What is the Difference between Transmission Oil and Axle Oil?

What is the Difference between Transmission Oil and Axle Oil

Did you know that engine oil has an important role to protect and make the engine work normally? In vehicles, there are two types of oil, namely axle oil and transmission oil. From a physical point of view, the two are almost similar, so many do not understand the difference between transmission oil and axle oil.

Actually, transmission oil and axle oil itself have almost the same function, namely to protect several axle components such as gears, drive pinions , and so on. Although the function is almost the same, the roles of the two oils are different, you know. So, to find out the difference between transmission oil and axle oil, consider the following explanation.

Definition of Transmission Oil and Axle Oil

There are still many people who misinterpret transmission oil and axle oil. In fact, not a few people are almost mistaken in understanding the two types of oil. Transmission oil itself is a lubricating oil that works to lubricate gear parts and also several other components to prevent wear and tear. In general, there are several types of car transmission oil that are used, following the type of car used.

While the axle oil is a lubricating oil used to lubricate several parts of the axle such as the pinion driver, ring gear , and so on. The type of car axle oil itself also has several types and is adjusted to the type of car used.

Difference between Transmission and Axle Oil

Although they both function as lubricants, in fact transmission oil and axle oil have significant differences. So what is the difference between each of these oils? To find out, see the following explanation.

Oil Function Difference

Although both have a function as a lubricant, the functions of transmission oil and axle oil are quite different, you know. As previously explained, the function of transmission oil is to lubricate the engine parts of the car's transmission such as the transmission shaft, shifting gear, and also the gear so that the transmission components continue to work properly.

While the function of the axle oil is to lubricate the engine components of the axle parts such as side gear, ring gear, pionin drivers , and so on so that these components work well and are not easily worn out. So, after you know it, make sure you don't use the wrong type of oil for each engine component so that the car engine runs properly and normally.

How Oil Works

As you already know above, although they both work as lubricants, transmission oil and axle oil have different functions. Even the workings of the two oils are also different.

In transmission oil, the oil works by changing the ratio of engine speed or gear ratio. In the car's gear system itself, there are many components that rub against each other, therefore the transmission oil will lubricate these component parts so that the car's performance remains stable.

While the axle oil, the oil works by maintaining the stability of the car when running, channeling the rotation of the wheels from the axis and regulating the speed of the wheels when turning. Therefore, axle oil makes all components of the car work better and keeps the car going stably.

Oil Measure

Each part of the car engine has different oil requirements depending on the work intensity of the car engine. Therefore, transmission oil and axle oil will certainly require different levels of oil.

In general, a car will require transmission oil of 1 to 1.2 liters in a certain period of time. As for the axle oil needed as much as 2 liters. However, this difference is not a definite benchmark and is only a comparison because the need for oil will be influenced by the intensity of use of the car itself.

Oil Change Time

The important thing for you to know is when to change transmission oil and axle oil. Because if it is not replaced for a long time, it is feared that the oil will run out and the car components will not work properly.

Basically, changing the transmission oil and also the axle oil has the same time interval, namely when it reaches 40,000 km and also multiples thereof. However, for some automatic cars, the transmission oil itself can be replaced when it reaches 80,000 km.

Signs of Transmission Oil and Axle Oil Need To Be Changed

Each car component has a limited age, where when the age of the component is old, the component must be replaced immediately so as not to affect the car's performance. Same as transmission oil and also axle oil. The two oils have their own time interval where the car will show signs that the two oils need to be changed. To find out, see the following explanation.

Transmission Oil Signs Need to be Replaced

As explained above that transmission oil has a limited life, that is, when it reaches a distance of 40,000 km, you need to change the oil. The following are characteristics of car transmission oil that must be replaced.

1. Car Gear Feels Heavy

When the car's gear feels heavy when moved, there are several possibilities that occur. If it wasn't for the clutch lining running out, it could be that the transmission oil has started to run out. When this happens, it could be that the exhausted transmission oil makes the clutch wear out. Therefore you will find it difficult to change gears.

2. Buzzing Sound from Car Transmission

A sign that appears when the transmission oil needs to be changed is that you will hear a buzzing sound coming from the transmission of the car. Every car engine will certainly rub against each other when working, when the transmission oil runs out, a friction sound will appear even louder and rougher.

3. Oil Color Change

A fairly obvious sign when the transmission oil needs to be replaced is when you find the oil color has changed. Usually old oil will turn black. Therefore, immediately change your oil when the color of the oil has turned cloudy or black.

Axle Oil Signs Need to be Replaced

Apart from transmission oil, the axle oil on the car also needs to be replaced. Because if not, then things will happen that are quite dangerous. When the axle oil needs to be replaced, there will be signs from the engine indicating that the oil has run out or needs to be replaced. Following are the characteristics of the car axle oil that must be replaced.

1. Strong Vibration In Cars

The strong vibrations that occur when you get into the car will be felt even if you are on a straight or winding road. This happens because the oil that should lubricate the axle is no longer available so the performance of the axle engine is reduced and the engine will rub against each other causing a very pronounced vibration.

2. Burning Aroma

Another characteristic of the axle oil that needs to be replaced is that you will smell a burning smell coming from the axle part of the car. The burning smell appears because the axle oil is dirty or exhausted. Therefore, when you smell a burning smell from the axle, immediately check your axle oil.

3. Wheels are difficult to control

The axle oil functions to lubricate the axle gear parts so that the wheel performance will function normally. However, when you feel the car's wheels are difficult to control, it could be that your car's axle oil needs to be replaced. This happens because the axle oil that has run out or is dirty will affect the rotational speed of the car's wheels.

Those are some explanations about the differences between transmission oil and axle oil. By understanding the differences, you can take better care of your Hyundai vehicle. 

So, apart from understanding the differences between some of the oils in your vehicle, it's also important for you to change your oil regularly, OK? Consult all matters related to your vehicle maintenance at the nearest Hyundai outlet and make your vehicle perform even more attractive!
