Absolutely no issues for any kind of modern petrol engine, be it turbocharged or NA. Interesting to see the delta between RON 91 and 95.

What does your manual or fuel lid say as such?

I just asked this question on Twitter about how much ethanol is blended in Power95 petrol and the MoPNG e-seva handle replied that it can have anything from 5 to 20 percent depending on the state!

I have been filling my E10 Hycross with Power95 and haven't noticed any issue yet, but I don't want to do the classic "muck around and find out".

After seeing the thread of how the E20 fuel filled XL6 failed emission tests, I don't want to take any chances.

What is an alternate fuel brand which can guarantee E10 compliance?

The 20% is alarming rather. But I found that the petrol pump owners and attendants are not very well informed on this matter. I will try and seek information through RTI and since both Indianoil and HP are PSU's they will be bound to answer.

But we also cannot discount the fact that these PSU's are puppets which dance to the tunes of Niti Aayog. The latter has a 2025 target for the 20% figure. Hence, the PSU's honchos while making their presentations before the Niti Aayog top brass would like to project themselves as 100 % plus puppets who are very faithful to the puppeteer.

In the meanwhile, the fuel from private sector petrol pumps like Shell and so on may be safer as their blending figures revealed to public are more reliable.

Thanks for taking the initiative. I will also prefer Shell, but the only thing stopping me is that there are not many credit cards which will give me benefit. I will have to switch to cash for paying at Shell.

Was reading the manual of XUV700 wherein it clearly says that Petrol Automatic versions need minimum 95 octane rating petrol be it BS-VI complied or E-20 while the Petrol Manual variants are rated at max E10.


Can someone enlighten me !

In a dilemma here Skoda TSI engine needs minimum 95 RON. But rated for maximum of E10. I can't go with Shell as RON rating is less. What is the best possible approach now ?

My Tiguan TSI is also rated the same and have been using XP95 for the last 1.5 years(25k kms) and no problems so far. HP Power petrol is another option, but XP95 is widely available even in tier2 cities as well. Didn't find Speed97 anywhere so far. But there are few pumps in Bangalore which provide XP100, Powe99 etc, but haven't tried them.

Well, as I read it they don't even specify what the octane number needs to be for the manual version.
It is remarkable that there is a difference in E10/20 rating between the manual and the automatic version, which suggest different engines or at least a few different parts. I don't think I have ever seen a E20 only recommendation either. Normally the E numbers are backwards compatible. So a E10 specified engine can handle E5 as well. I can't really think when a petrol with less ethanol would be harmful.

Also, as far as I am aware the E number stipulates the maximum ethanol percentage. Not necessarily the actual ethanol percentage.

E.g. Here in Europe a lof of the octane number 98 fuels are labelled as E5, but have no ethanol at all. Various companies such as Shell, BP, Esso and a few other guarantee no ethanol in their 98 octane.

That gunk means there must have been some sort of leak. Nothing to do with the petrol as such.

Those burn tests are useless. Petrol in an engine is sprayed and almost vaporised under pressure and high temperature. Looking at fuel burning under normal atmospheric conditions doesn’t mean anything.

Experienced it first hand today, unfortunately. Filled up XP95 from IOL COCO BKC Mumbai. Due to some technical issue, two of their regular dispensers were not working. Filled up from the corner dispenser, which is generally unused (first time for me filling from this particular dispenser, normally used as reserve).

Within 20 km of driving, "check engine" light started flashing. Toyota service engineer just called informing water in the fuel filter causing 'check engine' light flash!

Immediately email IOCL formally notifying them attaching the Toyota diagnosis. They usually take these things very seriously given the focus on RON95 & E20 in general.

Retain all documents!

This is probably an error. Write to M&M and seek explanation - also refer to their online manual in case that's more updated...

Thanks to all the contributors for this very informative thread. I am purchasing a Kodiaq TSI soon. Fuel filling instructions say RON 98 recommended and min RON 95.
1. Are IOCL XP95 and HPCL Power95 the only options then ?
2.Can I use a petrol which has a higher octane than 95 but not 98 octane such as as Speed97
3. While practically it may never be the case, (as XP95 should be easily available) but only from an academic POV, if choice is between 91 or 97 octane on one hand and a higher than 98 octane such as Power99 or XP100 on the other, what is recommended.

Hey..congratulations on your purchase - it's one family car I would like to have. Wish they had the diesel!

A lower RON is ok if you can't find the 95 but it will make your car gruff and you will hear it knock at higher geara at low speeds. A higher than 95 RON behaves no better than 95 RON and doesn't have any additional benefits - I mean to justify the higher price.

In cases when RON within specified limits is not available and you are running low, best is to fill enough fuel outside the limits that is sufficient to take you up to the pump with 95. Usually when I fill 91, I top up the rest of the tank capacity with 97 or 100 - my assumption being it kind of averages out the 91.

Hope this helps. Enjoy your new car!
