Engine oil and transmission oil – is it possible to use the same?

A car, like a human being, requires the right elements to function properly. In addition to all the exterior parts, the interior of the car is also important. And yet many drivers do not know what is under the hood, or for what purpose oil is poured into the gearbox, let alone how it differs from engine oil. In this article we will dispel any doubts.

Transmission oil

Translation oils are extremely important substances in the car. Their quality and condition affect the wear of the transmission, and too rare replacements can cause mechanical damage. Thanks to the high degree of viscosity, they adhere to the parts inside the gearbox and ensure its smooth operation. While driving, gears, transmissions and other elements have direct contact with each other and it is thanks to the oil layer that they do not rub against each other, which could inevitably cause damage.

Manual transmission

For manual transmissions, oils in quality classes from GL-1 to GL-5 work well. The class of engine oil depends mainly on the additives that are in it and the level of load. For example, GL-1 class oils do not contain refiners. This type can be replaced with engine oil. In addition, they work well in older cars and with low exploitation.

In turn, the OIL CLASS GL-4, will be suitable for gearboxes with bevel and hypoid gears, which work at high speeds. In their composition, they also have a lot of additives that are designed to liquefy the operation of the box.

Viscosity is also important. Viscosity classes are usually given according to SAE (Society of Automotive Engineers). A number and corresponding digits are added to the abbreviation – from 70 to 250. To the four lowest is added the letter W, which stands for efficient work at negative temperatures.

How to care for a manual transmission?

In addition to proper operation, it is important to change the oil – once every 100,000 km it is even an obligation. If your car is already a few years old and you are afraid that the transmission has worn out a bit, it is worth using an additive to the transmission oil. The risk of a possible repair will certainly decrease.

Ceramizer CB – an additive to silence the gearbox, is used primarily to protect the friction surface during operation. It eliminates grinding and increases smoothness during gear changes. The addition to the gearbox effectively extends its service life. Thanks to this, you will not soon worry about the costs that will have to be incurred when replacing worn elements. Remanufacturing the gearbox has never been so easy – just add the product to the oil and hit the road. You will notice the first effects after driving 1,500 km.

Automatic transmission

The above classifications do not apply to oils for automatic transmissions. The torque converter clutch and control clutch system require oils with a lower viscosity than manual transmissions. These types of oils must have thermal stability, spread well at low temperatures, reduce friction and have high abrasion resistance. The classes of these fluids are described by ATF (Automatic Transmission Fluid). In Europe, ATF Dexron III is most commonly used.

How to take care of the automatic transmission?

First of all, do not pour engine oil into the automatic transmission. It works in completely different conditions, which is why it is so important to follow the manufacturer’s recommendations. Replacement is also important. It is worth following the indications of professionals. The first exchange is made between 80,000 and 100,000 kilometers traveled.

How to quickly choose the oil?

First of all, we need to know the exact model of the vehicle including the make, engine and year. Later, we determine the type and model of the gearbox, and then check in the service book what type of oil meets the standards required by the manufacturer. In this way, we will quickly and efficiently determine exactly what oil for the gearbox will be ideal.

Engine oil

The engine, as the heart of the whole vehicle, needs special treatment. Regular oil changes prevent damage and reduce the risk of breakdowns. Its main task is to provide lubrication to all engine components, between which friction arises. In addition, it cools it by absorbing excess heat.

Engine oil consists of a lot of mixtures that are to perform all the functions needed for proper operation. An important parameter is viscosity. As in the case of gear oils, those for engines are determined by the SAE classification. However, they differ in designation. It consists of three elements – two numbers and a letter between them. The first digit refers to winter conditions, the second to summer. The lower the digit, the easier it is to start the engine at negative temperatures. In turn, the higher the value of the summer parameter, the better the start at high temperatures. API classification is quality requirements. Other standards will have gasoline engines (S) and other diesel (C). The second letter standing next to the marking is quality. The further the letter in the alphabet, the higher the class oil.

How to take care of the engine?

To properly care for the engine, first of all, it is necessary to provide it with good quality oil and replace it in accordance with the manufacturer’s recommendations. It is important to ride with your head. Every engine wears out during operation. If your car has traveled many thousands of kilometers, it is worth considering what additives to engine oil to choose to regenerate it. The appropriate preparation will not only postpone the possible overhaul of the engine (the cost would probably be high), but also reduce oil consumption, equalize and silence the engine.

The ceramizer CS engine oil additive is a great solution for impatient people. Just add it to the oil and enjoy the first effects after just 250 km. For the next 1,500 km, do not change the oil – until now, the regeneration process will continue. The addition to the engine oil makes it easy to start it. . It also reduces fuel consumption by up to 15%, increases compression pressure and reduces emissions.

Similarities and differences

Both engine and gear oils are designed to effectively lubricate components, protect metal parts from rust and maintain cleanliness in places where there is no direct access. The difference comes in technology. The gears work under high loads. They transfer torque from the drive shaft to the passive shaft, which means that the oil in the transmission is subjected to very high pressures. This pressure is much lower in an engine that uses engine oil – which is why oil technologies differ from each other.

Each car has a slightly different specification, so before you decide to change the oil in the gearbox or engine, it is worth looking at the owner’s manual and listening to the manufacturer’s advice. Only in this way will you provide your vehicle with the best working conditions. It is also worth supporting it from the inside using additives that will improve its work and provide additional protection.
