What gasoline is better

Any motorist comes the moment when he asks himself a question - what gasoline is better to pour into the tank of his car. By and large, only three brands of gasolines are presented on the market - this is AI-92, AI-95 and AI-98. So we will consider the urgent question, what is still better.

First you need to look into the instructions for using the car. It will necessarily indicate a fuel-recommended manufacturer. It should be noted that the statement indicates an octane number that is minimally sufficient for this engine. Thus, in the absence of this brand, it is possible to pour 95th gasoline instead of the 92nd gasoline. The recommended gasoline brand is also duplicated on the label from the inside of the benzobacing shell.

It should be noted that domestic servicemen very often urge gasoline with a large octane number than indicated by the manufacturer in the service book. This motivated by the fact that more expensive fuel is better and more economical. This, with rare exceptions, just a lie. Moreover, the high-octane brands of expensive gasolines are much more likely to falsify than low-octane. And this can already lead to a serious accident of your engine.

It should be remembered that dishonest producers make high-octane gasoline by mixing in cheap iron-containing anti-knock additives of ferrocenes. Such gasoline, even after the first refueling, with a high probability, completely kill the spark plugs. Experienced motorists perfectly know this effect called "Red Death". The iron contained in the fuel is settled on the insulator of the candle, as a result of which the insulator loses its properties and its surface turns into a conductor. The spark is simply not formed between the electrodes, and the engine begins to work unstable - troit.

Separately, high-octane gasoline should be noted. These are gasoline AI-98 and higher. They are intended for high-profile engines with turbocharging. Therefore, if you have in use, for example, Mitsubishi EVO, it is better not to experiment, but apply fuel with the maximum possible octane number.

There is a simple rule for understanding, on which gasoline is better ride: if the degree of compression of the engine of your car is less than 10.5, then it means a low degree of motor forsing. And it is designed for fuel from the 90th octane number. Therefore, absolutely bold can be used during the operation of AI-92. In all other cases, gasoline AI-95 and higher is required.

Let's summarize the brief results. Always choose gasoline with a minimally sufficient octane number. More expensive high-octic no advantages will give you, except for additional costs and increasing the chances to expire to falsification. And always refuel on proven gas stations, and not on the side of "Vasi". Good luck on the roads!
