What kind of engine oil can be said to be a good engine oil?

SN grade fully synthetic motor oil. SN is the highest grade of motor oil, and fully synthetic motor oil is more durable than semi-synthetic motor oil or mineral oil due to the addition of functional additives. For example, the additive PAO, now everyone is using SN fully synthetic engine oil, and it is not expensive anyway.

Imported engine oil is better than domestic engine oil because the additive technology is mature. For example, the G T Magic Red engine oil I use now has a high PAO index because the company used to specialize in additives. If you want to know more, you can take a look.

Fully synthetic oils are best. Under normal conditions, fully synthetic motor oil can be changed every 10,000 km or every 12 months; Semi-synthetic oil can be changed every 7500 km or every 9 months; Mineral oil can be changed every 5000 km or every 6 months. Although fully synthetic motor oil is the most expensive, followed by semi-synthetic, due to the longer use time and the fact that synthetic motor oil is more beneficial to engine protection, there is an economic account.

What makes a good engine oil? You must understand the 5 major standards for choosing a good oil.

After buying a car, it is inseparable from maintenance, and the most conventional item in maintenance is the replacement of engine lubricating oil. The oil and oil filter element also account for the majority of the maintenance cost because they have to be replaced every time they are maintained.

Engine oil, known as the car's"Blood"This also shows the importance of engine oil for car maintenance, a good engine oil, can play a role in lubrication, cooling, rust and corrosion prevention, shock absorption and cushioning for the engine. On the contrary, choosing the wrong engine oil not only costs unjust money, but also fails to protect the engine well, not to mention increasing the noise of the car, and even wears out the engine. There are so many types of lubricants on the market today, what is the most suitable engine oil for car owners?

How to choose a good engine oil?

First, the first engine oil is a good engine oil.

The harm of fake engine oil is very great, not only easy to make the engine pull the cylinder, burn the tile, and even cause some sudden failures, which poses a threat to the safety of the driver. What's more, with these fake engine oils, if the vehicle fails, not only can not get the manufacturer's after-sales service, but also because the engine is the core component of the vehicle, if the engine is damaged, it will greatly depreciate the value of the vehicle! In the car aftermarket, which is full of fakes, the first step is to ensure that you buy it.

For car owners, if they want to avoid buying fake engine oil, it is the most reliable way to eliminate fake engine oil from the source, such as offline direct sales stores of brand engine oil.

Second, fully synthetic engine oil is a good engine oil.

According to the refining and synthesis technology, there are three types of engine oil: mineral oil, semi-synthetic, and synthetic oil. Unlike traditional natural products, in terms of grades: fully synthetic motor oil, semi-synthetic motor oil, mineral oil.

The stability and anti-aging ability of fully synthetic motor oil is the best, so there are often some high-end car brands that specify the use of a certain brand of fully synthetic motor oil.

For now, it's a little better, it's all synthetic.

It should be a better engine oil.

Of course, it is also necessary to fit the model of your car.

In addition to the most important thing is the slippery performance of the moisturizing hole, a good engine oil must also have the functions of cooling, sealing, cleaning, and rust prevention. As a result, the car engine is maintained faster and the service life of the car engine is extended. No matter what brand of engine oil, buying fully synthetic engine oil is the best choice, as long as it is an internationally renowned brand of engine oil.

The quality of the fully synthetic engine oil is better, the cold start is smoother, the fuel is more economical, the oil change interval is longer, the service life of the engine is extended, the maintenance rate is reduced, and the engine block is more trembling and clean due to the superior cleanliness of the synthetic engine oil.

Nowadays, there are many well-known brands of engine oil, both domestic and foreign, and the quality is different. Which engine oil is powerful is also a question that many car buyers are concerned about. The better engine oil is Shell oil, Castrol, Great Wall, Castrol, etc., the product quality of this well-known brand is good, the performance is more guaranteed.

At this stage, the vast majority of China's engine oil sales market is still occupied by international brands, and recently, there is a well-known overseas engine oil brand landing in China, that is, Eagle Flag engine oil. I heard that it was very popular with everyone when I first arrived, so how about the Eagle Flag engine oil? Let's take a look.

In addition to having the most important wetting performance, a good engine oil must also have the effects of refrigeration, sealing, cleaning, and anti-rust treatment, so as to maintain the car engine faster and increase the service life of the car engine. Engine oil is divided into mineral engine oil, semi-generated engine oil and full-generation engine oil, and the applicable engine oil should be used for different models. Mineral engine oil has slightly less characteristics in various fields, and today's vehicles are more likely to use generated engine oil, semi-generated engine oil is suitable for self-priming engine models, and full generation engine oil is more suitable for turbocharger models.

Founded in 1922, Eagle Flag Engine Oil is a highly intelligent manufacturer of grease, lubricating fluid and other automotive beauty categories in the United States and even all of North America. According to Daimler Fiat CHRYSLERMS-6395, Ford FordM2C946-A, GM6094M and other car factories to verify the quality, although the United States, its refined oil is customized for the Chinese sales market, making it more suitable for China's road conditions, to meet the requirements of 98% of models across the country.

Generally, we change the engine oil according to the use of the engine oil to decide whether it needs to be replaced, drop the oil on a piece of white paper, and then identify the oil use according to the oil color replacement judgment chart. With constant use, the oil will slowly deteriorate and be mixed with impurities.

1.Fully synthetic engine oil: Fully synthetic engine oil has better high and low temperature performance, longer oil change interval and is suitable for more severe car conditions, suitable for luxury high-performance vehicles, and is replaced at about 10,000-12,000 kilometers.

2.Semi-synthetic engine oil: The replacement cycle of semi-synthetic engine oil is generally about 8000-10000 kilometers, and the performance is moderate.

3.Mineral oil: This type of oil generally needs to be replaced after about 5000 kilometers.

Try to choose multi-grade oil, multi-grade oil has a better protection effect on the engine due to saving, long life and high efficiency. Due to the characteristics of multi-grade oil, there may be premature blackening and less oil pressure than ordinary oil during use.

Motor oil is something that everyone who owns a car can use. Good oil can lubricate the engine to reduce wear, prevent rust and corrosion, and cool it down, effectively extending the life of the engine. I'll be here today.

The level of engine oil search.

To know what grade of engine oil is the best, first of all, we need to know the grade about the engine oil As for the API grade and SAE grade, which of the two grades is the best, let's take a look.

API quality level.

API grade naturally distinguishes the quality of motor oil. There are more than a dozen grades of gasoline engine oil from Sa to SN, while the grades of diesel engine oil are Ca and SN. The higher the quality of the oil, the better the performance, especially the higher the fuel economy and grip.

Of course, it will also be more expensive. Generally speaking, regarding the API quality level, the letters should naturally be placed at the back, the lower the better, such as gasoline engine oil is the best].

SAE viscosity grade.

SAE viscosity grades are complex. Two-stroke oils (which can be mixed with gasoline) are SAE20 and SAE30 grades. SAE30 is generally used, but cars generally use four-stroke engine oil (which cannot participate in engine combustion), such as 5W30, where W

So is it true that the lower the number before the w and the higher the number after the w, the better the gasoline? Of course not. Viscosity grades are not the same as mass grades. The higher the quality grade, the better, but the viscosity grade should be the model's.

What grade of motor oil is best? Of course, the right oil for your own car is the best. Generally, the oil pack will be marked with API K1.
