During the operation of a vehicle, its transmission is subjected to increased loads and difficult tests. This leads to wear on important parts and shortens the life of the unit. Manual transmission oil treats moving parts to maintain system performance.
When the oil in a manual transmission changes and how to check
Experts recommend changing the oil in the manual transmission at least after 80-100 thousand kilometers or after 5 years of car operation. If the vehicle is exposed to high loads, it is necessary to change the lubricant after 50-60 thousand km. The exact numbers are indicated in the manual for the specific vehicle model.
However, in some cases, replacement is not carried out during routine maintenance and service, but under other circumstances. Among them:
- Buying a used car. The oil is changed without fail, since there is no exact guarantee that it was updated in accordance with regulatory requirements. Even if the previous owner claims to have regularly serviced the machine, it is best to replenish the lubricant supply.
- Installing a new transmission. The new manual transmission is filled with new oil. At the same time, if the composition was updated according to the regulations, but after a while the box had to be changed, you can reuse it.
- Box service. Often, the transmission unit fails due to lack of maintenance or the use of low-quality oil. Therefore, to prevent such problems, you should fill in a composition that is suitable and recommended by the manufacturer.
- Noise or jerking when shifting gears. The least costly but effective troubleshooting method is refilling with new fluid. In most cases, the method solves the problem and restores the normal operation of the box.
Aggressive machine operation with frequent slippage will expose the transmission components to increased stress and wear. In such a cycle, the oil loses its properties much faster, and the additives begin to foam. As a result, heat dissipation and lubrication performance is lost, and the box wears out. If you notice strange changes when shifting gears, it is imperative to check the condition of the mixture.
Despite the fact that high-quality oils have a resource of 100 thousand km, their properties may not be enough for this period of validity. A shortage of funds provokes accelerated wear and tear of the unit. Therefore, experts advise checking the level every 10-15 thousand kilometers.
Depending on the make and device of the machine, the way of estimating the oil stock may differ. But the universal method involves unscrewing the plug in the pan and then draining a small amount of the mixture. By the shade and consistency of the composition, you can determine its quality - the darker it is, the worse the properties.
The check is carried out after the car is installed on the most even pit or lift. Then you should wait a few minutes for the technical fluids to cool down. If there is a dipstick in the machine, you can use it to check. In the absence of a device, it is necessary to find the filler plug (in most cases it is located on the side) and unscrew it (the oil level must correspond to the lower thread of the control hole). In this case, it is important not to confuse it with the drain plug, which is directed downward.
If there is less liquid or it is not visible at all during an external examination, it will be necessary to restore the supply with a syringe. Also at this stage, you need to check the box crankcase for leaks on the side of the seals (washers and oil seals). If there is any suspicion of wear of the parts, they must be replaced.
When adding oil, it is not difficult to assess the current level - it will begin to flow out of the control hole. After completing the action, wipe the crankcase dry.
TOP of the best oils for manual transmission
There is an extensive range of manual transmission lubricants on the market. When compiling a rating of the best compositions, the following characteristics were taken into account:
- opinion of independent and professional experts;
