The Difference Between Normal and Excessive Engine Oil Consumption

You might be wondering what the difference between Normal and Excessive engine oil consumption is. You may not know if your car is in the “high-end” category or not. If you have a new car, engine oil burning is completely normal. And if your car has only driven 25,000 miles, engine oil burning is perfectly normal. But if you are experiencing this problem, it might be time to check your oil level and change it.


The normal engine oil consumption of your vehicle is different depending on the type of engine, vehicle type, and operating condition. In most cases, oil consumption is measured in g/100 liters of fuel, but it is possible to get lower or higher figures depending on the engine type. In general, the oil consumption of passenger cars is around 2.5 ml per liter of fuel, while the normal oil consumption of used cars is around 100 g/100 litres of fuel.

The amount of oil that your car requires should be checked on a regular basis, and the manufacturer of your vehicle recommends changing it every 5,000 to seven thousand miles. However, some vehicles may consume oil more rapidly than normal, and you should consult your car’s manual for information. Excessive oil consumption can lead to fouled spark plugs, damaged engine parts, and eventually engine failure. In such situations, it is recommended that you get your oil checked by a professional.


Excessive engine oil consumption is when the level of oil in your car dips too low and starts to appear in the bottom part of the probe. This may be a sign of a number of engine problems, including worn out crankshaft seals or valve cover gaskets. If these components are damaged, oil can leak out, causing further damage. To prevent this, check your car’s oil level regularly, especially if it’s been too long since you changed it.

Oil consumption is a common problem for internal combustion engines. While internal combustion engines generally don’t use much oil, excessive oil consumption can cause serious damage to the engine. Excessive oil consumption also contributes to high carbon formation and reduced fuel efficiency. Ultimately, it’s not only bad for the environment, but also can affect your engine’s performance. The following are some solutions to excessive engine oil consumption:


The issue of excessive engine oil consumption has been around for some time now. While it’s perfectly normal for your car’s engine to burn oil, excessive consumption is not. Some car manufacturers define “normal” consumption differently than others. In many cases, an engine can burn more than one quart of oil between oil changes. In such a case, you should consult your car’s owner’s manual for advice. Listed below are some tips to help you reduce engine oil consumption.

You should know that modern passenger cars typically use less than 0.05% of the total fuel consumed. Oil consumption is measured in percentages, so a liter of fuel will consume about $5. 000 kilometers. Older types of cars, stationary engines, and other special operating conditions can cause engine oil consumption to be higher than normal. Excessive engine oil consumption is when the oil consumption exceeds the allowed amount. There are different lubricant mixtures for different car engines. Incorrect mixtures can damage internal engine parts. In addition, low-viscosity oils can damage engine components and lead to excessive oil consumption.


The Specified engine oil consumption for your vehicle is the figure where the level of oil decreases from the top of the probe to the bottom. You can use conventional or synthetic engine oil. Both meet the same requirements and servicing intervals. Other manufacturers may use alternative specifications. It is important to read the specification of your vehicle’s oil. This article will address both types of engine oil. You will also discover how to determine if a product meets your requirements.

The maximum oil consumption for passenger cars is typically 0.05 to 3 dl per 1.000 km. This limit is often much lower for modern cars. In fact, some vehicles consume as little as 0.25% of the specified oil. However, if your vehicle is older or undergoing special operating conditions, its maximum oil consumption may be much higher. The reason for this is that different types of engines need different lubricant blends. If you don’t choose the correct type of lubricant, it may damage internal engine parts.

Manufacturer’s specifications

The standard used by automotive manufacturers to determine how much oil to use in an engine is known as API or the American Petroleum Institute. API was established in March 1919, and it oversees certification of petroleum industry standards in the United States. The ACEA is the European equivalent of API. These specifications are used by automotive manufacturers across the globe. If you’re not sure what type of oil your car requires, check the manual or the manufacturer’s website.

Some people feel that excessive oil consumption is bad for the environment. The problem with using oil in an engine is that there are moving parts and the oil isn’t 100 percent oil-tight. Oil is consumed at a low rate by the moving parts, but at the same time, the oil film on the cylinder surfaces is exposed to high-temperature combustion, burning and vaporizing. Engine oil is then released into the environment with the exhaust gas.

Lighter motor oil

You might have heard that using a lighter motor oil will increase your vehicle’s oil consumption. While this may be true, there are some advantages to using a heavier oil. In cold weather, the lighter oil will reduce friction and lubricate internal engine parts. However, you need to be aware of the risks that come with lighter oil. The lighter motor oil can be more difficult to apply to the piston rings, and may also leak out of the combustion chamber or through gaskets.

A thicker motor oil can cause excessive wear on the engine and lower fuel economy. It also increases the load on the engine, which shortens its life. On the other hand, a thinner oil will cause the engine to last longer. The choice of which type of oil to use depends on the type of vehicle you have and how often you drive it. The recommendation of the manufacturer will depend on your specific vehicle. In general, you should use the oil grade that the manufacturer recommends for your car.

Piston rings

If your piston rings are worn, your engine may run rough or even not start at all. Worn piston rings also mean that combustion oil is slipping past the ring faces, which will cause the engine to burn more oil. Worn valve seals can also contribute to excessive oil consumption. Additionally, if the piston rings are stuck or clogged with heavy deposits, they will not float freely in the cylinder liner and will stick to the piston. This can reduce engine power. Lastly, stuck piston rings can let combustion gases seep into the oil sump, which will contaminate the oil.

The main relationship between piston rings and engine oil consumption is that the piston ring joint clearance is important in regulating compression and lubrication. If the joint clearance is too large, the engine will lose compression and its performance will suffer. In some cases, the second compression ring is also affected, which is the cause of the increased oil consumption. These problems can be solved by replacing the faulty piston rings, but it is important to check the joint clearance first.

Valve seals

Engines depend on a valve stem seal to prevent combustion gases and engine oil from leaking into the main engine area. A defective valve seal can lead to excessive engine oil consumption and breakdown. If you suspect that your valves have bad seals, you can conduct a cold engine test to check for leakage. If you notice oil on the valve headcover, a bad seal is probably to blame. Alternatively, you can contact a trusted auto part manufacturer to find out if your seals need replacing.

High oil consumption indicates bad valve seals. You should regularly check your oil levels using a dipstick. If the oil is low, there may be a leak. You can also observe excessive smoke, which indicates a valve seal problem. Moreover, you should check the oil level with a car’s engine oil gauge to determine the cause of excessive oil consumption. During a test, you can also check if your engine is losing oil or is burning it. If you notice any of these signs, you can take the car to a mechanic for an inspection.

Driving style

Depending on the make and model of your vehicle, you may find that you use more oil than you should. Your driving style also contributes to oil consumption. Driving fast puts extra pressure on your engine’s seals and gaskets. Some of this oil will burn in the combustion chamber. Consequently, a higher RPM means higher oil consumption. However, slowing down a bit can also decrease your oil consumption.

The quality of your fuel also matters. When your vehicle is using poor quality fuel, you can reduce the amount of oil it can hold and cause more stress on the engine oil pump. The viscosity of engine oil is also affected by poor fuel. Changing oil more often can help keep your vehicle running smoothly. Driving style also has a bearing on oil consumption. Drivers who like to drive fast should expect higher oil consumption. To prevent excessive oil consumption, reduce gas pedal pressure and stick to a normal driving style.
