Gasoline - how we deceive

Almost half of the car refueling deceives us! According to the Rosstandart now about half of the gas station Russia octane fuel is lower than claimed, reports "Izvestia┬╗.

"We spent last year testing 560 gas stations, violation of the technical regulations identified 232 stations. Compiled by 426 protocols of administrative violations. The total amount of fines reached 1, 94 million rubles. ", - Said the head of the Federal Agency for Technical Regulation and Metrology (Rosstandart) Grigory Elkin.

"Now the most popular improver of gasoline in Russia is methyl tertiary butyl ether (MTBE). Its maximum permitted concentration is 15%. The problem is that it boils at a temperature of 55 degrees, while the gasoline evaporates very much worse. Therefore MTBE from gasoline evaporates very quickly. This is especially noticeable during the summer heat, "- said the publication of Head of the Institute of refining gasoline Vyacheslav Emelyanov.

And how is cheating customers. Typically, oil storage depots were mixed in equal proportions of the AI-92 and AI-cheaper 80. Then, this mixture was added the MTBE, and the output is again obtained a 92-octane gasoline. This technology allowed the guests, and the resulting fuel meets standards. But only until such time as MTBE starts to evaporate. A little bit out of the tank during transport, a little in storage at the gas station and fill up. As a result, the tank is not often 92nd gasoline and fuel with an octane rating of 91 or even 88.
