[China Glass Network] Motor oil, antifreeze, and glass water are the three common items for car maintenance. They are always taken out and said when each season is replaced. Their importance is self-evident. The key to their use is to choose. So, how to choose high-quality products from the variety?
Motor oil
When selecting oil, please observe and identify the oil quality from the following aspects.
The first thing to look at is the color of the oil. The domestically produced bulk machine oil is mostly light blue, with bright luster and even flow. Any color that is uneven in color and has a different color line when flowing is a fake or deteriorated motor oil. The color of the imported oil is golden blue, crystal clear, and the oil barrel is made exquisitely. The edges of the pattern code are clear and tidy, without leakage. Color and overlap, otherwise it is a fake.
Next, smell the smell. Qualified oil should have no special odor and only a little fragrant. Any oil that has a large odor and odor is a deteriorated or inferior motor oil and cannot be used.
To identify the oil that is being used, we must first look at it. When we maintain the oil, we must observe the flow of the oil. The good quality oil flow should be slender, even and continuous. Next, we have to pinch the old oil with the thumb and index finger repeatedly. The good quality feels lubricity, less wear debris, and no friction. Then we try again, that is, take a clean white filter paper (a little more expensive facial tissue paper), drop a few old oil on the paper, after the standby oil leaks, the good quality oil has no powder, touch it by hand. It is smooth and has a yellow mark.
antifreeze
Antifreeze is also called car antifreeze coolant. It has the functions of antifreeze in winter and anti-boiling in summer. It can prevent corrosion, scale and protect the engine's cooling system, improve heat dissipation and improve engine efficiency. A good and qualified antifreeze first has a low freezing point and a high boiling point. At the same time, it should also have a small viscosity, good fluidity and no scaling during use. Antifreeze also protects the car's cooling system, and at least it does not cause corrosion of the parts.
Generally, the inferior antifreeze has the following three characteristics: First, it has an odor. The main component of the antifreeze is ethylene glycol, which has no odor. The main raw materials for inferior antifreeze are industrial methanol, or chemical wastes such as various miscellaneous alcohols. These things generally have a pungent odor and strong volatility.
Second, there are traces of spills at the bottleneck. The outer packaging of inferior antifreeze is often very beautiful, but these manufacturers have no professional canning equipment, and the canning of manual canning is not good. After the transportation, the bottleneck often has leakage marks.
In addition, it is recommended that you check the factory name, factory address, telephone number, production date, freezing point, boiling point and other items on the package. The regular products are well-marked and the writing is clear; the fake and inferior products are easy to erase and the markings are inconsistent or incomplete.
Glass water
High-quality glass water is made of deionized water and various environmentally friendly additives. It has functions such as decontamination, antifreeze, antistatic and anti-corrosion. Some better high-quality glass water, with fast melting snow melting, anti-glare, anti-fog and other properties, has a significant effect on improving driving safety.
Then we should pay attention to the selection of glass water: good glass water foam is very rich, and the ability to remove glue is super strong. Degumming is mainly based on various surfactants, and the more the surfactant is, the more the liquid foam is, and the better the cleaning effect is. When choosing glass water, be sure to shake it to see if the foam is rich. The foam from high-quality glass water is not only rich and fine, it is a typical anionic surfactant (environmentally friendly, biodegradable), if you choose the glass water The foam is very large (just like the washing powder is washed out), which means that the glass water is not environmentally friendly.
Engine oil is more familiar and valued. Antifreeze and glass water are much less important than motor oil. Many people even use tap water instead of them. It is worthless to save a few small dollars at the expense of the engine and front wiper. Still insist on using it as well.
