Gearbox oil lubricates the gear discs and ensures their reliable operation, allowing for quiet and smooth gear shifting. Depending on the road conditions, the car needs the right amount of traction, and the crop regulates the torque through the gears. At low speeds, heavy gears are required, and as speed increases, it shifts to lighter gears.

There are 2 types of car gearbox: “Mechanical” and “Automatic”

• With a mechanical crop, the gears are shifted through the console. When starting to move, engage first gear and then shift to light gear.
• Auto crop will do all the work for you, such as pedaling and changing gears. All you have to do is look at the road and drive. Through a variety of sensors, solenoid valves, hydraulic power and computer control, the gear is engaged and shifted according to the road conditions and the car’s speed.

Different types of oil are used for these 2 types of gearboxes.

Engine oil is responsible for lubricating engine mechanisms and preventing engine energy loss, heat loss, wear and tear, and overheating.

The instructions issued by the manufacturer of the car indicate what type of oil to use. Cars use different types of oil depending on the engine design and motor capacity.

Viscosity is an indicator of the quality of internal friction between the surfaces of oil molecules. This quality decreases as the temperature increases and increases as the temperature decreases. If the viscosity is too low at high temperatures, the strength of the oil film on the friction surfaces in the lubrication system and the pressure in the system will not reach the required level. But in winter, if the viscosity of the oil is too high, the engine cannot be started because the starter cannot turn the crankshaft, and if it is started, there will be a lack of oil in the first few minutes, and the oil will not go through the lubrication system. In accordance with the above conditions, the quality of engine oil:

• Winter oil

Its low viscosity makes it easy to start when cold.

• Summer oil 

Due to its high viscosity, it reliably lubricates the engine at high temperatures.

• Four season oil

It refers to the oil with winter-like viscosity at low temperatures and summer-like properties at high temperatures. It is characterized by creating a quality that does not freeze in the cold and does not become too liquid in the heat due to the addition of special additives.

In Mongolia’s harsh climate, all-season oil is not suitable, and it is better to change the oil for that season in time.

Guaranteed engine oil has the following main advantages:

• When the engine is running, the parts rub against each other. The oil forms an oil film on the parts and prevents dry friction
• Prevents overheating by absorbing heat from engine operation
• Acts as an insulator between the piston and the cylinder wall
• Prevent corrosion
• It is responsible for cleaning the dirt that is generated in the engine

The brake fluid in the car transmits the pressure that occurs when you step on the brake pedal to the brake pads. In other words, because the brake fluid has a non-shrinkable property, it is used in the braking system to generate pressure using this property. Brake fluid is designed to withstand temperature changes.

Features of guaranteed brake fluid:

• Corrosion and life of rubber parts will be extended
• Oily
• Can withstand overheating and freezing

Official brake fluid works reliably when driving, and low-quality brake fluid does not meet the standards and can reduce the braking ability of the car and cause accidents.

A belt is a flexible rubber material that mechanically connects two or more rotating shafts. The belt located at the front of the motor, which ensures smooth operation of the engine and keeps all rotations at the same time, is called the front belt.

Fake belts are the same length as the warranty belts, but are made of different materials, stretch over time, cause the engine to fail, waste more gasoline, and even more so lead to the risk of breaking the engine.

A cracked or torn belt can break without indicating an error on the control panel and cause major damage to the engine. That’s why it’s important to have your car serviced regularly and replace worn out belts with new warranty belts.
