Why consume oil cars? Debunking myths and solving doubts

That car consumes oil, you might have said on some occasion. Really, all cars consume oil, and according to the instruction manuals of the greater part of manufacturers, a maximum consumption of up to one litre per 1,000 km is considered normal. In this article we dismantle myths about the oil consumption of the engines, we clarify concepts and respond to the most common questions. Is it normal for my car to consume oil? How can I control its use? do I have engine problems?

All cars consume oil. Why?

It is important to maintain a proper level of oil and regularly check their consumption.

The oil is the blood of your engine. Lubricates pistons, valves, turbochargers. This thin film of oil coats all of the internal components of the engine and allows for less friction between its parts, the proper functioning of the same. It is especially important in the combustion chambers, inside which move the pistons of the car at breakneck speed. Without this lubrication, the heat generated by the contact between the parts of the engine would melt its components among themselves in a matter of seconds. This is what happens when an engine runs out of oil.

averias-motor-3keep in mind that the tolerances of many components are micrometer, so it is vital to a good lubrication. It also ensures that the turbocharger rotate smoothly and efficiently, and lubricates the valve train, whose movement is as fast as the piston. A tiny amount of oil burned in each cycle of explosion of the motor. Even a tiny amount, we should not forget that the cycle of explosion is repeated thousands and thousands of times in the inside of the engine on a daily basis.

how Much oil should I consume a car? What increases with the age of the car?

The pilotamos bike usually are used to monitor frequently their consumption of oil, higher than a car.

As before we have explained to you, a consumption of a maximum of one litre per 1,000 km is considered normal by most manufacturers. But the conduct of each person is a world. If you drive aggressively typically, regimes, or higher, you walk into circuit, a high consumption of oil should not be the symptom of problems. A relaxed driving by highway with a diesel engine results in a very low-energy of oil, to the point that it is unnecessary to pour more oil between maintenance intervals.

The crankcase of a four-cylinder engine – a two liter – and usually houses in its interior between four and six liters of oil. The greater part of official services and workshops, they fill in a little above the level recommended to avoid the consumption of engine oil gets to be dangerous. Let’s be frank, the majority of drivers do not monitor the oil level of their cars.

There are engines with higher oil consumption than others, by definition. An oil consumption moderate is not a symptom of mechanical problems.

If you practice a normal driving and your engine consume a disproportionate amount of oil, yes, you should worry. It is possible that you have a outside leak – for example, drips into the sump – or is a symptom of internal problems in the engine. You can go from retainers valve very worn, to a turbocharger about to say enough is enough, going through a wear and tear the result of high mileage. The engine wears out with the passage of time, and the tolerances between the internal components increase with age.

Audi 100 2.5 TDIhowever, a car well-maintained with a high mileage, not squeezes in cold and use a quality oil can have an oil consumption very low. If your exhaust expels a smoke whitish with a bluish tone and a characteristic smell of “burnt”, that is a sure sign that a mechanical failure is imminent. The engine is sucking down oil like there is a tomorrow. Go to as soon as possible to a workshop and constantly monitors the oil level if you cannot attend at the time or you’re traveling.

How do I check the oil consumption of my car?

It is advisable to monitor the oil level of the car before and after a long trip, or every two weeks. It’s free and just takes a minute.

regularly Reviews the level of oil. To do this, you must place the car on a flat surface, and in cold check that the oil level is between the mark of the minimum and the maximum. In most cars, between the maximum and the minimum there is about a quart difference. If the oil is low, fill with proper oil for your engine. Poured by opening the plug – usually yellow – located on the motor. The cap will usually say “OIL,” and sometimes it has recorded the drawing of an oil can.


What do I do if my car has a engine tired and consumes a lot of oil?

The motors wear out with the passage of kilometers, and at times its consumption of oil you can shoot over a litre/1000 km maximum. If that is the case and not practical driving especially demanding, try using an oil of higher viscosity. For example, if you use a 10W-40, try using a 5W-40. It is an oil more dense, so it will cost you more effort to reach the combustion chamber and burn. In addition, will occupy the space better located in the large internal clearances on your engine.

Due to its unique internal architecture, the oil consumption of the rotary motors is higher than that of a piston engine – not that they are “damaged”.

sell specific oils for engines of a certain age, precisely to ameliorate the high consumption and adequately protect the mechanics. Not to be confused with a oil the long-life. A oil the long-life is simply a synthetic oil long-lasting, which retains its lubricating properties up to 50,000 miles in some cases. That’s not to say that is not consumed: consumed in the same way as other oils and should be monitored consumption usually, as in any vehicle.
