Each car owner has to maintain his own “horse”: to timely replace the worn out spare parts and in every possible way monitor the condition of the most important car systems. As a rule, an attentive attitude of a motorist to his car is rewarded handsomely, since in this case it is often possible to avoid expensive repairs and extend the life of the main units. The efficient car owner is concerned about any issues regarding his car, first of all, this is the maintenance of the main power mechanism. the engine. A diligent motorist is always worried about the choice of engine oil and the timing of its replacement. Doubts about unconditional trust in the manufacturer, which governs one or another replacement rate, may swarm in his head. And this is understandable. who wants to repair a failed motor, only because they changed the oil at the wrong time.
In this article we will talk about the frequency of changing the oil in the engine. You will learn how to calculate the estimated time for replacing engine oil, and what factors can affect its life.
Calculation of the optimal engine oil change interval for your car
To correctly calculate the optimal engine oil change interval specifically for your car, adhere to the following criteria:
- In the car manual, we find the recommended service interval from the manufacturer;
- We determine the factors affecting the wear of engine oil, specifically your situation;
- We reduce the engine oil replacement rate regulated by the manufacturer to a certain point, depending on factors of “difficult operating conditions”.
- Change the oil according to the selected coefficient.
Oil manufacturer recommendations
The frequency of changing the oil and filters, called the beautiful name “Service Interval”, is nothing but the recommendations of the car manufacturer. It is calculated on the basis of parameters such as fuel and engine oil quality, car class, air pollution, regional terrain features, operation mode, etc. over, the average indicator is taken for all aspects for a particular car model. Something like average temperature throughout the ward.
The average interval, as a rule, is indicated in kilometers and the amount of time (for example, in the form of a recommendation to change the oil every 20 thousand kilometers or at least once a year). All other parameters are considered by default. For example, if you take a sports convertible, you can understand that the manufacturer, when issuing his verdict on the replacement rate, is unlikely to assume that the car will stand idle every day in traffic. If we consider a golf class car, it becomes clear that the car owner does not drive on the highway at a speed of 190-210 km / h, even if the engine’s power allows.
Regional features are more complicated. Certain car models are initially designed for specific car markets, for other cars manufacturers have recently begun to calculate a differentiated service interval, depending on the country where these cars are sold.
Should you trust the oil change service interval?
The era of cars with perpetual motion machines is far behind, so motorists need to get used to the idea that it has long been unprofitable for automakers to produce cars that have not broken for decades, as it is necessary to somehow sponsor their developed infrastructures and also encourage consumers to buy new cars.
Therefore, when calculating the service interval for replacing engine oil, the developer does not think at all about engine longevity. It is important for him how he will work the first period of the factory guarantee, and there at least “grass does not grow.” over, the manufacturer, on the contrary, is profitable if, at the end of the warranty, the engine fails and the unlucky consumer has to visit the company’s service center more than once or, in general, think about buying a new car. So, we can conclude that the service interval is a marketing move to attract customers and the longer it is, the more attractive.
For severe Russian conditions, the regulated engine oil change rate is not at all suitable. Therefore, see for yourself and calculate an individual oil change ratio, according to our evaluation scheme for all parameters.
Factors Affecting Engine Oil Life
Unfortunately, giving universal advice to all motorists is not possible. In all cases, an individual approach is needed. See for yourself, the recommended engine oil replacement period for the driver of a new foreign car will not be suitable for the owner of an old Lada. As well as a motorist who loves to drive along the highway, compared with a person driving only once a week in his car and not exceeding the mark of 60 km / h.
Therefore, in order to correctly calculate the optimal time for replacing engine oil, you need to compare several factors by which you can determine the degree of wear. Of the main ones, this is the season of the year, operation mode, quality of fuel and consumables. Some car manufacturers and engine oil developers give various recommendations on the frequency of engine oil changes, depending on the operating conditions. Maybe you have heard such a definition as “harsh operating conditions” under which oil changes should be made more often? Without particularly going into the physicochemical processes occurring in the engine, one can distinguish the main operating modes that are the most “difficult” for the engine and significantly reduce the life of the engine oil. Let’s reveal this concept and outline the main factors affecting engine oil wear.

- The technical age of the car and the state of its engine;
If your car just got off the assembly line, then with the start of its operation the engine will go to the break-in stage. In this case, you need to use the technical manual, where you will find the regulated engine oil change rate. At the first stages, be sure to observe this particular replacement interval recommended by the manufacturer. Do not forget that the engine break-in stage has a direct effect on its further service life. In this time interval from 5000 to 7000 km, try to avoid aggressive driving style, and as a result, engine overheating. After break-in, the oil should be replaced and in the future only high-quality grease should be purchased from trusted manufacturers. Remember that saving on engine oil can adversely affect engine performance, and even more expensive. The motor will thank you for your careful attitude to it and will delight you with measured, stable operation and a long service life.
If you purchased a used used car, then use a different approach to the problem. Firstly, do not listen to the assurances of the previous owner of the car that the car was used rarely, carefully, and underwent regular oil changes. Immediately after the purchase, carry out an operation to change the oil and filter, not forgetting to flush the engine (you don’t know what oil the previous owner used and when was the last time he poured it, maybe he decided to save money before selling the car and filled the vessel with low-quality grease). Also do not be lazy to subject the machine to a thorough diagnosis, especially the engine. After all, it will be short-sighted if you pour expensive synthetics into an engine that delivers suspicious noises and knocks, plus it can be very gluttonous, and this is a guarantee of high oil consumption. If these troubles did not concern you, you were lucky with a used car, the engine of which works “like a clock”, then use the following recommendation for changing the oil: change it more often and watch for the degree of pollution. In the future, try to increase the replacement time, but only if you use high-quality engine oil.
- Frequency of car use;
There is a common misconception among motorists that if you operate the car as little as possible, it will last much longer than what it drives every day. This is actually not the case. A motor that is started once a week, or, in general, is not turned on in winter, requires a more careful attitude, a more frequent change of oil. But even if these conditions are met, it does not guarantee that the hard working colleagues who work every day will live longer. This is due primarily to condensate that forms inside the engine during prolonged shutdowns. When mixed with fuel combustion products, a rather aggressive, corrosive acid is obtained that destroys the motor from the inside. To avoid such problems, you need to regularly and often change the oil. Therefore, it becomes clear that a simple car does not extend the oil change interval and does not extend the life of the engine. From this it follows that it is better not a large but constant mileage than a simple car in the garage.
- Driving style;
If you are a fan of “gazanut” at the intersection or you respect extreme driving on the highway at maximum engine speeds, then be prepared to pay more attention to the motor. At the same time, frequent oil changes will not be enough to make life easier for the engine. You will have to use only high-quality semi-synthetic / synthetic motor oil.
- Seasonal operation period (summer / winter);
You should not forget about the seasonal features of the use of motor oil. For example, before the winter period of time, try pouring “summer” oil, but don’t be surprised then that already at 15º C the car will not start and the starter will crank the engine with great difficulty. We conclude that when changing the oil you need to take into account the climate of your strip.
- Engine oil quality;
The quality of the lubricating fluid directly affects not only the life of the engine, but also the increase in the replacement intervals by half! If you use an inexpensive “mineral water”, then you have to change the oil every 5. 7 thousand km, if you do not spare money for high-quality “synthetics”, then the replacement interval increases from 10 to 15 thousand km. At the time of purchase, be careful that you do not slip a fake under the original packaging.
- Fuel quality.
This, of course, is a separate, headache for all motorists. The quality of our domestic fuel leaves much to be desired. Unfortunately, such gasoline, with an abundance of impurities, has a bad effect on the composition of motor oil. That which does not burn out falls into the oil, which makes it darker and clogs the engine. To avoid such consequences, we fill in gasoline of the corresponding brand specified by the manufacturer and carefully select a good gas station. If you do not adhere to this, then we run the risk of significantly reducing the life of the engine.
- Engine idle during traffic jams
Congestion on roads has an extremely negative effect on the state of engine oil, since during downtime, with the engine turned on, the efficiency of the cooling system is significantly reduced and the oil heats up greatly, losing its useful properties.
- Car load
Constant driving in a loaded car, towing a trailer and cruising on hilly terrain leads to increased engine load, and therefore to premature oxidation and thickening of engine oil.
- Environmental Condition
If you live in rural areas and drive mainly on dirt roads, lifting up pillars of dust, you should be prepared for the fact that motor oil is much earlier contaminated and says goodbye to its original properties. Unfortunately, even asphalt pavements do not guarantee you an extended replacement interval, since they are often dusty. Whether it is in Europe, where the streets are constantly washed, at any time of the year. Hence the overpriced recommendations of the European manufacturer on the norms for changing engine oil, which are designed specifically for such roads.
- Vacuum oil change (express change)
This item deserves a separate article, but a brief thesis can be highlighted from everything. With express replacement, much more oil remains in the engine cylinders than when draining by the conventional method. over, during the operation of the engine, sediment is deposited on the bottom of the oil pan, which is not removed by vacuum. Therefore, do not abuse this method of changing the oil, it is better to alternate it with the traditional method and after the express change, next time service it ahead of schedule.
