Can gear oils from different manufacturers be mixed?

Can engine oil and gear oil be mixed?

There are many common components in the composition of engine oils and transmission lubricants. However, this does not apply precisely to the identical composition of both liquids. It's just that each of these oils cannot be called a unified product. In other words, according to existing rules and recommendations, even without taking into account very similar characteristics, the answer to the question of whether engine and transmission oil can be mixed is negative. In the most extreme cases, this action is allowed. But as soon as the “native” liquid is found, the gearbox system will need to be cleaned of the mixture.

Danger of mixing lubricants

Careless mixing of several types of gearbox oils can cause very serious consequences. But the main ones will be related to the design features of the box.

The work of lubrication in gearboxes and gearboxes occurs at low temperatures, relative to the operating conditions of engine oil. However, liquids under different brands can have many differences in chemical composition, and certainly in terms of additives. This circumstance can have an impact on the appearance of an unpredictable reaction during mixing, causing the appearance of sediment, which will simply create a blockage in the system. This is true for variators and automatic machines. The fact is that the design of the gearbox provides for the presence of a filter. This part is very quickly clogged with reaction products, and the box itself breaks because its internal elements are poorly lubricated. Things are a little different with the manual transmission. However, the consequences of mixing the oil will not be any easier.

Can gear oils from different manufacturers be mixed?

Even experienced motorists sometimes believe that by mixing synthetics and mineral oil, you can get a liquid that resembles semi-synthetics in composition. And this is a very big misconception. First of all, when these liquids are mixed, foam will form, and after a couple of days of driving, sediment will appear. It was talked about before. After the car has traveled thousands of kilometers, the oil in the gearbox will become thick and clog oil channels and other openings. Further, the extrusion of the seals may occur.

Whatever information sounds from different sources, it is important to remember that when mixing gear oils from several manufacturers, you can get extremely negative consequences for the operation of the box, up to its complete failure.

But, after all, there is no high operating temperature in the box, which is when the motor is running. But the gearbox is stuffed with high-precision electronics (especially on the machine) and such a mixture of different oils will easily disable it. The only option when you can mix several lubricants under different names is in an emergency on the road. And even if such a case occurs, it is imperative to fill in liquids with the same marking. And, as soon as the car successfully arrives at its destination, you will have to drain the mixed lubricants, flush the box, and fill in a new fluid recommended for use by the vehicle manufacturer.

What will happen if you do not change the oil in the box ?! Not to look nervous)))
