We select oil for the gearbox
Almost all well-known companies specializing in the production of lubricants offer their customers products of exceptionally high quality, which have proven themselves over the years. In this article, we will try to figure out which particular oil is best for your particular car.
How to choose gearbox oil?
Choosing the right gearbox oil is a tricky process. First of all, you must follow the instructions of the car manufacturer. All the necessary information is available in the manual in the chapter "Lubrication system".
Synthetic transmission fluids are much better than mineral ones in their characteristics, they are great for reliable protection of mechanisms that are under heavy loads. But the price is much higher than the mineral. In case you need to save money, you can use semi-synthetics. But do not forget: in no case should you mix mineral water and synthetics, if necessary, you can only mix liquids with the same marking!
Gearbox fluids from Motul and Castrol Fluids for a manual transmission are classified primarily by viscosity level (SAE), as well as by the level of compliance with the conditions in which the car is operated (APL).
In turn, the SAE classification is divided into three categories:
- winter transmission fluid (70W, 75W, 80W and 85W);
- summer transmission fluid (80W, 85W, 90W, 140W and 250W);
- all-weather transmission fluid (75W-90, 80W-140).
Transmission lubricants from the manufacturer Elf Tranself EP 80W-90 As for the APL classification, it, in turn, is divided into 7 groups, but GL-4 and GL-5 are considered the most common:
- GL-4 is well suited if the gearbox is operated under light loads;
- The GL-5 is designed for exceptionally harsh conditions.
By the way, you can see that, on our roads, the most ordinary operation of a car may well become extremely extreme, since low fuel quality, high dustiness and a long winter significantly accelerate various processes occurring in oil, which means that its lubricating properties are quickly lost.
If we talk about oils used in automatic transmissions, then there are no strictly defined rules for them. Major car manufacturers have formed their own standards for ATF.
But if you are confused or afraid to make a mistake, then there is another correct method for determining. You can always find out which oil to pour into the box at the service station of your car.
Selection of oil by car brand
Manol FWD Getriebeoel and Lukoil 75W-85 TM-4 One of the main and most correct options for choosing a transmission fluid is a thorough study of the instructions for the service and operation of the vehicle, it comes with the car. You just need to find the right item, find out the brand of liquid and purchase it. The correct selection of oil very seriously affects the operation of the car, with the wrong choice, you can easily disable it or fundamentally reduce the life of individual parts and assemblies. As a result, we will try to approach the issue of choosing a transmission fluid extremely seriously. First of all, you should choose from those fluids that the manufacturer recommends.
AvtoVAZ recommends the following oil for a car of its own production:
- OMSKOYL TRANS P (indices 80W-85; GL-4/5);
- VOLNEZ TM4 (indices 80W-90; GL-4);
- gear oil REKSOL T (indices 80W-85; GL-4).
From foreign ones, any one that corresponds to GL-3 or higher is suitable, but in this case it is easy to buy fake oil instead of the original oil in our time. Shell Spirax S5 ATE 75W90 GL4 / 5 oil has proven to be excellent.
