IOC will provide XP100 premium petrol at select outlets of IOC in 10 cities -- Delhi, Gurgaon, Noida, Agra, Jaipur, Chandigarh, Ludhiana, Mumbai, Pune and Ahmedabad.

Indian Oil Corporation (IOC) on Tuesday launched the nation's first 100 Octane petrol, helping India join a select league of nations globally that have such superior quality.

The fuel is manufactured at IOC's Mathura refinery in Uttar Pradesh and supplied at select petrol pumps, he said.

Octane ratings are measures of fuel stability.It is a measure of a fuel's ability to avoid knock.

Knock occurs when fuel is prematurely ignited in the engine's cylinder, which degrades efficiency and can be damaging to the engine.

The higher the octane number, the more resistant the petrol mixture is to knock.

Worldwide, 100 Octane petrol has a niche market for luxury vehicles that demand high performance and is available only in six countries of USA, Germany, Greece, Indonesia, Malaysia and Israel.

At most retail stations, three octane grade are offered, 87 (regular), 89 (mid-grade) and 91-94 (premium).

Pradhan said Hindustan Petroleum Corporation Ltd (HPCL) had recently launched Octane 99 and now IOC has come to the market with XP100.

"This is a testimony to India's technological prowess and manufacturing it within our refineries is a shining example of Aatmanirbhar Bharat (self-reliant India)," he said.

Previously, the nation leapfrogged from BS-IV (Euro-IV) emission compliant fuel to BS-VI from April 1 this year.

"This was done by upgrading refineries at an investment of Rs 30,000 crore. And today we are joining the elite group with XP100," he said.

IOC plans to roll out XP100 premium grade petrol in the second phase in Chennai, Bengaluru, Hyderabad, Kochi and Kolkata.

Ah, such wonderful news. Praise be the automotive gods, it seems that the voices of us enthusiasts are finally being heard.

But wait. There’s one tiny detail missing. What of the price per liter? Surely that’s an important detail to leave out in a news release like this.

Well, that’s because they haven’t got the courage to show or mention the prices. Grab a seat, and be ready for this. Or break out in peals of laughter, as I did.

Fuel prices are getting progressively crazier. Petrol is pushing 90 a liter in Bombay, 97 about 110. This though, is another level of nutty. Surely these prices are unsustainable and won’t see much momentum.

Be right back. I’d rather smoke rubber than whatever special stuff these guys are on a steady diet of.

How to make something looking cheaper. Bring out something more expensive.

Now does our diesel/petrol look cheaper.

[Sreesh1009]

Good news for supercar owners but that ₹160 per/litre rate makes memy stomach funny. I understand that people who've spent crores on their vehicles won't care (hope to reach that stage of life soon).

Surely does make Petrol and Diesel look cheaper :")

Actually, octane 100 is available in more countries than the 6 mentioned in the article. E.g. the Netherlands.

But in all those countries they are finding out it has virtually no use. There are very few cars that would actually benefit from it. Even supercars are designed for run off the mill petrols. You don’t get a different compression ratio by changing the octane number. Ignition advance will only give you an advance, pardon the pun, up to a point.

Even so, there are in every country, many, many punters who will happily shell out big bucks for high octane petrol and claim unbelievable performance improvements. And these are typically not the supercar boys either.

Making matters worse is the fact that the powerful cars needing 100 Octane petrol will be delivering 2 kmpl. That's a fuel cost of 80 bucks a km

[CEF_Beasts]

I read some where that a person had filled this 100 octane fuel in his Porsche and he said the gain in performance between 99 octane and 100 octane was very minuscule to even consider the ₹160/L compared to the 99’s ~₹100/L. Also ₹160/L is the price in Delhi is it the same in Mumbai and other cities as well?

[NaXal]

They should consider home delivery of this fuel. Super car owners can definitely afford, yes certainly this number may feel pinching but they can certainly when they are driving a car costing few cores !!

Beside, home delivery may allow the owners to have some storage at home. Saving the trip to fuel station.

Specially the super bikes with puny tanks & outrageous fuel economy. One may end up spending half a tank just commuting to the bunk located at other end of the city & back.

Guys, sorry for a noob question, can we use this 100 octane petrol on normal Maruti and Hyundai cars and scooters like Honda activa and Yamaha fascino, will it make engine any smoother or would it give better performance (instant pickup / power surge as 100 octane burns much faster than normal petrol) compared to the normal petrol?

On the flip side are there any negatives in using 100 octane premium petrol in regular cars like affecting fuel pump, injectors, apart burning a hole in our pockets?

[Turbanator]

Checked with another Bhpian, who knows about this stuff, IOL is also adding additives like what HP & BP does. So essentially, these companies are adding additives like Proctane maybe a different brand or a higher quality.

Will be interesting to check long term effects, perhaps soot on spark plugs can give some indication?

Haven't experienced personally yet and nor do I have any plans, he must be correct. If the engine is not tuned to work with such octane rating, there will be no benefits.

Looks, IOL took the cues from the other narratives, bigger or larger is better. Will be a complete flop in my opinion. Instead, they should have launched a premium fuel at 1000 + pumps given the wide reach of their network over others. That would have given them more business and would have helped people with such cars/ suvs travel further than cities.

good idea, they should explore given the costs (margins).

No benefits, no losses except the monies that you will be giving to IOL. But, if this brings any smile to you, no harm in trying

It won't result into any improvement in the performance or the fuel efficiency.

As explained already on the forum, high octane petrol helps the engines with higher compression ratio (> 10), which are susceptible to knock on the normal petrol. But even the octane level of the normal petrol has gone up in the last decade.

While I don't know about Maruti or Hyundai, my owner's manual of the '07 Honda City Vtec speaks of how different region models need different octane petrol. So maybe our cars are tuned to accept only a certain type of petrol and changing that may not be the best choice.

On the flip side are there any negatives in using 100 octane premium petrol in regular cars like affecting fuel pump, injectors, apart burning a hole in our pockets?

Many years back, I was told by my Honda ASC that using the premuim petrols will do more harm than good and that is why Honda does not have any additives that they fill/recommend during service. IIRC he had told me that it may affect the throttle body and that may lead to a drop in acceleration with lower FE.

It is anything but a noob question. Good quality low octane petrol has higher specific energy. Increase in octane rating is usually achieved by diluting specific energy. Purely from "energy density/energy per gram" point of view, higher octane fuel is inferior. Yes, it is an inferior fuel that can withstand higher compression. On the other hand, engines with higher compression ratio are better at extracting more energy from petrol. So you get the best bang for your buck when you find the optimum combination of specific energy and engine compression.

Putting higher octane fuel in standard engines may result in poor fuel efficiency, but might feel a bit smoother due to absence of any knocking.

Putting lower octane fuel in high compression engines will result in knocking, but ECU will alter a bunch of parameters (ignition timing and air/fuel mixtures, etc.) that will make the engine do poorly in terms of performance, smoothness and fuel efficiency. This is done to protect the engine from damage and I think they do a fairly good job.

Then there is the big question of how higher octane rating is achieved, how much energy dilution is taking place? Octane can be boosted by adding stuff that has no energy.

It is normal for the engine manufacturer to specify a minimum octane number for the petrol to be used in a particular engine. Hence for India, it says "RON of 87 or higher".
The different mimima specified for the different regions gives you an immediate indication of how de-tuned/de-rated this particular engine is for markets where higher octane fuel is not widely available.

As several people have mentioned, using a lower octane fuel than specified will result in fuel detonation, or 'knock', if the octane number is too much lower than the recommended level. All else being equal, using a higher RON fuel than the minimum recommended will not harm the engine in any way.

Similarly, diesel engine manufacturers also state minimum Cetane Index or Cetane Number specifications for their products. The below is from a generator engine, but the principle is the same. As long as the Cetane Index of the fuel is higher than the minimum specified then the fuel is suitable for the engine.

EDIT: The bit covered by the T-Bhp watermark says 'Cetane Index'.

Wiki has this to say,

Octane ratings are not indicators of the energy content of fuels. (See Effects below and Heat of combustion). They are only a measure of the fuel's tendency to burn in a controlled manner, rather than exploding in an uncontrolled manner.[3] This is important to know when choosing a fuel for a particular engine. Performance is optimized when the lowest octane rated fuel that can be used without detonation is used.

It also says,

Where the octane number is raised by blending in ethanol, energy content per volume is reduced.

https://en.wikipedia.org/wiki/Octane_rating

We have started blended Ethanol for a while in India, which also explains the increase in or RON as standard.

https://en.wikipedia.org/wiki/Octane_rating

However, all the oil companies add additives to the regular fuels to increase the Octane numbers in India, so I am not sure if your point on the fuels with higher octane number with lower energy hold good in our case.
