There is no difference in pricing. This is the kind of label the dispensing machines have. Photo taken from T-BHP only.

Thanks for sharing. I haven't seen this yet in my area in Blr. Will keep an eye.

I think this picture tells a thousand words
It has always been about foreign exchange issue rather than environmental impact

The forex savings due to ethanol will get offset by increased import of car parts due to people changing their cars sooner due to this E20 incompatibility.

Ethanol has a higher octane rating. In fact, one of the cheaper and easier ways to increase octane rating of lower grade petrol is to add ethanol to it.

Nothing wrong with using higher octane fuel. If your engine cannot compress the fuel enough to utilise the benefits of higher octane, then it would be waste of money but it won't cause any harm at all.

Using low octane fuel in an engine made for high octane will cause harm. hough However engines these days come with anti-knock sensors which sense the grade of fuel and then just reduce compression ratio. It will however lead to lesser power.

Ethanol blending and octane rating are two different things altogether. Higher octane rating doesn't mean ethanol is less or no ethanol. In fact, XP 95 is blended with ethanol too.

There will be a problem with old vehicles which are not ethanol ready but companies will manufacture suitable cars going forward because the government mandates it. I feel for at least the next 15 years the government should sell pure petrol to the owners of vehicles which are not ethanol ready. If ethanol blended petrol is priced cheaper, owners of new vehicles will automatically switch over. Gradually all older vehicles will be phased out.

The local industrialists and farmers will benefit no doubt, and I feel it better be them than middle eastern sheiks! The money will at least circulate inside the country, even if emissions remain the same. But I think they will reduce significantly, at lest at the tail pipe level within the cities. Similar to EVs.

Brasil did it in a planned manner and doesn't seem to face any issues. They actually seem to be doing very well. I read FIAT is the Maruti of Brasil and they offer cars that can take E0 to E100 and anything in between as well. And seem to be running just fine.

Here's what I have seen in Lucknow IOCL pumps:-

1) Fuel labelled as Petrol (Pretty sure they haven't upgraded the stickers on the dispenser nozzle)

2) Fuel labelled as Petrol E12

3) Fuel labelled as Petrol E20

4)Fuel labelled as XP 95 E12

The real beneficiaries of this implementation are the kins of politicians and no one else. The E20 push is from the top and there is ni way out for the end user. Farmers or the local economy takes a backseat.

I have a MY 2017 Ford Aspire TDCI going strong at 110000 kms. Although I have the itch to upgrade, dismal resale value and no suitable substitute (Diesel Sedan) is holding me back. I am also concerned about Ethanol blending and lack of torque/power, dismal fuel economy in petrol engines. I will spruce up my Aspire and hold it for another 3 years as the car is still mechanically robust.

Fortunately diesel is not yet blended with Ethanol in similar proportion to petrol.

Unfortunately, that’s not the case anymore. Diesel is also a 5% blend of biofuel (B5). This has been done silently and stealthily, no public announcements unlike E20.

Yeah I said not in similar proportion to petrol.

Isn't there a Gazette notification and a BIS Standard revision done to include this point? What else is a public announcement? It is no secret in India and globally that B5 Bio diesel is an accepted standard and is considered equivalent of regular HSD.


Press article by Indian oil who achieved an average of just 0.5% bio diesel blending for the year 23-24 in spite of selling XtraGreen https://iocl.com/green-fuel-alternatives

It's time we stop overly worrying about such changes. It's not decisions taken over a coffee table and involves consensus of various bodies including automotive manufacturers to consider the suitability of such changes. That's the main reason these things are ramped up slowly. The Bio-diesel blending target of 5% is by 2030, which is still not of a concern.

XtraGreen is not an issue, for there is clear branding that the fuel is a biodiesel blend. You know what you are getting.

Had biodiesel blending been so straightforward, why do the manuals of many cars explicitly warn against its usage?



EN590 (upto 7% blend) compliance has become mainstream only recently. Post BS6.

Furthermore, having a fuel bunk in the family, I can confirm that even dealers were not given any intimation of B5 being sold as normal diesel. It just happened. We found out from the invoices.

Now, everyone is compelled to buy biodiesel blend, irrespective of their car being compatible with it or not. More worryingly, unlike ethanol blending, where there is plenty of public awareness and a clear roadmap, there is zero public knowledge in case of diesel. People are simply unaware that they are getting a blend.

The owners manual refers to B20 or even B100 bio diesel when it says not to use Bio Diesel. The manufacturer should have been more specific in this case. Toyota clearly mentions that upto B5 is no problem and even slightly beyond that, the fuel filter replacement interval is reduced. They haven’t said no upto B20.

I believe Gazette notifications are considered official intimations by the government. For B5 like i said earlier, there needn’t be explicit labelling just like E5 petrol. Only anything above that needs labelling or branding. And you say its mentioned in the invoice clearly.
