Apart from the motor oil that your car needs, which is also known as lubricants, there are many other types of oil that you must be aware of.
Gear oil is one of them where they are used for transmissions. Depending on the type of transmission your car is using, there are specific grades and types that you must use. Known also as transmission fluid, it is used to ensure that the gear change in your car is efficient and at its best performance. You will know that it is time to change when (in automatic cars) there are jerks when the gear changes. Otherwise, it is best to change your gear oil every 50,000 km.
Another type is Brake Fluids. It is typically a type of hydraulic fluid which is used to transfer force into pressure so that the brakes are working property. Most of the brake fluids today are made using glycol-ether base while there are also mineral and silicone made ones. Brake fluids are very important as they usually determine the strength of the brakes and to ensure that they work efficiently. In most cases, it is advised that brake oils are changed every 80,000km or earlier if possible.
The Power-Steering Fluid is another type of liquid that you must know. These hydraulic fluid basically provides power for the power steering which means that if your car does not have this, then it is not necessary. Take note that it might be the cheapest fluid that you will have to pay for but it is by far one of the most important. This is where it provides the steering and manoeuvrability of the vehicle. Changing the fluid would be best every 50,000km although sometimes your mechanic might advise you to do so earlier.
Always remember that changing these fluids should not be done after something happens or becomes faulty. Always follow a schedule just like you would follow your servicing schedule.
