Yes you can use XP95.
Like others have also said, you are very likely to experience better performance.

Slightly off topic : on adulteration. Experienced the worst last week. I always will XP95 in our taigun and get a mileage between 15-17 on highways. The one time, we filled a tankful and was touching merely 12. The pump is in Kochi\edappally road in the highway near anchumana.

Indian oil confirmed the percentage of ethanol blending of their higher RON fuels, the XP95 and XP100 to me via instagram.

This is deeply concerning.
I use XP95 and the max my car can take of Ethanol is 10%.

HP launches 95RON petrol. Also confirms their Power variant was already 93RON.

Targeting owners of SUVs and high-end bikes, Hindustan Petroleum Corporation Ltd (HPCL) has launched the Power95, a petrol product that has higher Octane number than its Power variant that has an Octane of 93 and regular petrol, which has an Octane of 91.

Finally! Had been waiting for this as IOCL 95 octane is hard to find in my proximity. HP COCO's are plenty. Hope the roll out is quick and pricing is at par with 95 octane of IOCL

Now only if they launch a diesel at par with Xtragreen's cetane level

I have a query for the experts to answer. What should be the density of XP95 octane petrol. Should it be more or should it be less than the normal 93 octane petrol. At some fuel pumps I have noticed that XP95 octane petrol has higher density. But, sometimes I have also observed XP95 octane petrol to have lower density. Can there be some kind of scam running on.

How do you know it is of different density?

Irrespective, the higher the octane number, the lower the specific gravity or specific density. There is a similar correlation to energy per unit. The upshot of it is that you need to burn more high Octane fuel compared to a lower Octane fuel to get the same output power.

In practice the differences are very small. Also, engine suitable for higher Octane numbers tend to have higher compression. Higher compression with everything else the same will increase efficiency.

But of course, the compression ratios in our engines are fixed which means, yes, in theory using a higher octane fuel lowers the efficiency due to the above effects. However, also in practice, those engine that run well at slightly different octane fuels, tend to run a bit more efficient overall, due to some other effects.

But as I have often pointed out, the effects of a higher octane fuel for engine that was not designed for it, tends to be a waste of money. In the end it all depends on your engine, whether you will see some effects or none, or in fact what can happen, lower performance on high octane fuel

Thanks for the response. The density is generally displayed along with the price at the pumps itself. Typical values lie anywhere between 745 to 764 g/ml.
I just wanted to know that is there anyway where a layman could identify the difference between normal petrol and XP95 petrol. I thought may be density values will give us an idea about that. Or we are at the mercy of the petrol pump and their honesty.

Picture showing density of IOCL XP 100
And another picture showing density of normal 91 Petrol IOCL.

Never go by the display on the dispenser most are faulty! Law mandates that the pump owner keeps a density register with morning readings, as well as displays density readings on the stock board, as a customer you can always check on those and that can never be manipulated. The dealer also has density hydrometers and temp meter for refrence if a customer so desires to check the current value which should as per law be +\- 3 as per last invoice reading.

Interesting. I must admit I really can’t remember seeing these density readings on petrol pumps in India. I must have missed it. Do these pumps measure the density themselves? Or is it just a displayed value that is set?

Hydrometers, even when properly calibrated and compensated for temperature get an accuracy of not better than +/- 5% of full range. Given how a hydrometer is likely to be used by the average Indian Petrol attendant I would not place much value at these readings no matter what.

What is the purpose of displaying the density?

The dispensers that display density are the new gen STP dispensers, their suction motor is in the tank below itself. The latest fuel tank running on the latest automation module will have a automated probe in the tank that displays stock level as well as density reading.

However in most cases there is always a glitch in density readings and the display will read 760. The purpose of displaying it was for customer benefit as they could compare the density with that displayed on the daily stock board.

Been running on XP 95 on my Taigun 1.5. Note that 95 is the recommended octane rating for the Taigun. I am quite sensitive to how the car behaves and the few times I’ve had to “normal” fuel, I’ve felt the car to be less powerful and return lower mileage. I wanted to check on Speed 97 and was passing by Pondy which has a BP bunk operated by the Ashram - where one can be sure there is no hanky panky. Did a full tank of Speed 97 and have driven 200 km since. There is something off with Speed 97. The engine feels a little sluggish, rough and less responsive. I think the additives aren’t good. Can’t argue that the first tank is cleaning up the engine as I’ve run only about 8k in less than 2 months on the Taigun.

I am going to be sticking with XP 95!

Being a long term user of Shell VPower (4+yrs) in my cars, I shifted to XP95 last week for the very first time. I wasn't aware that VPower is a 91 RON fuel with additives. I always thought it is 95RON. Pick and smoothness was always good , but I was shelling INR 126/litre every time .
XP95 has made a big impact to the vehicle's smoothness in terms of engine noise, pick-up, acceleration etc. I wondered why I wasn't trying anything else before.. But going forward XP95 at INR 109/lite at COCO outlets will be my only fuel. Bye Bye Shell
