Common errors in the use of automotive lubricants inventory

Lubricants in automobiles can be said to be a high-usage oil in maintenance. It not only protects the role of the engine, but also saves the cost of gasoline. It can be said to be more than one thing; but if used improperly, the lubricant will not only If you do not achieve the effect of conservation, it will damage our car. Today, I will introduce here to the four misunderstandings on the use of lubricating oil and I hope that it will help the majority of vehicle owners.

Misunderstanding 1: Lubricating oil can increase

The amount of lubricant should be controlled between the upper and lower tick marks of the oil dipstick. Because too much lubricating oil will enter the combustion chamber from the gap between the cylinder and the piston to form a coke combustion. These coke deposits will increase the engine compression ratio and increase the tendency to produce knocking. Coking in a red hot state in the cylinder will also cause premature combustion. If it falls into the cylinder, it will increase the wear of the cylinder and the piston, and it will also accelerate the pollution of the lubricant. Secondly, too much lubricating oil increases the stirring resistance of the crankshaft connecting rod, which increases the fuel consumption.

Misunderstanding 2: When the oil becomes dark, it is time to change the oil.

This understanding is not comprehensive. For lubricating oils that do not add a clear dispersant, the color blackening is indeed a sign that the oil has been seriously deteriorated, but the lubricants used in Hyundai Motors are generally added with a decomposing agent. This clearing agent cleans the film and black coke adhering to the piston and disperses it in the oil to reduce the formation of high-temperature deposits in the engine. Therefore, after the oil is used for a period of time, the color tends to turn black, but this time The oil has not completely deteriorated.

Misunderstanding 3: Lubricants often add no change

Regular inspection of lubricants is correct, but supplementation without replacement can only compensate for the lack of oil, but it cannot fully compensate for the loss of lubricant performance. During the use of lubricating oil, the quality of the lubricating oil will gradually decrease due to pollution, oxidation, etc. At the same time, there will be some consumption and the quantity will decrease.

Misunderstanding 4: Large use of additives

A truly high-quality lubricant is a finished product with a variety of engine protection functions. Formulations already contain a variety of additives, including anti-wear agents, and lubricants are the most balanced formulas to ensure full performance of all kinds of performance. Adding other additives on their own will not only bring additional protection to the vehicle, but will also react with the chemical substances in the engine oil, resulting in a decline in the overall performance of the engine oil.
