Why has my car’s fuel consumption increased significantly?

Many people have noticed that their vehicles—once known for relatively low fuel consumption—suddenly start consuming much more fuel as they drive them. So today, let’s join Qingjie to find out exactly what’s behind this phenomenon! Poor driving habits can significantly increase fuel consumption—for instance, frequent rapid acceleration and braking, as well as constant starting and stopping. Therefore, adopting good driving habits is a crucial factor in keeping fuel consumption under control. Additionally, if a vehicle carries excessively heavy loads, its fuel efficiency will also suffer. Thus, it’s best to minimize the load as much as possible. Insufficient tire pressure: When tire pressure is too low, the contact area between the tires and the road surface increases, leading to excessive friction and greater resistance, which in turn boosts fuel consumption. Moreover, car enthusiasts should also...

Struggling to decide which motor oil to choose? Understand these points, and you’ll never waste money again!

Today, let’s talk about how to choose the right motor oil! Changing your engine oil is probably the most frequent maintenance task for a car. But which type of motor oil is best suited for you? Keep reading—currently, all the motor oils that car owners see are produced by adding additives to base oils. Depending on the grade of the base oil and the specific additives used, motor oils are categorized into three types: mineral oil, semi-synthetic oil, and fully synthetic oil. So, what exactly is mineral oil? Mineral oil has the lowest base oil grade; it’s made from crude oil distillates serving as its base oil. Its biggest advantage is that it’s inexpensive, but its performance is generally average. Therefore, although it can meet the minimum requirements of our engines, its degradation rate is relatively fast.

How can I tell if it’s antifreeze? That’s all I can help you with.

One type is counterfeit antifreeze made by diluting it with low-boiling-point alcohols such as methanol. This kind of counterfeit antifreeze has a very low boiling point—around 70°C to 80°C—which makes it highly volatile and prone to boiling, causing the radiator to overheat (the "water tank to boil"). Moreover, the evaporating fumes can severely damage human eyes. Once you’ve purchased this counterfeit antifreeze, even if you’re certain there are no leaks in the radiator hoses, you’ll find that it evaporates so rapidly that you’ll have to top it up frequently. It may also cause the radiator to boil regularly, thereby inflicting significant damage to the engine. In contrast, genuine antifreeze, provided there are no leaks in the radiator hoses, generally doesn’t require frequent topping up. That’s because the boiling point of genuine antifreeze is above 107°C—higher than the boiling point of water—and thus it rarely boils under normal operating conditions.

Drinking substandard antifreeze indiscriminately is simply ruining your car!

When it comes to car maintenance, most people tend to focus on consumables such as engine oil, spark plugs, and tires—yet few pay sufficient attention to antifreeze. Proper, high-quality antifreeze boasts functions including corrosion prevention, rust inhibition, scale prevention, and boil-over protection. By contrast, substandard antifreeze is typically made from industrial methanol, recycled ethylene glycol, low-grade ethylene glycol, and even diluted with tap water. Such antifreeze is prone to producing impurities and inorganic salts, and it’s highly corrosive. This can lead to corrosion of the vehicle’s cooling system, loosening of the water pump impeller, and ultimately, complete failure of the cooling system, rendering it unable to function properly and causing severe damage to the engine. However, the quality of antifreeze available on the market varies widely, and there are still many...

Is it true that the higher the viscosity of a lubricant, the better?

First, it’s a misconception among car owners that the higher the viscosity of lubricating oil, the better. Lubricating oil viscosity is not only a basis for classifying lubricants but is also closely related to factors such as engine power, the degree of wear on moving parts, the sealing performance of piston rings, the amount of oil consumed during combustion, the ease of cold starts, and the temperature of engine components. If the viscosity of the lubricating oil is too high, several problems may arise: 1. The engine will have difficulty starting at low temperatures. When the oil viscosity is too high, the oil takes too long to circulate during cold starts. Although the oil pressure may be high, the actual flow rate of the oil is relatively low—mainly because the high viscosity impairs the oil’s pumping performance. Under these conditions, it becomes particularly easy for...

The Most Comprehensive Guide to Hydraulic Oil

For mechanized construction enterprises, the good or bad technical condition of construction machinery is a direct factor determining whether the enterprise can maintain normal production. In the case of construction machinery with hydraulic transmission systems, the proper functioning of the hydraulic system is a key indicator of its sound technical condition. Qualified hydraulic oil is the guarantee for the reliable operation of the hydraulic system, and proper maintenance is the foundation for ensuring its dependable performance.

Will leaving some engine oil behind damage the engine?

When car owners change their engine oil, they all hope that the old oil can be completely drained out. Often, they find that after adding a fresh batch of oil, there’s still some left over—some cars have more leftover oil than others. Does this mean the old oil wasn’t fully drained? Could incomplete oil drainage damage the engine? And why is it impossible to drain the oil completely? First, draining engine oil relies on gravity for it to flow out naturally. Due to the angle of the oil drain plug and the irregular structure of the oil pan, there will always be some oil that simply cannot flow out by gravity. Moreover, as engine oil is used over time, it accumulates many impurities, making it impossible to drain it completely. To illustrate this point, imagine filling a large basin with water and then adding sand into it.
