Today cars have become as one of the basic requirement of every house. Advancements in various fields have mandated every individual to own a car. But, cars need adequate amount of gasoline to travel. This gasoline is available to the public in various concentrations and octane numbers. Now, what is that octane number? We know that a spark-ignited internal combustion engine undergoes 4 steps to complete one cycle namely, intake, compression, power and exhaust.

The fuel which has low compression ratios, when compressed produces a flame front with the gasoline. But, before the flame occupies entire space inside the cylinder, some unburned fuel gets ignited separately before the main flame reaches the unburned fuel. This improper function of the engine produces a rattling sound inside the engine thereby corrupting the performance of the engine and this process is termed as knocking. In order to prevent knocking, usage of fuel with high compression ratios can help you in a great extent. High compression ratio of the fuel corresponds to the octane number of that fuel. Octane number is nothing but the resistivity of the fuel against the premature detonation or ignition. Hence the loss of the fuel can be greatly reduced and the speed of the vehicle can be increased considerably.

In developed countries, gasoline is available in various octane number specifications like 87, 89, 91 etc. Each number corresponds to the increasing resistivity against the premature ignition. These octane numbers are also classified as regular, midrange, premium, super premium, etc. Regular is suitable for ordinary vehicles which are used for commercial purposes. Not all the vehicles are compatible with the fuel with all these octane numbers. Only vehicles with the turbo engines can go for fuels with the octane number 91. Moreover, there are also small bottles of octane boosters which can boost up the speed of your vehicle by simply mixing with the regular fuel. If an octane booster of number 3 is used with the gasoline rated 91, then the total strength of the fuel shall be 94. But, usage of minimum amount of octane booster around 0.3 is enough to reduce knocking in your vehicle. Mentioned below are some of the octane boosters which can improve the efficiency of your engine by reducing the rattling sound.
