Motorists often wonder whether they should fill up with regular petrol or opt for 'Power' (premium) petrol. Some believe premium fuel improves mileage or extends engine life, but what is the real difference?
Currently with the increase in fuel prices, we are here with an explanation about the normal and power petrol.
What Is Octane Rating?
The main difference lies in the octane rating, which measures how smoothly fuel burns in the engine. Regular petrol usually has an octane rating between 87 and 91, while 'Power' petrol ranges from 91 to 95. (However, one can refer expert ideas over the values). Higher octane fuels prevent knocking - a knocking sound caused by rapid or uneven combustion - ensuring smoother engine operation.
Engine Cleanliness and Additives
Premium petrol also contains specialised detergents and chemicals that clean engine parts, such as fuel injectors and valves. This helps reduce carbon deposits, potentially prolonging engine life and improving performance.
Why Is Premium Petrol More Expensive?
Premium petrol costs slightly more due to the complex refining process and added chemicals needed to achieve higher octane levels. These factors increase production costs.
Which Fuel Is Suitable?
Contrary to popular belief, premium petrol does not significantly boost mileage for all vehicles. It is mainly beneficial for high-performance, expensive cars with high-compression engines. For most everyday scooters and standard cars, regular petrol is sufficient and safe. Using premium fuel in such vehicles is unnecessary unless specified by the manufacturer.
