With the progress of society, there are more and more private cars, and there are also more and more novice drivers and drivers who only know how to drive but don't know how to maintain or repair cars. Often, when cars have problems, they are sent to 4S dealerships or repair shops. If they encounter unscrupulous merchants, they become leeks themselves. If they encounter those with poor technology, it is likely that the money is spent and the problem is not completely solved, posing great safety hazards.

I don't know when it started, but there has been a saying in the repair industry that whenever there is a problem related to starting a car, the first thing to consider is the oil issue. If you burn oil, can't start the car, the car shakes, the engine alarms, and so on, the result is: "The oil you use is not good!" Especially if this problem occurs again after just maintenance, this type of oil is definitely out of control. What's even more magical is that in many cases, when a new engine oil is used, the problem is alleviated and temporarily resolved, which makes more sense and cannot be explained clearly.

As for the issue of burning engine oil, we have already made it very clear in the previous issues. Burning engine oil is a very complex problem that requires consideration of various factors such as engine technology, vehicle condition, and engine oil. As long as it is not the use of inferior engine oil, it has little to do with the engine oil. Let's talk about the reasons for the difficulty in starting in winter.

With the arrival of winter, there must also be problems such as inability to start or difficulty starting. If you encounter such problems, please check the ignition system, such as spark plugs, batteries, starters, circuit buckles, and the entire wiring for any problems. Nowadays, fully synthetic engine oils have very good fluidity, so it is unlikely that the problem of engine oil will cause the car to not start. Of course, if it is in extremely cold areas, it is recommended to use 0W or 5W engine oil for easier cold starting.

Below, we will comprehensively analyze two important indicators related to engine oil and cold start:

【 Wells Classroom 】 Pouring Point, Low Temperature Dynamic Viscosity Science Popularization

Firstly, pour point is an important indicator of engine oil, which is a temperature value that directly determines the minimum temperature at which the product can maintain liquid flow. That is, the lowest temperature at which engine oil can maintain good circulation in low temperature environments and winter without solidifying. The smaller the negative value, the better the anti low temperature effect of engine oil in low temperature conditions and winter. According to the test report, this test indicator is not higher than -25, while the actual test result of Wells products is -31, indicating that the pour point of Wells products is at least 6 ℃ higher than the quality standard. In fact, Wells products have excellent anti low temperature effects.

Secondly, the low-temperature dynamic viscosity, measured in MPa. s (millipascals per second), is mainly aimed at the ability of the product to start the vehicle smoothly under standard low-temperature conditions. Simply put, it refers to the cold start ability in low-temperature environments and winter. This data has a reference value for comparison. The standard reference value in this inspection report is not more than 7000, and the smaller the actual test value, the better the low-temperature start effect of the vehicle (provided that the vehicle's starter and battery are in good condition). It is obvious that the actual test result of Wells products is 3290, which is even lower than half of the standard value. This fully demonstrates that using Wells products can smoothly start the vehicle within the measured temperature. That is to say, Wells products have excellent cold start performance in low temperature environments and winter. Through the comprehensive analysis of two indicators, it can be concluded that Wells products can effectively protect the engine and achieve fast starting effects in low-temperature environments and winter use.

In summary, taking the use of Wells fully synthetic engine oil as an example in winter, if the viscosity of the oil is used correctly, there will be no problem of difficult starting or inability to start the car due to oil reasons. At the same time, please believe that other brands of legitimate products will also strictly follow the production standards, which is why I mentioned earlier that if there is a problem of difficult starting, please check the ignition system. In the next issue, let's talk about the issue of cold start car shaking.
