Although car manufacturers often specify an upper limit of up to 1 liter for engine oil consumption, a properly running engine does not require oil to be added from change to change. In this regard stated Alexey Revin, auto expert of Za Rulem magazine.
“Properly designed, high-quality manufactured and properly operated engines do not require oil to be added from change to change. The only thing I would caution is that from change to change, the owner should not drive more than 7.5 thousand kilometers in a mixed driving cycle, and 10,000 kilometers, mainly on highways at moderate speeds,” Revin said. .
According to him, if increased oil consumption is noticed, it either spills on the road or burns. The main causes of leaks include leaks in the crankshaft and camshaft seals, crankcase and valve cover seals, and in rare cases, turbocharger oil drain lines.
Earlier, technical director of the international franchising network of car service centers Fit Service Nikita Rodionov statedA high oil level in a car’s engine is as dangerous as a low level and can be an indicator of various malfunctions in the vehicle.
“Fuel can mix with engine oil. This is possible in diesel engines and direct-injection gasoline engines. This happens, for example, when fuel leaks from a faulty fuel pump. The oil becomes diluted and its properties deteriorate. Pressure increases, gaskets and seals may be squeezed out,” the expert said.
Also in winter, when the driver makes a short trip, it is possible that the engine oil level is high. In this case, the injectors supply too much fuel, which partly ends up in the pan and no longer has time to evaporate.
