What is the best engine oil for cars in the southern region

Engine oil is by no means a higher grade, the better... The number before w represents low temperature fluidity, so it can be 5w or even 10w in the south all year round... Unless the extreme cold areas in the north are 5w all year round, it is no problem, especially cold places can use 0w, and in summer, you can consider 10w or even 20w...

The latter number is the kinematic viscosity at 100 degrees Celsius, the viscosity is high, the fluidity is poor, the viscosity is low, the fluidity is good, but the low to a certain extent will attenuate and affect the lubrication... So the oil index is just right... Japanese 30 is enough, if it is the United States, it is recommended to use 20 (the number after W), the mileage is high, or the Odyssey can be used for a long time in a high temperature environment with high revolutions, although the higher speed is theoretically necessary to use a lower viscosity oil, but due to the different engine design, the factory recommends using 30, the same mileage is high, or you need to use a car with high speed in a high temperature environment for a long time, you can consider using 40 Many systems of the engine rely on oil to lubricate and work, and the viscosity of the oil used is too low to lead to insufficient lubricationIf it is too high, it will lead to insufficient fluidity of the engine oil, which will not supply engine lubrication, resulting in high water temperature and premature wear of the engine.

In fact, the danger of too high viscosity of engine oil is higher than too low... But blindly using high-grade motor oil is quite stupid... Some people always like to complain about the high water temperature of American cars, which is indeed the case compared to Japanese cars, but if you listen to the foolishness, you use 40 engine oil from the beginning of a new car...

The water temperature is not old and high, so it's strange... The newer car uses 20, and if the mileage is 10 tens of thousands, use 30....The problem of water temperature will be significantly improved, and the engine will run much smoother. . .

There are many things in the world that are not as big as the numbers ... If you are a new car, I recommend Castrol 5W20... If the number of kilometers is high, it is recommended that Castrol 5w30...

In addition, it is a matter of opinion whether to use a fully synthetic motor oil. Fully synthetic is not everything good (for example, many high-performance cams are actually better to use mineral oil after they are modified, at least they should be run in with mineral oil when running-in).However, in terms of mainstream total synthesis, personal experience shows that the carbon deposits of Kim Mobil and Shell are much higher than those of Castrol Extreme, and the engines used are very clean.

FYI. As for Amsoil, Red Line, Motul, Torco, HKS, Speed Master... Let's choose for yourself, Torco SR5, 2,3 thousand kilometers for a change is quite good...

amsoil and red lines are actually average. As for Speedmaster and HKS, it should be good... But all racing oils are high-performance oils, roughly speaking, high-performance oils are not long-lasting oils, in fact, the higher the performance of the oil, the faster the decay...

Therefore, it is still a brand like Castrol that has a good balance of performance and durability, and is suitable for civilian use.

1. It is okay to choose 5w 30 or 5w 40 engine oil in the south, because the winter temperature in the south is not as cold as in the north, so it is not necessary to choose 10w w w 40 and other lower viscosity oil in the north. In the summer, the south is hotter than the north, so there is no need to use oil with a high viscosity grade to increase lubricity.

2. In 5W-30, "Yuan Mao stupid W" represents "winter" which means winter use, and the 5 in front of "W" represents the viscosity under low temperature conditions, the smaller the number, the stronger the fluidity at low temperature, and the stronger the ability to withstand cold. "30" refers to the viscosity at 100, and the higher the number, the higher the viscosity and the stronger the ability to withstand high temperatures. Hail accompaniment.

3. SAE is the English abbreviation of the Society of Automotive Engineers, and the SAE grade represents the viscosity grade of the oil. SAE30 and SAE40 are single-grade oils, and SAE10W 30 and SAE15W 40 are multi-grade oils. Among them, the higher the number in front of w, the lower the viscosity at low temperatures, and the better the protection ability of the engine during cold start; The number after w is an indicator of the high temperature resistance of the oil.

4. The difference between W-30 and 10W-40 is: the stronger the fluidity of the engine oil at low temperatures, the different the ability to withstand cold. Viscosity at 100, the higher the number represents the higher the viscosity and the ability to withstand high temperatures.

Compared with other parts of the country, the average temperature of the south is higher, although this is the case, but the engine oil of the motorcycle is also to distinguish between the summer oil and the winter oil, it is best not to mix them, because the role of summer oil and winter oil as an engine is different, and the biggest difference between them is that the viscosity of the oil is different.

Because of the displacement, the applicability of this 125 small displacement motorcycle to lubricating oil is relatively wide, so that is to say, whether it is mineral engine oil or fully synthetic engine oil, it can be used, but after combining the characteristics of the vehicle, it is recommended that riders use mineral engine oil lubricating oil, as long as they ensure that the lubricating oil is replaced regularly. In general, this mineral lubricant is still relatively cost-effective for this type of vehicle.

Considering that the local temperature is slightly higher than that of the rest of the country, it is recommended that riders can use 10w-50 minerals or fully synthetic engine oil lubricants in summer, and 10w-30 mineral or fully synthetic engine oil lubricants in winter. However, riders can also choose engine oil according to the specific local temperature conditions, or choose 15w-40 mineral or fully synthetic engine oil lubricant is also a good choice.

So when it comes to the choice of lubricating oil brand, it mainly depends on the consumption habits of the riders, why do you say that? Because if riders pay more attention to the lubrication effect of the engine oil, then you can choose international brands, but in comparison, the current domestic motorcycle oil lubricating oil effect is also good, and the cost performance is high. So if you pay attention to the cost performance of engine oil, you can choose domestic brand engine oil.

Through the above analysis, riders can see that what kind of oil lubricant they want to choose is mainly related to the local temperature conditions, the performance of the vehicle, and the choice of the brand. What do you say? What kind of oil and lubricant do you choose for your motorcycles?

Hello, this one can be used with five W-30 models on it.

Do you mean what kind of oil to add at different temperatures? First of all, look at what grade of engine oil is recommended for the engine, rather high than low, in order of SG, SJ, SL, etc., and then the brand of engine oil. There are certain differences according to different ambient temperatures, for example, you can use engine oil starting with 5w in winter, such as 5w-30 In summer, you can use engine oil starting with 15w, such as W15-40, if there is no special cold situation, use engine oil starting with 10w.

Finally, the most important thing is to replace it according to the number of kilometers, after the kilometers are up, the performance of the oil will decrease, especially at high temperatures, and there will be a small amount of impurities to bring wear to the engine if the oil is not changed for a long time.

It is possible to choose NGK engine oil with 5W-30 5W-40, which has anti-wear and anti-oxidation ability and is suitable for high-performance engines.
