Speaking about the main cause of this problem, experts note, first of all, the lack of tightness of the seals and gaskets, which can be easily eliminated by replacing them, although the price of this service may vary depending on the make of the car.
Other reasons for engine oil consumption may include oil viscosity that does not meet the manufacturer's recommendations, worn valve seals, holes in the piston rings or an increased cylinder diameter due to wear.
Also, improper valve adjustment can lead to oil consumption, and the cost of repairs in such cases varies significantly. Experts also emphasize that prolonged engine idling can further aggravate the problem.
The first signs of engine oil consumption can be noticed when you open the engine oil cap. The smell and smoke when opening the cap are a clear sign of the beginning of oil consumption.
