Rating of engine oils - the best synthetic and semi-synthetic oils
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.
Varieties of motor oils
All types of oils in their composition are divided 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 manufacturer's recommendations, pay attention to the degree of wear of the engine and the conditions of its operation.
The rating of motor oils by popularity can be compiled in this way:
- In the first place - expensive brands - Shell, Castrol, Mobil, Esso, Delphi.
- On the second - budget - Aral, Total, Agip, Mannol.
- At the last - domestic producers - "TNK", "Lukoil", "Azmol".
What brand to choose is everyone's business, but it is worth remembering that not always a well-known brand guarantees quality.
An important criterion for all motor oils isviscosity. The thicker the oil, the easier it will be to start the engine in the cold season. According to the viscosity of oil are summer, winter and all-season. Popular all-season motor oil. It is marked with two numbers and the letter - 10W-40. If 10 is subtracted from 35, the minimum temperature of use in winter will be obtained. The second figure - 40 - indicates the maximum summer figure. 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, and if the rating of engine oils is made on viscosity, all-weather will be on the first place.
Synthetic Engine Oil
This is the best motor oil. It is created by the synthesis of chemicals, so initially it can put all the positive qualities. Unlike its synthetics:
- It has more fluidity, resulting in reduced friction and fuel savings.
- Less is amenable to fumes.
- Does not oxidize and does not lose its operational properties.
- Has an extended service life.
Synthetic is the most expensive kind of motor oil,but not all suitable. Some of the substances that make up it negatively affect the engine parts. Synthetic oil is more suitable for new brands of cars. It must be selected when the motor is running under stressful conditions. Therefore, the consumer rating of synthetic motor oils is not so high.
Semisynthetic motor oil
This species combines the properties of mineral(50-70%) and synthetic oil (50-30%). Semisynthetic motor oils are the most popular and popular among car owners. Everything is explained by the relatively low price and good properties of the product. Semisynthetic is excellent for countries with mild weather conditions. Demand is used brands ZIC A +, Esso Ultra, Mobil Super, TSL, which have good antioxidant, detergent and protective characteristics.
Mineral motor oils
The simplest engine oil that is producedas a result of oil refining. It is used mainly on cars of old brands, as well as for engines with small loads. The oil is suitable for all types of engines. It differs in low cost, but, unfortunately, does not possess the qualities that the previous two types have.
To improve properties in mineral oilsadd different additives that help to cope with corrosion and increase the durability of the engine. However, these additives are rapidly destroyed, therefore, the service life of mineral oils is low.
The best engine oil
The best engine oil is that whichcarefully cares for the engine of the car and increases its durability. It does not have to be synthetic, because many engines "synthetics" are not suitable.
The best motor oil is that which is bought in a specialized store and which has a certificate of conformity. The lot number on the package must match the certificate.
The second important point is the oil service interval. In other words, how often you have to change it.
It is not important what kind of oil will be, to reverseattention when buying should be at its density (the smaller it is, the less viscous the oil), the flash point and the alkaline-acid number. The last parameter determines the appearance of oxidation during operation.
Any motor oil should perform such functions as:
- Protection against wear.
- Cooling of engine parts.
- Lubrication and washing.
All engine oils have approximatelyidentical operational properties. Differences - only in price. If there are no problems with the engine, synthetic and semi-synthetic oils should be chosen. If the engine is too old and worn - it is more suitable mineral oil, which will provide a thick and thick grease.
What should I consider when choosing engine oil?
Undoubtedly, will lead the rating of motor oilssynthetics. Synthetic oils can be considered ideal, making a correction only to the fact that this type is not suitable for everyone. However, to know only the type of oil when choosing a product is not enough.
It is also important to pay attention to:
- Year of car manufacture.
- Year and type of engine.
- Manufacturer's recommendations.If the technical characteristics indicate specific parameters of seasonal oils, then only they need to be bought. In the event of a replacement, serious engine problems may occur.
- Operating conditions - on what roads the car moves, what weather conditions prevail (climate).
- Engine mileage. For example, during the break-in period, experts recommend the use of mineral oils, and for cars with mileage - semi-synthetic or synthetic.
Nowadays in the automotive markets appearsmore and more new brands of motor oils. You can not say, for example, that the Shell brand is equally suitable for all types of engines. Following the proverb, one must keep in mind: not everything is gold that glitters. Therefore, the rating of motor oils is just a marketing move in order to attract a buyer. Any oil is good when it comes to its functions!
