The original factory specification for the Great Wall Haval H2 is SL grade 10W-40 semi-synthetic engine oil. Any oil with the same specifications can be used. In addition to the original factory oil, you can also choose brands such as Shell, Mobil, and Castrol. If SAE-10W-30 or higher viscosity engine oil is used in cold weather, the engine may be difficult to start. Therefore, it is recommended to use SAE-0W-20, 5W-20, or 5W-30 engine oil in northern regions. Using 0W-20 oil can maximize fuel savings. More information about engine oil is as follows: 1. Engine oil refers to the lubricant specifically used in internal combustion engines. In addition to lubrication, it also has functions such as cleaning, rust prevention, and cooling. 2. If too much oil is added, it will increase the amount of oil splashed into the cylinder wall when the crankshaft and connecting rod rotate, increasing the rotational resistance of the crankshaft, reducing the engine's output power, and increasing fuel consumption. 3. It is advisable to keep the oil level slightly below the MAX mark on the dipstick. The engine oil dipstick has upper and lower limits, and the oil level should be between these two limits.

The Haval H2 generally recommends using 5W-30 viscosity engine oil, as it can adapt to various temperature conditions. It flows well in sub-zero temperatures, reducing cold-start wear, and maintains oil film stability in hot weather. Fully synthetic oil is the best choice due to its durability, with a service life of up to 10,000 kilometers per change. Synthetic oil also offers excellent cleaning properties, preventing engine carbon buildup and improving fuel efficiency. For harsh driving conditions, such as frequent long-distance travel, prioritize high-grade oil with API SN or higher ratings to ensure lubrication and protection. Don’t forget to check the user manual—manufacturer recommendations are the most reliable. Using the wrong oil may lead to increased fuel consumption or engine noise, so regular oil level checks are crucial.

How often should the Mondeo's battery be replaced?

The Mondeo's battery generally needs to be replaced every 3-4 years. The following situations indicate the need for battery replacement: 1. Voltage test: Normally, the no-load voltage of the battery is around 13V. If the no-load voltage is below 10V during testing, it means the battery needs replacement. Otherwise, the vehicle may experience difficulty starting or fail to start. 2. Visual inspection: Check if there is any bulging around the battery, similar to a swollen phone battery. This indicates the battery has reached the end of its lifespan and must be replaced. Additionally, look for white or green powder around the battery. These oxides mean the battery is no longer usable.

Is it allowed to overtake when passing through a traffic light?

After passing through a traffic light intersection, it is permissible to change lanes. If you have already crossed the solid line and entered the middle of the intersection, you can overtake the vehicle in front, but it is best to change lanes and overtake only when there is sufficient safe distance. In principle, as long as none of the following regulations are violated, it is not considered a traffic violation. The key points for overtaking timing are as follows: 1. Good road conditions: Overtake when the traffic and road conditions ahead of the vehicle in front are good. There should be no signs prohibiting overtaking ahead of the vehicle in front, no possibility of forcing the vehicle ahead to change direction to the left within the overtaking distance, and no obstacles that would hinder the normal driving of your vehicle on the left side of the road. 2. No impact on oncoming traffic: Overtake when oncoming traffic does not affect the overtaking. Before overtaking, ensure that the oncoming vehicles are far beyond the overtaking distance, so that when overtaking the vehicle in front, the oncoming traffic will not affect normal driving. 3. Lower speed of the vehicle in front: Overtake when the vehicle in front is traveling at a lower speed. The speed of the vehicle being overtaken should be slower than your vehicle's speed, allowing you to quickly overtake at a speed below the maximum limit.

What is the fuel consumption per 100 kilometers for the Touareg two-wheel drive luxury version?

The fuel consumption per 100 kilometers for the Touareg two-wheel drive luxury version is 7.4L, which is the official data. The fuel tank capacity of the Touareg two-wheel drive luxury version is 70L, and the distance it can travel on a full tank is 70/7.4*100=945km. The fuel consumption of a car is directly related to five major factors: driving habits, the car itself, road conditions, natural wind, and environmental temperature. The specific factors that can increase fuel consumption are as follows: Driving habits: Aggressive driving, such as sudden acceleration, frequent overtaking, and not easing off the throttle before encountering a red light, can increase fuel consumption. The car itself: Cars with larger engine displacements generally consume more fuel than those with smaller displacements because larger displacements usually mean higher power output, requiring more gasoline for combustion. Cars with greater weight also consume more fuel because heavier vehicles require more torque to drive. Road conditions: Driving on dirt roads, muddy roads, soft surfaces, or mountainous roads increases resistance and fuel consumption. Natural wind: Driving against the wind or on windy days increases the car's resistance and fuel consumption. Low environmental temperatures: When the engine block is cold, the injected gasoline does not atomize easily, requiring more gasoline for combustion, which increases fuel consumption. Additionally, at low temperatures, the engine's computer may control the engine to run at higher RPMs to warm up, which also increases fuel consumption.

What is the difference between international gear and sequential gear on motorcycles?

The difference between sequential gear and international gear is: the neutral position in international gear is located between first gear and second gear; in sequential gear, the neutral position can be directly accessed from the highest gear. Below are the relevant introductions: 1. Sequential gear: Motorcycles with sequential gear are driven by gasoline engines, equipped with internal combustion engines, and steered by handlebars for front wheel control. They are widely used for patrol or passenger and cargo transportation, and can be specifically categorized into street bikes, road racing motorcycles, off-road motorcycles, cruisers, and touring bikes, which can also be used for military and sports competitions. 2. International gear: Motorcycles consist of five main parts: the engine, transmission system, running gear, steering, braking system, and electrical instrumentation equipment. The transmission system includes primary reduction, clutch, gearbox, and secondary reduction.
