Misconception 1:
Worries about high engine cooling water temperature and not afraid of low temperature.

Make every effort to find the cause of high engine cooling water temperature. If the water temperature is low, it is considered normal. In fact, low engine cooling water temperature in modern cars poses a great danger. It can lead to insufficient combustion of the mixture, reducing power, increasing fuel consumption, poor lubrication, and even excessive emissions.
Misconception 2:
The more oil you add, the better.

Keep the idea that it’s better to add more engine oil than less. Adding less oil can easily burn the bearings, so adding more oil doesn’t matter. In fact, adding too much engine oil can still cause harm to the engine, especially for inclined engines and V-type engines. It not only increases the rotational resistance of the crankshaft and connecting rod, but also increases the amount of oil splashed onto the cylinder wall, causing an increase in carbon deposits in the combustion chamber. Adding too much engine oil will reduce engine power, increasing wear and excessive emissions.
