The most famous brands of this oil are Shell, Castrol and Mobil. Which one should we choose? Today, I will share with you the unique skills of various brands, which are particularly powerful.
What is Shell's trick?
Good cleanliness
The most prominent feature of shells is cleanliness. After the engine is used for a period of time, it is easy to produce sludge and carbon deposit.
Heineken engine oil has a special formula to deal with these things, which can take out the dirty things in your engine at any time and then filter them out with a machine to keep your engine in better working condition.
The dynamic response is also faster.
So what are the benefits of this technology in our actual driving? As soon as we step on the accelerator, the dynamic response is faster, which is regarded as Shell Oil's ace in the hole.
So you can see that F 1 racing cars, various fuel-efficient and durable Japanese cars and other engines with high assembly accuracy have a relatively large proportion.
What unique skills does Castrol have?
Star endorsement
Then let's talk about Castrol again. What impressed Castrol most was all kinds of celebrity endorsements, which was obviously not a characteristic technology.
Good cold start protection
Its unique skill is to better protect the cold start of the engine, and in principle, the low-temperature fluidity will be better, plus some special formulas.
It's a bit like hanging a glass when we drink white wine. Your car has stalled, but there is still a small amount of oil stuck to it, which will not completely flow back to the oil pan due to gravity.
Then when you restart the next day, there will be an extra layer of oil for protection.
For this friend who has a cold weather, or a difficult cold start and an old car, it is better to choose Castrol. Listen to the name, antimagnetic. What do you mean? It's wrong to smoke on it.
What's Mobil's trick?
Insist on synthetic oil technology, like to take technical flow.
Then let's talk about Mobil. Basically, Mobil prefers to follow the technical process and has always insisted on developing this synthetic oil technology.
The biggest advantage of its synthetic oil is that it is not easy to crack and the oil change cycle is relatively long. At the same time, its sports performance is better and its high temperature resistance is quite good. It sounds like there are many advantages, but they are all produced by one technology.
That is to say, they developed a base oil called poly-α-olefin, which is a patented technology of ExxonMobil, and the acronym of the local dialect is PAO.
It comes from the gas in crude oil, ethylene and propylene dispersed by natural gas, and then polymerized and catalyzed by professional equipment. Anyway, it is a pair of complex chemical reactions, and then refined.
Its base oil molecules are arranged very neatly, and then its ability to resist external variables is very strong. What extrusion, oxidation, thermal stability, viscosity change, resistance are all better, then this is the trick, he won all over the world.
Good grades in sports
Many manufacturers who choose Mobil engine oil tend to pay more attention to performance. For example, many German cars, fast performance cars, and more choices of Mobil.
There are also some such economical cars, and the oil is changed once every six months. 10000 km, 15000 km oil change, all choose Mobil.
The oil change cycle is relatively long.
If Mobil is a little better, with its long-term mechanical filter, it can change the oil once every 25 thousand kilometers, which is quite durable. Therefore, a friend who uses Mobil oil, 4S shop tells you that 5000 is a bit overqualified.
How to choose these three brands?
Always keep the car in good condition. Choose a shell.
To sum up briefly with you, the accuracy of the car is very high, and it should always be in good condition. It is best to choose a clean shell. The disadvantage is that it is not durable and needs to be replaced frequently.
It is difficult to choose Castrol for cold start in cold regions.
So Castrol is really right to choose this one for friends with colder climate or friends with older cars and difficulties in cold starting in the morning.
Focus on performance and economy, choose Mobil.
If you think this car has better power, better high temperature protection, and then it is economical and durable, Mobil may be a better choice.
