Surely you already know that the engine is the heart of the car, so it should be given due attention. Motorists try to fill the engine of the best quality, violation of this requirement can lead to disastrous consequences. It's time to decide on the choice of oil, taking into account some characteristics and indicators.
No matter how many motorists argue about the advantages of synthetic, semi-synthetic or mineral oil, the choice always remains with the owner of the car. But at the same time, a number of serious points should be taken into account. The first step is to find out the manufacturer's recommendations. Carefully study the service book, it should indicate which oil the manufacturer recommends specifically for this car. If you bought a used car or without a book, you can get information from the official representatives of the brand.
It's all about the chemical composition of engine oils and the properties of additives added by the manufacturer. We can say that oils contain a different set of additives, therefore, they are designed for different operating conditions and engines. The wrong selection of engine oil, at best, will increase fuel consumption and reduce engine power, at worst - it will bring the situation closer to engine overhaul.
Now it is worth assessing whether the previous choice of oil was correct, that is, how high-quality and suitable oil was previously poured into the engine. If you bought a car hand-held, ask the previous owner for this information. If he does not want to tell or does not remember, then you will face additional costs. You will have to thoroughly flush the engine before changing the oil again.
Make a list of oils from different manufacturers and brands that are specific to your iron horse. Among them, you should look for oils that have been certified by the manufacturer, such information can be found on the label. Now it's time to look at viscosity. If mineral oil has been poured into the engine of a car for several years, microcracks that form in the gasket are filled with deposits. The golden mean is semisynthetics, which are obtained from mineral oil by hydrocracking. The advantage of such oil is not only in price, but also in the fact that the transition from mineral oil to semi-synthetics is not so critical.
Motor oils are divided into summer viscosity grades (20, 30, 40, 50, 60) and winter (0W, 5W, 10W, 15W, 20W). The first figure shows the dynamic viscosity at subzero temperatures (at which start is guaranteed). The second number indicates dynamic and kinematic viscosity at 100-150 degrees in summer. Oil viscosity with an index of 50 or 60 is designed for powerful engines and engines that have a mileage of over 100,000 kilometers. Synthetic oil in such an engine will flow through seals and gaskets.
