In our time to make any selection without proper training is difficult. On the market there are more and more new players, luring buyers more for less money. Massive advertising campaigns, tough promotion of unknown brands. How not to get lost in such an environment and make the right decision? Even buying a mobile phone involves certain difficulties. But the only phone - in case of an unfortunate choice of not punch a huge hole in the budget. Another thing - a car. Non-expert service and use of substandard materials can turn into a disabled group I just yesterday as a reliable and faster iron horse, and the reverse process may require huge financial investments. I would like to dwell a bit on car oils, as a quality product can be overhauled to postpone indefinitely, and poor quality - to finish off the engine and transmission for several tens of thousands of kilometers, and even faster. In this article, I will not delve into the deep jungle of chemical, pausing only to general recommendations. Today, owners of new cars are on warranty service issues on the choice of lubricants is not there - Dealer Techcenter conducting, as a rule, makes the choice for them, using lubricants recommended by the manufacturer. Global trends are all familiar: saving fuel, reducing harmful emissions, respect for the environment. In this "green" background appear motor oils with low viscosity, which are designed to save fuel by reducing losses due to friction in the engine. Nature they are somewhat spared (relatively small), but the motor - no. The same applies to oils series «Long-Life» with replacement 20 000 - 30 000 km. It's funny, but these solutions into the hands of automakers. The faster "zagnetsya" one car, the faster will buy another one. Fleet of new cars in Moscow is very large. As a rule, people prefer to take a new car for several reasons. Perhaps the most important of which - the absence of a civilized market of used cars. In fact, in today's Russian reality, this choice be right, but in times of crisis the new machine will become less accessible, and global trends are such that in civilized countries, the owner is in no hurry to sell his iron horse right after the warranty period. Please note that in Europe is very large fleet of used vehicles older than 5-7, and even 10 years. Even in the highly successful U.S. percentage of vehicles older than 3 years is impressive. Sooner or later Russia will be the same, change the very mentality and attitude to travel, it's only a matter of time. After the end of the warranty period, you can optimize maintenance costs and try to extend the life of the car, already withdrawn from childhood. In such a difficult matter, as the prolongation of life, not the least is the right choice of motor oil. In a modern car there are different liquids, but that's motor oil works in the toughest conditions. The modern market offers a variety of oil price categories. After reading the recommendations on the applicability of lubricants for your model, you may find that you can buy a canister for 250 rubles. As you can - for 1500 rubles. If there is no difference, why pay more? But there is a difference, believe me. First, the manufacturer's instructions. I think no one doubts that better - Shell and Lukoil. If the first company engaged in oil and lubricants from the beginning of last century, LUKoil has appeared in the era of the original accumulation of capital in Russia, ie, very recently. If Shell - the official supplier of oil for Ferrari, then Lukoil similar client can not boast. Generally, from personal experience and reviews repairmen tend not to trust until native lubricating products. Gasoline, diesel oil and even more so, we have a very poor quality, and lubricants, I think, left them close. API (American petroleum Institute, American Institute of Fuel) is conducting tests of motor oils. Venerable import concerns have been approved API, and confirmation of quality. With domestic product while not all that happy. Most of them did not pass the relevant tests and does not have a certificate issued by API. Classes in the API is installed, usually, by analogy with foreign oils, which have in their composition similar additive package that is not a sufficient criterion for confirming the performance characteristics. Another important point - the viscosity of multigrade engine oils. Only now they are available. The most important winter and summer characteristics shared in by the letter W, which means Winter, ie winter. The first number - it's pumpability in cold conditions (at low temperatures), ie, characteristic of winter. Rather arbitrary, but for simplicity we can use the following rule: from number 35 to take the first number of markings. Example: take the oil with a viscosity of 15W40. 35-15 = 20. That is, this oil can be used at temperature not lower than-20oC. What happens if you ignore this recommendation? Of course there are some safety margin, but particularly count on it not worth it. May happen: the oil filter will not miss is unable to flow oil, and it will simply break (it happens often enough). Perhaps both: maslopriemnik suck all the thickened substance around itself, and the oil pump starts to drive air through the system. If time does not switch off the engine, it will end overhaul. The number following the letter W indirectly reported in cSt viscosity at high temperatures, ie, it is already "old" response. These roughly as follows: the number "40" corresponds to 15 centistokes. Generally, 40 - the most common viscosity for engine oils. It is this value ensures a more or less stable system pressure. There are now already I have mentioned energy saving oil viscosity index "30" and even "20"! Personally, I am so into his car would hesitate to fill. There are oils with high viscosity, they have excellent lubricity characteristics and create a stable oil wedge in hydrodynamic bearings, lubrication systems. Interestingly, the experts say about this? Specialists NAMI-Chim says: "With increasing viscosity of 15 (5W40) to 20 (5W50) centistokes primarily stabilize the pressure in the system. Consequently, the lubricant will be supplied to the friction pairs in proper quantity, keeping in the gaps of the mating parts, reducing the chance of sticking and scuffing. The only disadvantage of viscous oils - a slight increase in the hydrodynamic losses in the engine and, consequently, a slight increase in fuel consumption. " For brand new vehicles to use high-viscosity oil is pointless and even desirable in the running-in period, but for the moment when the odometer will begin to appear three-digit numbers, policy lubricants better reconsider. Despite the global "green" trends, notice which proposes products are widely known worldwide company Mobil: - for new cars: 0W40 - New Life; - for vehicles with mileage over 100,000 miles: 5W50 - Peak Life; - Pre-Owned More than 150 000 km: 10W60 - Extended Life. Such a "gentlemanly" set only confirms the findings of experts and my humble opinion. Necessary to mention such an important thing as an oil-based. That's it in a very large extent influences the final product price. Now there are several types of foundations: mineral, hydrocracked, semi-synthetic and synthetic. Just so, in order, and increases the cost. Cheapest - "mineral water", the most expensive - "synthetic". I will not zanudstvovat about the chemical composition and percentages of components, limit the practical recommendations. "Mineral water" is the cheapest, but worst of all "holds the punch" at a temperature difference. Accordingly, in the overheated engine "mineral water" to lose lubricity earliest and quickest turn into a solid in the cold. "Synthetic", in contrast, will resist longer than competitors, while maintaining the engine overheating, high speeds and keeping turnover at a killing frost. Resource motor depends on the lubricant, and "synthetic" number of kilometers to overhaul may be in 2-2,5 times higher than in the "mineral water", ceteris paribus. The last thing I would like to inform you this is just the classification in terms of quality, the above API. Obsolete Classes oil change on a new, satisfying current requirements for highly accelerated motors. The first letter «S» means that before you oil for gasoline engines (Service), «C» - that for diesel (Commercial). The second letter indicates directly at the quality. Usually on the cans, this information is provided by a dash: SL/CH-4 - newest product, the use of which is possible on most modern gasoline engines and diesel engines. Oh, and add a postscript: it is better to purchase "mineral water" well-known manufacturer, such as Shell, Mobil or Castrol, than for the same price to buy an unknown «.... Oil» in a colorful canister with protruding burrs and slogans such as «Fully Synthetic» , SAE 0W50, SL/CH-4. Motor tselee will.
