Question from the reader:
« Hello. Please tell me what normal oil consumption for not a new engine. A foreign car mileage about 180,000 kilometers. Through every thousand add almost 300 grams! Does it seem to me not normally? Thanks in advance for the answer»
To be honest, I already talked a little about the flow rate of the oil. But today I want to talk about a normal amount. Engine internal combustionWhatever he was perfect, still a little spending oil - so what is the normal value ...... ..
Conditionally, I want to divide the engines: - It is an ordinary gasoline, turbocharged gasoline and diesel, as a rule, they are also turbocharged.
One golden Rule – normal fuel consumption is considered not by car, but by fuel consumption. That is, 100 or 1000 spent liters. Typically, a value is equal to 100 liters.
Normal gasoline engine
For new gasoline engines - Normal oil consumption is considered to be 0.005 - 0.025% per 100 liters. That is, with an average mileage of 1000 kilometers, normal oil consumption will be 5 - 25 grams.
For normally worn engines - normal oil consumption is 0.025 - 0.1%, that is, 1000 km will need to fill 25 - 100 grams of engine oil.
For worn engines on the verge of repair - oil consumption 0.4 - 0.6% per 100 liters of fuel. This is 400 - 600 grams per 100 liters. Critical mark of 0.8% - 800 grams of oil per 100 liters.
In turbocharged engines, the normal oil consumption is slightly higher than that of ordinary atmospheric.
For a new engine - normal consumption may well be 80 grams per 100 liters. That is, 1000 kilometers add 80 grams, 10,000 km - about 800 grams already
For worn turbocharged engines - here the guys can reach two liters. And if the turbine is faulty, then the flow can be even more. Therefore, if your car spends more than two liters, then you need to be diagnosed and necessary to repair.
The flow of diesel engine almost coincides with the turbocharged engine. Normal oil consumption is about 300 - 500 grams of oil by 10,000 kilometers. If the flow exceeds 2 liters, then you need to go to the service.
That's all. Your 300 grams per 1000 kilometers are definitely a lot, go to the car service while.
In the section on the question where to find norms and what frequency to replace Tosol? Posted by the author Iaisia \u200b\u200bLukanina The best answer is to reduce the risk of engine overheating to a minimum, you need to carefully monitor the health of all elements of the cooling system, to carry out prevention and technical inspection, maintain the required level of coolant and eliminate its leaks in a timely manner. With frequency once every two years or every 50 thousand km of mileage should be replaced by Tosol. When replacing Tosola, it is desirable to clean the cooling system from rust, scale and other contaminants using special means for washing.

Try the instruction manual or service book, try to read, there everyone should be written there.
Answer from Eternal student 2007.[master]
there are recommendations for manufacturers - replacement every 3 years. I think the cargo is also no more, since on average for 3 years, Tosol loses the bulk of its useful properties. .

Answer from AVL[guru]
The norm of life is once every 3 years.
Answer from Alexey Baranov[guru]
Some antifreeze are withstanding 5 years of operation and 100-250 thousand km of mileage. The shelf life and the frequency of fluid replacement are usually indicated on the package. And yet, in the process of operation, the coolant gradually loses its properties: due to the triggering of additives and reduce alkalinity, aggressiveness increases to rubber and metals, foaming increases.
Every car enthusiast knows for sure that for normal work The engine in its car must maintain the required lubrication level. During operation, the oil naturally is consumed and it is required to top up. The question arises, what oil consumption in the engine is considered normal?
This article we are talking about this, the reasons for the consumption of lubricant material for the most common engines will be described, recommendations will also be given to competent lubricant control in the motor.
Factors affecting increased oil consumption
Increased lubrication consumption is alarming call for any car owner. Usually, big flow The oil in the engine is present in cars with a large mileage. This indicator needs to periodically monitor, because the lack of oil can cause expensive repairs.
Oil flow rate consists of a set of following factors:
- Age of motor and his specifications . This also includes timely vehicles, the weather conditions under which it was operated, etc.;
- Engagement type. The normal oil consumption of petrol, diesel and turbocharged motors is significantly different and this aspect is simply necessary;
- The values \u200b\u200bof the quality of lubricating material play a huge role.. The viscosity of the oil is one of the main criteria for consumption assessment.
It is worth noting that excessive amount GSM in the engine also increases its consumption. Normated level indicator lubricant It can prevent expensive repair and protect against unnecessary cash spending.
The vehicle can be operated in different conditions (for example, frequent downtime in traffic jams, or on the contrary, movement through country tracks) that affect the correctness of consumption information. The generally accepted indicator of the measurement of the oil consumption in the engine is the ratio of the amount of grease spent 100 liters of fuel.
Indicators of normal oil consumption for different types of engines
As described earlier, it is worth paying special attention Type of engine of your car. Consumption of oil u. different motors directly depends on their device. Below will be the numbers of a normal flow for each type of motor.
Petrol power unit
On the road transportreleased from the conveyor recently, the normal oil consumption is considered an indicator not exceeding 2.5 ml / 100 liters of fuel. It is worth noting that when running a new car, this indicator can be significantly larger, as the new details have not yet been completely launched to each other.
Permissible for cars used, the indicator is equal 100 g per 100 liters of fuel. Such oil consumption is characteristic of cars with minor mileage and in good technical condition.
Increased oil consumption 0.5 l per 100 liters of fuel is considered critical. With such a consumption of lubrication or higher, the engine can simply jam on the go, so with such indicators it is recommended to visit the nearest item of technical inspection.
Diesel power aggregate
Normal fuel consumption for diesel engines is at 300-500 g / 100 liters. Critical flow rate for this type of motor is a consumption equal to 2000 g / 100 liters. IN diesel engine There is always an increased pressure that affects oil costs. Very often, diesel engines are used in construction equipment and truckswhich constantly transport heavy loads. All these additional power costs also increase the consumption of lubricant to a large extent.
Turbated force aggregate
It is worth saying that more and more new engines with turbines have recently appear. The market contains both gasoline power units with turbine and modern turbo diesel engines. The number of turbines can also reach 3rd pieces on one motor.
These power units have tremendous power with perfectly small sizes. It follows the fact that oil consumption directly depends on the power of the motor, so these aggregates are subject to the largest lubricant spending.
Even new turbocked motor It has a flow rate of about 80 g of oil per 1000 liters. For the full work of the turbine itself, a lubricant is required, and if there are several turbines, the costs of the fuel and fuel supply will be much more significant.
And so, an oil flow rate of 1 liter per 1000 km or 100 liters of fuel for conventional Engine It is a critical norm, and for 2 other varieties of engines, the critical indicator will be 2 l / 1000 km or 100 liters of fuel.
Causes of overestimated waste It can be in a contaminated oil filter, it is also necessary to monitor and be sure to install a new oil change.
Why is the overrun of lubricant?
Oil inside car Engine It can be spent both in a natural way and for a number of the following reasons:
- Banal Oil Transfusion in Engine. Increased volume of lubricant contributes to the fact that the oil pushes itself through the openings inside the engine. The oil simply disappears through the ventilation system outside and requires further topping;
- Acquisition of the cheapest lubricant. Poor-quality oil has minimal viscosity and more quickly evaporates, compared with more expensive analogues;
- Excessive loads on the power unit. Too active driving manner contributes to an increase in oil consumption, also on this indicator may affect the landscape of the terrain (mountain, flat and so on);
- Temperature ambient . The increase in temperature is directly proportional to the increase in the consumption of lubricant;
- Physical losses. Usually they are associated with malfunction oil filterBut may be caused by a disruption of the tightness of the motor itself. Very often fails with a gasket between the cylinder head and the engine housing, they can also simply loosen the bolts.
Do not forget that the regular replacement of oil should be made at least 1 times in 10,000 km of run. Such recommendations usually gives a car manufacturer, but in reality, the oil is better changed much more often. It is believed that no more than 8 thousand km from replacement should be under the replacement, and the vehicles with high power this procedure is advised to carry out every 5 thousand km.
On road transport with mileage you can additionally apply various additives that help reduce the consumption of lubricant material. There are many engines on the modern automotive market, which because of their constructive features Begin "there is" oil in the first year of operation.
What kind of components and parts of the engine affect the increased lubrication consumption?
Liquid inside the engine can lean out or evaporate. As a rule, evaporation occurs on the surface of overheated parts and mechanisms. Next, we describe the main signs of incorrect work of the engine parts that can affect the "Jort" oil:
- The main block of cylinders. Often, the gasket begins to flow between the block and the head of the cylinders. The problem can be revealed by a visual way;
- Crankshaft . Similarly to the case described above, the glands can flow due to strong wear. You can detect the problem by breaking the motor. Selns B. this case We'll have to replace new;
- Oil cleaning filter. It can clog or just be fastened. The problem is easy to determine visually and replace this unit to the new one;
- Gas distribution valves. Could fail the engineering caps due to overheating. Oil will start seeping into the mechanism of timing. The problem is eliminated by replacing rubber caps;
- Masonry rings. Wearing these rings on pistons are very frame problem. Of exhaust pipe Begins to go bluish smoke from oil evaporation. Correct the situation can be replaced by rings;
- Malfunction of cylinders. Often, in them, under the action of high temperatures, zadira are formed and excessive wear. The oil is literally absorbed into these microcracks, causing excessive lubrication consumption. The problem is sometimes possible to solve the replacement of piston and oil-challenged rings, but boring or grinding of the cylinders themselves may be required;
- Lubrication turbine. The turbocharger constantly injected the air, because of this, he constantly heats up. He also requires lubricant in the process of work. The size of the turbines can be the most different, so you need to take into account the total volume of oil poured into the engine.
Conclusion
This text covered the most significant moments relating to the normal consumption of oil on road transport. A normal consumption was described, which should be each type of engine, and the reasons for which these unnecessary spending appear are described.
Follow constantly control the lubrication level in the engine of his car. It should not be allowed both its shortages and an excess equally. In any case, before use vehicle It is worth carefully learning the instructions for its operation. It is also worth useing fuel and lubricating fluids that the manufacturer of the car recommends. In this case, the risks will be minimized.
It should be remembered that the consumption of oil on road transport with decent mileage is always much larger, therefore, with the cost of lubricant more than 500 grams per 100 liters of gasoline or a thousand kilometers, you should contact the service center and carry out the entire engine check.
Motor oil consumption Depends on the amount that burns in the engine. It can speak either about its poor quality (the lubricant then excessively burns out), or on the engine malfunction (leakage occurs, most often through the valve glands and oil-chained rings). Everything will depend on specific numbers and additional symptoms that can manifest themselves when the lubricating fluid is fused.
How the oil consumption is calculated in the engine
To determine the norm, the magnitude of the mileage is taken into account, namely the flow rate of the fuel resource. Such an indicator is more accurate than the distance traveled, because when you are standing in traffic jams, the oil is even more depleted, and the odometer does not change its value.
The oil consumption in the engine is customary to count on its volume spent on incineration of 100 liters of fuel.
To find out the oil flow rate in your car's engine, you need to use the calculated formula and calculator or use this online form. It implies the calculation of the permissible amount of oil on the passer according to the type of engine, the volume of the working oil and the amount of consumable fuel taking into account the state piston group.
Calculated oil consumption formulas
Common the actual oil consumption on the ugar per cycle of its work (from replacement to replacement) can be calculated by the formula:
Qy \u003d σq + (qz-ql),
Where σq is the oil, valued during the cycle (between that); Qz - filled with refueling; QCL is merged when replacing.
And here consumption of flooded oil in liters per 100 liters of fuel Determine:
MZ \u003d V / (P * k),
Where V is the capacity of the engine lubrication system; P - consumable fuel K - coefficient taking into account the wear of the piston group (K - for diesel car 1.25; gasoline 1,15; Turbo 1,3).
Oil consumption rates increase to 20% for cars after overhaul And operating for more than 5 years.
Motor oil consumption rate on avgar
For passenger house Vehicles by a normal ugar indicator is the consumption of 0.005 - 0.025% per 100 liters of fuel, which is approximately 5 to 25 grams of oil per 1 thousand km. IN worn engine It can be achieved up to 0.1% and 100 grams. per 1000 km respectively. Well, and if the car works at the limit or has a turbocharged or diesel unit, then such a rule will be even more.
For freight Long-term oil flow rate of 0.3 - 0.4% of fuel consumption. The calculated formula uses the amount of bedrid fuel and a valued oil during this period. But this calculation of the oil consumption, alleged Scania automaker, is relevant only for heavy cars with large Engine. Calculations of the consumption of lubricant in passenger carsAs with diesel and gasoline engines, has a somewhat different look.
Motor oil consumption rate by 100 liters. Fuel for passenger cars
For carburetor cars VAZ norm is considered consumption from 0.3 to 0.4 liters. 100l fuel.
The gasoline engine operating at the limit of its capabilities can consume from 0.4 to 0.6%, at 100 liters. Completed fuel, which is approximately 400 - 600 grams of engine oil per 1000 km of mileage. With diesel, exactly the same situation - the lubricant consumption by the engine increases by 0.5%. But if these are forced turbodiesels with two turbines, then the flow can reach up to 3% of the volume of oil poured into the engine.
Keep in mind that massel consumption standards significantly increase for cars after major repairs and operating more than five years.
The average engine oil consumed by the engine after a run of 150 thousand km is 0.35 - 0.55 liters.
Oil flow rate method
Oil level on Schu
The definition of the actual value of the proportion of motor oil on the avgar is carried out by mileage 200-300 km. The car during the control arrival must be technically correct. The oil level in the crankcase should be between the "MAX" and "MIN" labels of the engine. Before the control mileage, heat the engine, the oil temperature should be 80-85 ° C. Drain oil produced on a flat site. From the pallet it should be flushing for 15 minutes. For the accuracy of the result, it is desirable to define not the volume, namely the weight as the amount of lubrication remaining in the filter can only be considered to weighing it.
How to use the calculator
One of the main roles in this calculation plays the volume of combustion fuel and the volume of the working oil, as well as the type of engine. It is precisely regarding this volume and the specifics of the work carried out a specific oil consumption.
To calculate the specific oil consumption in the engine, such data is required:
- In the field "Fuel" - enter the average fuel consumption in liters, 1`000 km. mileage (default and based on the calculated formulas are 100 liters);
- In the field "Oil" - the volume of oil that is regulated by the manufacturer as necessary when pouring;
- Select the engine type and check if the machine is operated for more than 5 years
- Click "Calculate".
Note that the results, calculator calculation permissible norm Motor oil flows are a common case for some engines (alleged specific design) may be inaccurate, and need to be adjusted.
Such a calculated calculator can be an indispensable assistant to calculate the rate of consumption. lubricants Designed for operational accounting of the specific consumption of engine oil in justifying the need for them. After all, if not all, then many motorists are quite alarming relate to oil consumption in the engine. This service will show whether you are placed in nominal values. If not, then you will have an objective reason to look for causes and possible malfunctions.
What is the result
That is, if the engine is in order, it almost does not take oil, and you will not need to top up until the next replacement. Its level will be in permissible boundaries on the measuring probe (within the Ming / Max marks.). But there are cases where the manufacturer specifies the cost of consumption for a specific power aggregate (Some), then his tank is considered natural and is not a malfunction, but it does not exceed 1-2 glasses from replacement before replacement.
It is important to understand that the intensive engine works, the more the oil burns in it. So, for example, the greater the number of revolutions, the more the oil will remain in the engine cylinders of the car. Although you should not forget not only about the mode of operation of the engine, but also its design. And should not neglect tolerances motor oils and pour fuel and lubricants of dubious quality.
