in summer costs less than in winter. Here are some explanations about refueling in summer and winter: 1. Reasons for consuming more fuel in winter: Cold starts consume more fuel. During winter, the coolant temperature is much lower than in summer. During the time it takes for the engine to reach normal operating temperature, the coolant absorbs more energy, requiring more fuel to compensate. Prolonged warm-up times also contribute to higher fuel consumption, as fuel efficiency during warm-up is much lower than during normal driving. This is one reason for increased fuel consumption, and incorrect warm-up methods can further exacerbate the issue. 2. Factors that increase fuel consumption: Poor tire maintenance can lead to higher fuel consumption. Wider tires have a larger contact area with the road, increasing friction and resistance. Severely worn tires may also cause more slippage, indirectly increasing friction and resistance, leading to higher fuel consumption.

How to Handle Hydroplaning in a Vehicle?

Hydroplaning is prone to occur when driving in rainy weather. Below is a detailed introduction to handling methods: 1. Steady the steering wheel: Typically, when a front-wheel-drive vehicle hydroplanes, due to the heavier front body, the rear wheels hydroplane first. At this time, the vehicle's tracking is still acceptable. As long as you hold the steering wheel firmly and wait for the speed to decrease until traction is regained, you can escape the danger. 2. Ease off the accelerator and gradually decelerate: When driving at high speed in the rain, do not brake harshly. In fact, abruptly releasing the accelerator is also not advisable, as its effect is equivalent to harsh braking. When the vehicle speed (tire rolling speed) exceeds this critical speed, the tire's drainage function cannot meet the demand, and hydroplaning will occur. Moreover, the higher the vehicle speed (tire rolling speed), the more likely hydroplaning is to occur.

Is it okay to occasionally use 92 octane gasoline?

Occasional use will not have any significant impact on the vehicle. If a car that should use 95 octane gasoline is filled with 92 octane, knocking may occur during operation. The engine can tolerate minor knocking, but prolonged use of lower-octane fuel with frequent knocking can damage the engine and increase carbon deposits, placing a greater burden on the engine. Below are some additional tips for refueling: 1. Refuel when there's one bar left on the fuel gauge: You should refuel when the gauge shows one bar remaining, rather than waiting for the fuel light to come on. The fuel light indicates that the fuel level is already below the fuel pump, and refueling at this point can shorten the pump's lifespan. Too little fuel or running out completely may even burn out the fuel pump. 2. Don't overfill the tank: Filling the tank to the brim displaces air, allowing more fuel than the rated capacity to be added, which can also pose safety hazards. Filling only to the rated capacity meets safety requirements and reduces the vehicle's load.

Is a tire pressure of 2.2 a bit low in summer?

In summer, a tire pressure of 2.2 is not considered low, as maintaining tire pressure at 2.2 during the summer season falls within the normal range. Here is some relevant information about car tire pressure: 1. Impact of car tire pressure: During summer driving, it is necessary to regularly monitor the tire pressure of the vehicle. If the tire pressure is too low, it can lead to excessive tire wear. Conversely, if the tire pressure is too high, there is an increased risk of tire blowouts while driving. 2. Solutions for insufficient car tire pressure: If the tire pressure is low, you can go to a local repair shop to refill the tire pressure. If you are on the road, slow down and find a nearby repair facility. If the tire pressure drops to a certain level, it is advisable to replace it with the spare tire first. Generally, spare tires are non-full-size, so after replacing with the spare tire, it is important to control the vehicle speed and avoid driving too fast.

Are Buick Cars High in Fuel Consumption?

Buick cars tend to have slightly higher fuel consumption compared to other Japanese and German models in the same class. However, when compared to its American counterparts like Ford and Chevrolet, Buick cars perform much better in terms of fuel efficiency. In reality, vehicle fuel consumption cannot be judged solely by engine parameters. Other factors such as transmission, aerodynamic drag, tires, vehicle weight, and driving habits also significantly impact fuel consumption. Relevant information on Buick cars' fuel consumption: 1. Driving Habits: Fuel efficiency is greatly influenced by driving habits. Aggressive acceleration can make even a small car like the QQ consume more fuel. On the other hand, maintaining reasonable RPM and speed under suitable road conditions can lead to better fuel efficiency, known as constant-speed fuel consumption. Not all Buick cars are fuel-guzzlers; driving habits play a crucial role in determining fuel consumption. 2. Engine Fuel Control: Buick's latest ECOTEC engine, which is part of Buick's global strategy, represents a significant improvement over previous models. It features variable valve timing, which greatly aids in controlling fuel consumption.

What does BMW 5 Series G38 mean?

G38 is an internal code name for the BMW 5 Series, specifically the domestically produced long-wheelbase version. Most BMW 5 Series owners in China are from the post-80s generation. The BMW 5 Series combines both sporty and luxurious attributes, which aligns well with the consumption demands of this age group. Below are the relevant details: 1. Differences: The previous generation 5 Series and 7 Series maintained a high degree of consistency in body structure, with the F10 5 Series and F01 7 Series sharing most body structural components, resulting in differences mainly in size variations. In the current new generation 5 Series G30 (standard wheelbase version) and 7 Series G11, BMW has introduced dedicated designs for these two differently positioned products to justify the luxury and performance of the 7 Series, thereby amplifying the differences between the two models. 2. Engine: The domestic long-wheelbase BMW 5 Series offers a choice between the 2.0T four-cylinder B48 engine and the 3.0T six-cylinder B58 engine, consistent with the overseas versions. Both are produced using BMW's modular platform, sharing most parts and technologies.
