Myth 1: Do not fill in a fully synthetic oil in the engine, whereas before there had been flooded with mineral – it will curdle. Not true. Modern synthetic oils based on polyesters and polialfolefinov safely tolerate mixing with the mineral, semi or other fully synthetic oils. The only exception – synthetic motor oils on the basis of glycols, which are no longer manufactured (glycols in the car used now only as a component of antifreeze). Myth 2: Before pouring the new oil must be washed with the engine, such as spindle oil. Not true. Completely drain the oil from the engine can not: tire about 10%.

The rest of the 'wash', mixing with a new one (especially a good synthetic) oil, can unbalance an additive package. Therefore any 'flushing' when changing the oil used does not need! In the extreme If you simply reduce the interval before the next oil change (up to a value-depends on the contamination and the type of 'old' oil and engine). Myth 3: You can not fill synthetic oil in older engines, you can spoil engine. Not true. Synthetic oils can be poured in today's engines, as well as in older. However, the modern synthetic oil has good detergent properties and is able to wash away accumulated in the engine deposits. These deposits can clog the engine lubrication system.

Also, cleaning old and has already lost its elasticity seals, oil flushes sediment from the gap and cause 'leakage'. That these effects were the basis of this myth. To deal with them easily, after the transition to 'synthetic', the first interval until the next oil change should greatly reduce and replace all the seals are leaking. Myth 4: If you add a good synthetic oil Additional patented miracle additive, it will work even better. Not true. Do not do it! Oil producers spend tens of thousands of hours of lab experiments, 'rolls' millions of miles on the motor booths, picking up and balancing the additive package. Any addition of any substance may disrupt this delicate balance, and the best oil just lose some of their properties. And at worst, may form 'clumps', contaminating system of engine lubrication. Myth 5: The color and smell of oil can determine its quality. Not true. Organoleptic methods to determine the quality and composition of the oils can not. And the taste of it better not even try-in may include quite toxic components. Myth 6 I want to pour the engine oil for racing Formula-1, the properties it is superior to normal, as calculated on a more stringent operating conditions. Not true. The oil that is poured into the mechanics of race cars warm up the engine before entering the operating temperature, and then 'twist' them up to redline. Therefore, oil for cars Formula-1 is designed for high viscosity and very high mechanical and thermal loads. The price of issue, in the absence of universality, as well as significantly fewer resources, a few hundred kilometers, then the oil is changed and, as a rule, along with most of the engine (or motor assembly). While the conventional 'domestic' cars means that this oil is poured into the mechanics of his car (although, of course, use the same brand). Manufacturers produce and 'racing' oil for conventional cars, usually it is sold under names like Racing, Rally, etc. usually (though more expensive). But if necessary it can be poured into engines of ordinary cars.
