Do I need to change the oil in the gearbox? Although carbon deposits do not form in the gearbox, metal dust from abraded gears can harm the mechanism here. In order to prevent damage to the transmission and avoid costly repairs, you need to know how to change the oil correctly.
When is the time to change the oil? The answer to this question depends on the brand of machine and the type of oil used. As a rule, these things are interconnected. So, for classics of domestic production and some trucks, mineral oil is used. This is the most cost effective lubricant option. Semi-synthetic oil is used for both VAZ front-wheel drive cars and budget foreign cars. Its price is higher, but it has the best value for money. Synthetic oil is used, as a rule, in automatic transmissions and in all-wheel drive foreign cars with a manual transmission. It is a product of modern technologies: fully purified, with a whole range of additives, with a complete protection program. The replacement cost is the highest. Especially for automatic transmissions, because the volume of oil used in them is several times greater than in mechanical ones. Mineral oil quickly loses its properties and is difficult to purify. Therefore, its replacement is desirable after 30-40 thousand km. The semi-synthetic already contains special anti-corrosion additives that help the gears withstand wear. Therefore, it is changed after 40-50 thousand km. Synthetic oil in mechanics works without replacement up to 70 thousand km, and in automation it is necessary to change it earlier - after 50 thousand. In addition, the replacement period strongly depends on the operating conditions. If you are driving not on asphalt, but on sand or mud, slippery roads or slipping in a snowdrift, the fluid in the vending machine can quickly become unusable. How exactly should you carry out the procedure for changing the oil? The easiest advice is to go to a service that specializes in your car make. If this option is undesirable for some reason, then you need to stock up on the necessary keys and a container where the old oil will be drained. The procedure is carried out immediately after the trip, while the oil is still warmed up. With this method, the oil does not completely change, because about half does not flow out of the crankcase, which means it will continue to negatively affect the gearbox assemblies. And saving on service can result in the need to repair the box. The scope of service can vary significantly depending on the model of the car and the automatic transmission device. Replacing or flushing the filter, dismantling the pallet, the need for a lift - the list of procedures can be very different.
