Viscosity (SAE)

SAE oil viscosity ratings.

This parameter is key when choosing gear oil for a specific car: viscosity requirements are usually directly indicated in the technical documentation, and you should choose in accordance with it.

In most modern oils, viscosity is indicated by two numbers — for example, 75W-80. The first number, with the W index, describes the low-temperature viscosity — at what temperature the oil thickens so much that it can damage transmission components. You need to pay attention to this number if you plan to operate the car in winter: for example, for a climate with winter temperatures down to -30 °C, brands with values \u200b\u200bnot higher than 75W are recommended. To translate numbers into specific temperature values, there are special tables.

The second number describes the high temperature viscosity, in working order; this is the main performance indicator that determines compatibility with the engine. At the same time, only one digit can be indicated in the characteristics — “winter”; this means that the high temperature viscosity of the oil is the same. However, "purely winter" and "purely summer" oils are not always interchangeable, this, again, should be clarified according to the documentation for the car.

Oils with the following SAE standards are now on the market: 10w, 30w, 50w, 75w, 80w, 90w, 10w-30, 10w-40, 75w-80, 75w-85, 75w-90, 75w-140, 80w-85, 80w-90, 80w-140, 85w-90, 85w-140, SAE 90, SAE 140

It is also worth considering that some brands of oils (in particular, for agricultural machinery) can be used both as transmission and motor oils. In such grades, viscosity can be indicated according to the rules of motor oils (these rules are different). One of the signs of such oils is the low "winter" viscosity indicated in the characteristics (well below 70W).

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.
