Memories of the Soviet gasoline in motorists are only positive. Perhaps this is due to a low price of gasoline or with steadily good quality for those years.

In principle, then everything coincided: demand, price, quality. Sometimes it lacked the quantity, but this is a separate conversation.

Today, let us remember about the color of gasoline. Yes exactly.

Few people remember that earlier the gasoline brand could be determined in color. The case is not at all in special production, but in ordinary dyes.

According to GOST in Soviet times, it was necessary to paint fuel. And why this was done now we will tell you more.

Immediately it is worth noting that the dyes did not have a negative impact on the car’s fuel system. Everything burned without a residue.

So the motorists did not need to be afraid of non-ferrous fuel, and harm to the engine of the car.

In the past, fuel began to paint exclusively from rational considerations. Since gasoline species were not too much, the color gamut was not great.

The most popular fuel grades: A-66, A-72, A-76 and AI-93. As you can see there are consoles «A» and «AI.» The difference between them is exclusively in the octane number.

More precisely in determining the octane number. The brand «A» is determined by the engine. «AI» is a research.

At the end of a small excursion, I would like to notice that the octane number of the research method is greater than the engine.

The main addiction of the detonation was in those times tetraethylswin. Due to this element, an octane number increased.

Due to the name of the additive, gasoline was called ethyl.

Of all the above brands, non-ettenited was A-72. There were other additives in this fuel.

As mentioned above, according to the GOST of those years, gasoline should have been stained in accordance with the brand. AI-93 had a blue color, A-76 — green, A-66 was generally stained in orange.

And the dear to our heart A-72 has long been eaten and got his pink shade.

So it was much easier to distinguish the brand of gasoline from each other and workers of oil stations and motorists.

Over time, the standards changed, however, as well as the fuel itself. Now in our country does not find colored gasoline.

Even if someone will notice any color of the fuel today, it will take this fact for the sale of a low-quality product.

But abroad the color palette of fuel is still widely used.
