How to recognize a car using fake oil
Using fake oil will make the engine "struggle" to support the entire vehicle. At that time, the friction force is greater than normal, leading to rapid damage to the vehicle, typically emitting strange noises.
It is really difficult to distinguish between fake and real oil, especially for those who do not know much about these types of oil. According to auto experts: Only when used in a vehicle, leading to strong friction causing the engine to heat up, then you will know that the oil is fake and of poor quality. With the naked eye, it is impossible to detect... At the same time, using fake oil will affect the entire operation of the vehicle.

When using real oil, there will be no residue at the bottom of the tank. |
Internal combustion engines operate on the principle that a mixture of gasoline and air is burned in the combustion chamber by an electric spark from a spark plug.
The power generated from this combustion process makes the piston move forward in the cylinder and through the transmission mechanism rotates the rear wheel.
First, the oil has a lubricating effect, helping the piston move up and down smoothly and gently in the cylinder. The engine is made up of many metal parts such as pistons, camshafts, valves, etc. When the engine is running, the friction between these parts is very large. The pump system will spray oil into every corner inside the engine to create a smooth cushion on the contact surface between the parts, reducing friction and increasing operating efficiency. At the same time, limiting direct contact between parts helps minimize wear on metal surfaces, protecting and increasing the life of the engine.
In addition, oil helps cool the engine when it is running a lot, sealing the gap between the piston and the cylinder wall so that the pressure generated during the fuel combustion process is not lost. At the same time, it washes away and cleans soot and rust layers from the engine.
Therefore, when using fake oil, the engine has to "work hard" to support the entire vehicle. This increases friction, leading to engine noise and not being as smooth as usual. It does not lubricate the engine well. When all the old oil is drained, the remaining amount of adhesion is very little, so when replacing with new oil, it will not affect the vehicle's engine much.
