The engine of any car consumes oil. Somewhere this figure is bigger, somewhere less, but the fact remains that all engines eat fat. And cunning car manufacturers have
The consumption of up to one liter of oil for a good 8-10 thousand kilometers is quite legal for modern engines. But if this figure is significantly exceeded by your power unit, then you need to figure out what’s going on. And for this it is not at all necessary to disassemble the engine.
To identify the cause of the increased consumption of engine lubricant, first of all you need to make sure that there is no ordinary leakage. Oil stains on the engine or puddles under the car indicate damage to a seal. These could be crankshaft seals, camshaft seals, leakage under the gasket or sealant, loss of tightness of the plug in the oil sump or oil filter, damage to the oil supply and discharge lines on the turbine. In general, if the dust is in the sealant, it simply needs to be replaced and oil consumption returns to normal.
Oil can also drain if there are problems in the crankcase ventilation system. As a rule, a clogged oil separator causes this problem – this is not only increased oil consumption, but also a problem with intake valves and deposits in the cylinders. Therefore, it is necessary to diagnose this system as well. As well as the valve of the crankcase ventilation system, which is responsible for adjusting the pressure. If it sticks, the oil flies into the cylinders and burns in large quantities.
Old worn engines can eat oil due to wear on the cylinders and pistons, the gap of which can increase significantly over time. In this case, experienced motorists recommend switching to a thicker and viscous oil. However, keep in mind that with a thick lubricant, the engine will start worse at sub-zero temperatures. But we had to beat the oil eater, didn’t we? And if so, then this method works.
Using additives is also an option to beat the engine’s oil hunger. The chemicals will thicken the oil and also soften the rubber seals. And we get profit again.
Coked oil scraper rings also cause an increase in lubricant consumption. In this case, autochemicals come to the rescue, able to clean and free the rings from deposits and restore their mobility. But the method unfortunately does not work in particularly neglected cases.
If the oil burner problem is worn valve stem seals, they will need to be replaced. The procedure is not easy. However, engine overhaul is much more difficult. And more expensive.
Since the entire automotive industry has come to the conclusion that it is not profitable to make reliable cars, car manufacturers reduce the cost of parts as much as possible. So we got shortened pistons and thinner rings with medium elasticity. If such an engine was not properly maintained or often experienced increased thermal stress, the rings lie down and oil combustion begins. There is only one verdict – change the rings.
And of course Her Majesty is a turbine. With increased oil consumption, it is worth looking into the rotor seals. Due to problems in this part, the oil can both go to the piston group, contaminating it as much as possible, and fly away towards the catalytic converter with negative consequences.
With a noticeable increase in oil consumption by your car’s engine, competent diagnosis is required to help develop a strategy for eliminating the oil burner. If your car’s engine is not old and you have used it carefully, the increased appetite is no reason to be discouraged. Maybe everything is not as scary as it seems.
