Is the consumption of oil in an engine a factor that points us that there is internal wear that requires us to overhaul the medium term?
Does it consume a new engine oil or not? Well, we will try to clarify doubts that arise among our readers.
There are several reasons why an engine can consume oil, this consumption can be mild, moderate or severe and the impact on other parts or systems of the engine by this consumption will logically be associated with that quantity is that oil consumption engine.
We must remember that one of the main and most important goals of the oil inside the engine is to lubricate, inside the engine we have parts such as the crankshaft, connecting rods, camshafts, valves, pistons, rings and cylinders in constant movement, Due to this the engine is provided with a lubrication system whose mission is to interpose a thin layer of oil between these moving parts in order to protect the engine from severe and accelerated wear.
Oil consumption
When we talk about oil consumption clearly understand that this oil consumed is that the engine burns and burn to this oil reach the combustion chamber, however, must exist or no oil in this chamber when combustion ? Let us recall that an internal combustion engine has 4 phases or times, intake, compression, combustion and exhaust, every time we have the piston either ascending or descending the cylinder, and each movement must exist as in the other components Internal a thin film or layer of oil that provides protection against the friction of the piston and its rings against the cylinder to prevent premature wear thereof, so that each time the piston in its upward stroke on the cylinder reaches its The highest point is spread abundant oil over the entire circumference of the cylinder below the piston, once at its highest point the piston returns down and the rings of oil are responsible for collecting excess oil but at the same time leave a film Very fine so that the rings above this get lubrication and protection have it checked out by a local mechanic.
We are already landing on the subject, the engine in the intake time sucks air (open intake valve and down piston), once this comes to the compression time (valves closed and piston ascending), compress the air and fuel mixture To reach the combustion time (piston at its highest point compressing the mixture of air and fuel), at this point a spark is produced and the mixture is ignited by forcefully pushing the piston down, this combustion will be expensive So that it will have a start and will cover the whole circumference of the cylinder as the piston descends, the temperature that at that moment will burn part of the oil film.

In this way, a new engine always burns oil because it is somewhat adherent to the lubrication system to protect the internal parts, IF AN ENGINE DOES NOT CLEAR OIL MEANS THERE IS NO OIL COVER NEEDED BETWEEN THE PISTON AND THE CYLINDER, WHICH WOULD INDICATE THAT NOT THERE IS LUBRICATION.
One could calculate up as a normal consumption of one liter of oil per 4000 kilometers this depending on the type of engine and the type of oil recommended by the manufacturer, taking into account that many manufacturers seek extended change intervals maintenance that exceeds 20K Kilometers for each oil change should pay special attention to the suggestion of the manufacturer as to the type of oil recommended.
However, the lubricant is not magic, for better quality you use will always be frictions that as progress kilometers traveled provoke internal wear, they wear out, they will cause increasingly greater amount of oil reaches the combustion chamber when this happens In excess the oil begins to form coal deposits in the piston, in the spark plugs, in the valves, even altering the reading of the oxygen sensor and obstructing the catalyst, logically the coal deposits in the valves will cause losses of compression and the same deposits of coal in the pistons will more easily break the oil film adhered to the cylinder causing abrupt and accelerated wear between the piston, rings, and cylinders causing considerable losses of power and a constant celestial smoke exiting the exhaust.
Oxygen sensor, spark plugs or even oil-filled catalysts will result in gas tests that will not be within normal and fully pollutant parameters.
It is important to note that oil consumption can also be caused by the famous valve seals, these seals do not allow the oil to run down the valve stem into the combustion chamber and often cause during startup in the morning see a lot of blue smoke, these valve seals depending on their condition are also a great source of oil consumption.
If you want to know more about valve seals you can also read here-> What are and how to change the valve seals?
Well, there is other factors consumption such as clogged PCV valves and gaskets valve covers or more specific systems depending on the brand of car in which deterioration cause the oil to reach the engine intake and be sucked into the engine , However, these cases are very rare.
