Type
The type is determined by the composition of the oil.
—
Mineral. Oils made from products of petroleum distillation. Such compounds tolerate temperature extremes worse than synthetic ones, which is why they require more frequent replacement and are poorly suited for extreme conditions and high-end transmissions. On the other hand, during normal driving on relatively simple car models, “mineral water” is practically not inferior to “synthetics”, but costs much less.
—
Synthetics. Compositions from components obtained artificially (synthesis). Considered more advanced than mineral oils, oils are produced in this category, including for expensive cars that are demanding on the quality of fuels and lubricants. In addition, “synthetics” do not pollute the system so much, and after draining such oil, it is often not necessary to flush the transmission at all. However, these brands are not cheap.
— Semi-
synthetics. A compromise between the two types described above are oils consisting of both mineral and synthetic components. Such compositions have more advanced characteristics than "mineral water", while they are much cheaper than "synthetics".
Volume
The capacity of the package in which the oil is supplied, in fact, is the amount of oil in the delivery set.
To fully refuel the transmission of a passenger car, it usually takes about 3-4 liters, in trucks this value is noticeably higher (up to several tens of liters). Accordingly, the choice by volume depends on which car the oil is bought for and for what purpose (topping up or a complete replacement). And for service stations, repair shops, auto enterprises, etc. oils are produced in barrels of 60 or
200 (210) L.
Now on the market there are packages of various capacities, among them the most popular:
1 L,
2 L,
4 L,
5 L,
10 L,
20 L,
60 L.
Manufacturers approvals
Manufacturer approvals for the gear oil.
Tolerances are the own standards of major automakers, developed taking into account the technical features of individual car models. If the oil meets the tolerance specified in the documentation for the machine, then it takes into account these technical features and is optimally suited for this model.
