Find out how these oils differ and what advantages synthetic lubricants have.
Many people know that synthetic oils work better than mineral oils, but not everyone can explain why this is so. What is the main difference between synthetic and mineral motor oils? Almost everything.
Mineral oil is actually extracted from the earth — it is simply refined crude oil. Synthetic oil (fully synthetic or semi-synthetic) is created in the laboratory.
In the production of best synthetic oil, oil is not only refined, but also undergoes a process of distillation and is then processed to form basic molecules. Then base oil is made up of these molecules and is improved with the help of additives, due to which the final product will have exceptional working properties: reliably protect against wear, exposure to extreme temperatures and the formation of sludge deposits. This process allows not only to remove more impurities from crude oil, but also to process each individual oil molecule in accordance with the needs of a modern internal combustion engine. Such "processed" molecules guarantee a higher level of protection and efficiency and help the engine to work without failure even longer.
What is the advantage of synthetic oil? Here is how all these chemical processes work in real life:
When circulating in the engine oil can accumulate sediment. If you use a mineral product, with time inside the motor sludge deposits may form, due to which the efficiency of the engine will decrease, and as a result its service life will be reduced. Synthetic motor oils contain less impurities than mineral, and more effectively fight with the formation of sludge, which allows them to reliably protect your engine from the appearance of deposits.
Reliable wear protection
Parts of the engine are in constant contact with each other, while moving at high speed. Working in such extreme conditions may cause wear and tear. The protective barrier between the parts is motor oil. Mineral oil at some point begins to break down and lose its protective function. Synthetic oils, on the other hand, retain the ability to provide protection against wear for much longer, thus increasing the life of the engine.
Excellent fluidity at low temperatures
When the car is standing still for some time with the engine off (for example, at night), the oil thickens. But when you turn on the ignition, it starts to pump, protecting the engine parts from friction. Mineral oils need more time to begin to fully circulate in the engine. In winter, or in regions with extremely cold climates, this process takes even longer. Synthetic oils, by contrast, are created using a special technology that allows them to maintain excellent fluidity even at low temperatures: they begin to protect your engine as soon as you start the car.
Car for half a year and half a life: buying a car in France
Buy a new car? Directly from the car dealership? In France? In 40 years? Yes, you are crazy! After all, she - the car - in five thousand kilometers will lose 20% of its value. And after 50,000 kilometers (which is pure indulgence for normal technology), another half. “And why should I, a simple working man, an honest taxpayer, have such hell of a waste,” think the French and go looking for a car in a “lightly second-hand” state.
Here our compatriot should feel perceptibly uncomfortable. Because buying a car from hands in Ukraine is a Russian roulette, where at stake is hardly accumulated funds for the purchase of personal vehicles. And just one chance for good luck. After all, anyone who comes to the secondary car market in Ukraine is well aware that the sellers have already taken their car over the years of living together on our roads. And buyers become heroes of the story about the gypsy horse. For those who are not in the subject, briefly retell. So. The Gypsy sold a horse to a certain gullible Vasya in the market, and she take it and die with the buyer the next day. Angry, Vasya comes to the market and says to the gypsy: “And what is your horse that died?”, And the gypsy answers him: “You are a bad master. She lived with me for 30 years, and never once did anything like that. ”
So, choosing a car in France, you can be calm, at least in matters of the passport age of the Gypsy horse. Worried about customer dishonesty? Go to the car dealership. Each brand has an impressive range of their own cars, but with mileage. The people who wish to change the car, brings it to the dealer and delivers through the trade-in system. Sells safely, with a bunch of guarantees and a clear conscience. And the dealer launders the machine, polishes, checks, confirms the entire maintenance history, tests, evaluates - and sells it right there, from its site to another interested person. Again, it sells safely, with a guarantee for components and assemblies, insurance and paperwork.
And this is how it works. The very trade-in that in Ukraine will not develop in any way (we have any movement towards your car from the official dealerships by default is more expensive than “garage maintenance”), in Europe is in steady demand. A French car enthusiast would prefer to overpay 300 euros to a car dealership than to risk in an unprotected act of financial closeness with unscrupulous sellers.
