Petrol is like blood for the car, which makes the engine run optimally. The wrong choice of petrol may damage your car in the long run. Low-quality fuel can cause sedimentary deposits inside the engine, which is detrimental in the long run. So, if you have bought a new car, or are new to driving, the options of petrol types at the fuel station might concern you. If anything happens to the engine, having insurance for four-wheeler may not cover the repair cost.

Therefore, it is important to understand the major difference between all these, especially power petrol and normal petrol. In India, you can choose between normal, premium, and high-octane petrol. Therefore, this article talks about power petrol vs normal petrol.

Power Petrol vs Normal Petrol

The major difference between power petrol and normal petrol lies in the amount of octane present in them. Power petrol has a very high amount of octane, and normal petrol has low octane. Octane is the measure of how much compression a fuel can withstand before ignition.

Octane rating is an index of the fuel’s resistance to heat and premature burning, which makes the engine “knock”. A car’s engine works by compressing air and fuel to ignite them. When you use normal petrol, the compression of air and fuel increases and causes pre-ignition or premature burning. This pre-ignition is known as a “knock”.

What is Power Petrol?

Power petrol has a higher amount of octane and is more resistant to pre-ignition. This is the reason why high compression engines require premium petrol. You must know that premium petrol is commonly used to refer to power petrol. Different brands sell high octane fuel under different names like ‘Speed’, ‘Power’, ‘Extra Premium’, and many others.

Normal petrol has an octane rating of up to 87. Mid-grade petrol has an octane rating between 88 and 90, and power petrol’s octane rating is within the range of 91 to 94. Power petrol octane number is higher, which helps to reduce engine-knocking and detonation. This leads to better combustion. High octane petrol also helps the engine to work at full capacity and leads to better fuel efficiency.

Remember that power petrol is beneficial for vehicles that have high compression systems. For example, if you have a sports bike or a sports car, you must be aware of the power petrol octane rating before fueling your car. Performance-oriented motor vehicles have engines with a high compression ratio. The higher the power petrol octane number in the fuel, the better performance the engine churns out. Definitely, it is not recommended for every vehicle as most of them can run on normal petrol.

Thus, now you know what is power petrol, the power petrol octane rating, and the difference between normal petrol and power petrol let us move ahead.

Are There More Advantages Of Using Power Petrol?

Apart from reduced engine-knocking and detonation, power petrol has many other advantages. They can be summed up in the following points:

  • Power petrol leads to better fuel efficiency than normal petrol. As a result, it increases fuel economy by improving fuel combustion.
  • Power petrol reduces engine knocking, due to which the vehicle’s speed and power increase.
  • Cars that use power petrol have fewer emissions from silencers, making a less environmental impact.
  • Power petrol eliminates the deposit of intake valves and fuel injectors present in engines.
  • The driving experience improves due to more power, speed, and better economy of the vehicle.
  • Power petrol manages and improves the Octane Requirement Increase (ORI) of the vehicle. The accumulation of deposits in the combustion chamber can increase the engine’s appetite for octane, known as the Octane Requirement Increase. Therefore, power petrol leads to fewer deposits because of better combustion.

In today’s time when almost every family owns a vehicle, it becomes important to know about various petrol types and the right one for your car. Using efficient fuel is very important to keep your vehicle safe in the long run.

But many people might not be sure which grade of petrol to use for their cars. Power petrol has many advantages over normal petrol. So power petrol can be a good choice if you are looking for a better driving experience and better vehicle strength. But it is also important to know when power petrol is actually needed.

When to Use Power Fuel?

There is a misconception that power petrol always makes a car move faster. But unless the engine knocks or rattles when driven on normal petrol, power fuel is not needed. So it should be used only when the car’s manual recommends it. If a car can run on normal petrol, then there is no extra benefit of using power petrol.

Additionally, it is important to know that normal petrol in a car that requires power petrol will lead to reduced power and speed. Moreover, if you use power petrol in a car that requires normal petrol, you may end up spending more money.

If the car’s manual says that it does not need power petrol but also says that it will run better on higher octane fuel, you can use your judgement to make a choice. The cost may increase if you choose power petrol, but you can benefit from less fuel usage and emissions.

What Other Steps Can You Take to Protect Your Car?

Car maintenance involves many steps. Periodic maintenance, including changing engine oil, coolant, and other consumables, is crucial for the well-being of your car’s internals. Having said all this, in today’s time, insurance for four-wheelers is absolutely essential, not only because it is mandated by law. Taking a car insurance policy is an integral part of maintenance that many people fail to recognise.

So, if you have bought a new car, or your existing car insurance policy has ended, it’s in your best interest to purchase insurance for a 4-wheeler from Tata AIG.
