If you cannot answer these questions, this article deserves your attention. After all, you do not want to harm your vehicle and neither you aim to waste money on fuel that is not required by your vehicle.

What is octane and how different is it from regular fuel?

Octane is a rating, and it is not a different fuel. In fact, the regular fuel at a petrol pump is also an octane fuel. However, the rating of the octane fuel varies. A regular fuel carries an octane rating of 87, whereas a premium fuel has a rating of 93 or more. The octane rating is a way of measuring the ability of the fuel to avoid knocks.

A slightly more elaborate definition of octane

Inside an engine, knocks (they are harmful to the engine) take place when the fuel is ignited prematurely. However, it is not felt because, in the fuel, an element is present by the name oxygenate that prevents the knocking. Higher the octane rating, the lesser the knocks. Not to forget, a higher rating also means the fuel can withstand a high compression ratio, which also prevents untimely and frequent knocks inside the engine.

What octane fuel should be used in vehicles?

In the manual book of every vehicle, the manufacturer prescribes the octane rating. Therefore, it is advisable to use the prescribed octane rated fuel. There is no point in filling up a vehicle with expensive fuel because the engine is not designed to use that fuel to its true potential. Therefore, one should stick to the octane rating as mentioned in the vehicle’s manual book.
