The engine of the car is the main part of it.Besides, it's not that cheap. Correct and timely care for him can save the driver from most troubles. Engine oil - this is just the thing that should not be saved. The car market is represented by a wide range of oils, but which engine oil is good and which one is better to choose depends on many factors, including the engine itself.
All types of oils are divided by their composition into threecategories - synthetic, semi-synthetic and mineral. To choose the composition of the oil for the car, it is always necessary to be guided by the recommendations of the manufacturer, pay attention to the degree of engine wear and its operating conditions.
Rating of motor oils by popularity can be made as follows:
Which brand to choose is everyone’s business, but it’s worth remembering that a well-known brand does not always guarantee quality.
Важным критерием для всех моторных масел является viscosity. The thicker the oil, the easier it will be to start the engine in the cold season. The viscosity of the oil are summer, winter and all-season. Popular all-season motor oil. It is marked with two numbers and a letter - 10W-40. If we subtract 35 from 10, we get the minimum temperature for using in winter. The second number - 40 - indicates the maximum summer index. The letter W means that this type can be used both in summer and in winter. All-season oil is not inferior in quality to seasonal oil, and if you make a viscosity rating of engine oils, all-season oil will come first.
This is the best motor oil. It is created by the synthesis of chemicals, so initially all positive qualities can be laid into it. Unlike its analogs, synthetics:
"Synthetics" - the most expensive type of engine oil,However, not all suitable. Some substances in its composition have a negative effect on engine parts. Synthetic oil fits more new car brands. It is necessary to choose it when the motor is working under intense conditions. Therefore, the consumer rating of synthetic motor oils is not so high.
This species combines the properties of mineral(50-70%) and synthetic oil (50-30%). Semi-synthetic engine oils are the most popular and common among car owners. Everything is explained by the relatively low price and good properties of the product. Semisynthetics are great for countries with moderate weather conditions. Demand is made by the brands ZIC A +, Esso Ultra, Mobil Super, TSL, which have good antioxidizing, washing and protective characteristics.
The simplest motor oil that turns outas a result of oil refining. It is used mainly on cars of old brands, as well as for engines with low loads. Oil is suitable for all types of engines. It differs in low cost, but, unfortunately, does not possess those qualities that the previous two types have.
To improve properties in mineral oilsadd different additives that help to cope with corrosion and increase engine durability. However, these additives are quickly destroyed, therefore, the service life of mineral oils is low.
The best motor oil can be considered the one thatCarefully looks after the engine of the car and increases its wear resistance. It does not have to be synthetic, because many engines "synthetic" is not suitable.
The best motor oil is the one that is bought in a specialty store and that has a certificate of conformity. The lot number on the package must match the certificate.
The second important point - oil service interval. In other words, how often you have to change it.
It does not matter what type of oil will be, to payattention when buying should be on its density (the smaller it is, the less viscous oil), flash point and alkaline acid number. The latter figure determines the appearance of oxidation during operation.
Any motor oil should perform functions such as:
All motor oils have approximatelythe same performance properties. Differences - only in price. If there are no problems with the engine, you should choose synthetic and semi-synthetic oils. If the engine is too old and worn out - it is more suitable mineral oil, which will provide a dense and thick lubricant.
Undoubtedly, to top the engine oil ratingsynthetics. Synthetic oils can be considered ideal, making an amendment only to the fact that this type is not suitable for everyone. However, knowing only the type of oil when choosing a product is not enough.
It is also important to pay attention to:
In our time in the automotive markets appearsmore and more new motor oil brands. One cannot say, for example, that the Shell brand is equally suitable for all types of engines. Following the adage, you need to keep in mind: not all is gold that glitters. Therefore, the rating of motor oils - this is just a marketing ploy in order to attract a buyer. Every oil is good when coping with its functions!
