Over time, deposits appear in any engine, fuel injectors become clogged with dirt. This process is not fast, but the older the engine, the more various impurities accumulate in it. In order not to fix the case, many advise periodically driving at high speeds. So, so the engine is being cleaned. However, everything must be handled wisely. The AvtoVzglyad portal tells where such a cleaning can lead.

Driving at high speeds is really good for the engine. Vibration causes the valves to rotate, reducing the risk of uneven wear. The amount of exhaust gases is also growing. They clean the boost system and the bypass valve, and they get dirty if the driver wants to save fuel, because it doesn’t load the turbine. By driving at 4000 rpm for about an hour, the temperature of the turbine rises to the maximum and deposits are removed. But not everything is so simple.

Such a long journey at high speeds increases the probability of variator breakage. The fact is that such a transmission does not like prolonged high loads, because in this case the working fluid does not cool and the likelihood of overheating of the transmission increases. That is why you clean the engine, but you condemn the variator to repair.

It is not necessary to save fuel for such a “grip”, because it can also end in failure. If you pour “bodyagu” into the tank, they say, to save money, the dirt that gets into the tank will very quickly clog the fuel pump screen. At best, the engine will suddenly lose traction and at worst it will simply stall as the fuel pump will no longer be able to pump fuel efficiently. You will need to remove the pump, clean the fuel receiver grille and the tank. And this is a long time, and in the field not everyone will be able to cope with such work.

Finally, if the car has been standing still for a long time, we recommend that you do not immediately load it heavily. The fact is that condensate accumulates in the engine oil during parking. The lubricant becomes as an emulsion, which boils under high load and temperature rise to form gas bubbles. This leads to local overheating of the power source and a decrease in the resource. So let the engine run first, drive through the city and only then can you make a trip of many hours. this way you really clean the engine and prevent problems in the future.
