Can I Add Water to Windshield Washer Fluid?

Adding water to windshield washer fluid is not recommended. Windshield washer fluid, also known as car window cleaning solution, serves multiple purposes beyond just cleaning, including lubrication, antifreeze, anti-fogging, and anti-static properties. While adding water may partially achieve a cleaning effect, tap water often contains impurities that can corrode rubber hoses and clog nozzles over time. Currently, there are three types of windshield washer fluids available: one for summer use, which contains not only standard cleaning agents but also insect-removing compounds to quickly eliminate insect residues on the windshield; another for winter use, featuring antifreeze properties that allow it to function normally at temperatures as low as -20°C, preventing freezing and even melting ice and snow to some extent; and a third type designed for extremely cold regions, capable of remaining unfrozen even at -40°C.

Can I add engine oil right after stopping the car?

You can add engine oil right after stopping the car, but you need to pay attention to the amount added. Since the oil level differs between a cold engine and a hot engine, the oil level in a hot engine is usually slightly lower than in a cold one. Therefore, when adding oil to a hot engine, be cautious not to overfill it to avoid exceeding the upper limit on the dipstick when the engine cools down, which could lead to oil leaks. The optimal oil level should be slightly above the middle mark on the dipstick, and it can be a bit lower when the engine is hot. Here are some important points to note when adding engine oil: 1. For older cars, it is recommended to check the oil level every two months, while for new cars, every 3 to 4 months. If the oil level is found to be insufficient, it should be replenished promptly. Avoid mixing different brands or specifications of engine oil. 2. Regular inspection and maintenance of the engine oil, especially the oil level, are essential. Insufficient oil can affect the normal lubrication of the engine, increase wear, and negatively impact engine performance and lifespan.

What is the fuel consumption of the Jiangling Kaiyun 116 horsepower?

Jiangling Kaiyun 116 horsepower has a fuel consumption of 15L per 100 kilometers. The following are related introductions about fuel consumption: 1. Habits and road conditions: Fuel consumption is greatly influenced by driving habits and road conditions. Avoid heavy acceleration; gradual acceleration from a start is the most fuel-efficient. To save fuel, avoid pressing the accelerator pedal hard when starting, as heavy acceleration consumes 2 to 3 times more fuel than normal acceleration. 2. Braking: Maintaining a safe distance and avoiding frequent braking saves more fuel. If you don’t maintain a safe distance, you may need to brake frequently on the road. When braking, an automatic transmission vehicle will downshift, requiring the engine to pull the vehicle back up from a lower gear. Starting from a standstill or in a low gear requires the engine to consume more fuel.
