5 signs your car needs an engine oil change
(Baonghean.vn) - Oil will help the car engine run more smoothly and perfectly. If your car shows one of the following signs, it is likely that your car needs to be checked and have its oil changed.

1. The car makes a loud noise when starting.
When the car starts running, oil is pumped from the tank to the cylinders, after a while, the new oil will become dirty and "lose its quality" due to the temperature and friction of the car's parts. Therefore, the car will tend to make louder noises and be more difficult to move.
Therefore, when the car makes an unpleasant noise when starting, it is a sign that the oil is low and needs to be replaced.

2. Slow car
Another consequence of running out of oil is that the car will run slower than normal, the reason is because the friction between the piston, ball and bearing increases. Therefore, when the car shows signs of "sluggishness", car owners should check carefully and there is a high possibility that the car has run out of oil.
3. The car accelerates slowly
When the engine is perfectly lubricated, the car runs very smoothly. However, when the oil turns black or runs out, the car cannot move smoothly, especially when the car accelerates. At that time, the car is very sluggish and the engine is more "stubborn". This is a great signal that the oil tank in the car needs to be checked again.

4. Engine rattles
When your car engine makes a rattling noise, the cause may be poor oil quality. If left for too long, the engine bearings can fail at any time.
Therefore, car owners need to pay attention because this noise comes from inside the engine and gets louder and louder as the car moves faster. Therefore, this is also a signal that the oil in the car needs to be replaced promptly.
5 Oil warning light on
When the oil warning light comes on, no car owner wants to ignore this signal. Because it signals that the oil pressure in the car is too low compared to the standard for the car to operate safely. Therefore, the first thing car owners need to do is to change the oil immediately.

How often should the oil be checked?
Normally, car owners should check the oil level of their car at least once a month and repair it immediately when the oil tank shows signs of leakage. The common step to check the oil level for users is usually the dipstick method.
In the dipstick test, park the car on a level surface, turn off the engine, insert the dipstick into the oil tube and press it down as far as it will go. Then pull the dipstick up and quickly observe the oil stains on both sides.
Each type of stick has a different way of measuring the amount of oil such as 2 holes, the letters L (Low) and H (High), from Min and Max... If the oil streak is between the 2 ends or in the cross-hatched area, the vehicle still has enough oil. If the oil streak is below the last end, the vehicle needs to change the oil immediately.
In addition, you need to pay attention to the color of the oil. If the oil is black or brown, your car is still normal. If the oil is light milky white, the coolant has leaked into the engine. If there are metal particles, the engine is damaged and needs to be taken to the workshop for inspection and repair.
