Hello everyone.

I just noticed that Bharat Petroleum outlet in Vadodara has labelled all it's petrol nozzles with E20.


The sticker of E20 is pretty fresh as compared to the diesel one and I tried talking to the attendant about when was the sticker put but unfortunately he didn't have a clue.

Does this mean that we already have E20 fuel with hardly any E20-capable vehicle?
Won't this have a disastrous effect on our current crop of vehicles?

Ps - I had filled diesel and that's why it shows 91.1/litre.
The price of E20 is still 96.4/litre.

I think the E20 and E10 would have slightly different density, but that may vary as well from pump to pump so it may not be the standard to gauge.

Filling up E20 on E10 compatible vehicles or lower would definitely have side effects in long term as Ethanol is corrosive so the parts must be lined to counter the corrosive property of increased ethanol. It might be pretty aggressive in older vehicles.
And no, there is no difference in rate of E10 and E20 fuel, at least not in my nearby pumps in Delhi. They charge the same even though the pump attendees agree that E20 should be cheaper.

I filled Speed 95 a few days ago. Attendant said it is E20.

IOC is selling E20 separately and not combining it with regular petrol. There are separate dispensers for E20 and marked clearly though the price is the same. As per the Niti Aayog recommendation, there has to be parallel availability of E10 and E20 for at least a few years from now. Only then we would have complete E20 being dispensed.

What? One would assume the premium petrol would be spared last.

Please view this depot invoice for XP95 at the bunk near my house. It says E12.


Till now I have not seen any E20 dispensers. And I havent seen any markings either anywhere.
Yesterday I filled XP100 in Ooty and that attendant said there is no Ethanol mix in XP100. But XP100 is seriously expensive.

Here you find the roadmap policy for the ethanol blending of fuels in INDIA for more information.





PDF file from the niti Aayog, whoever wants to have more clarity on the subject. Read Specifically Page no-61 onwards, most of the doubts being asked on the forum would be cleared.

Filled E20 petrol in my car yesterday night by mistake. I was traveling on the Eastern Peripheral Expressway where I first stopped at a IOCL petrol pump for refueling but the lone fuel dispensing pump working at night clearly indicated E20 so I went ahead and stopped at HP COCO pump for refueling. Saw the Petrol label and did not bother checking out the other sticker as I was too tired.

Today, I realized that the fuel I have added is E20. I am scheduled to travel again on Tuesday and look forward to empty the tank during this drive and be careful next time.

A query: Is E20 being sold at the price of regular petrol? As far as I remember, IOCL bunk displayed the sale price at Rs65 something.

The "premium" petrol is just higher octane petrol. Adding ethanol is one of the cheapest ways to increase octane rating

Referring to the Govt guidelines on the ethanol blending rollout( post #7) above, can we infer that when car makers these days are saying that cars are E20 compatible, they imply that their cars are E20 material compliant and E10 tuned?

Correct.

E20 tuned engine would be applicable from 01 April 2025.

What would be the impact of using E20 fuel in the E10 tuned engine post 2025? Would the efficiency be significantly impacted ?

Ethanol contains about 30% less energy than Petrol per liter.

So with 10% increase in volume of Ethanol; should result in minimum 0.5 Kmpl drop in mileage.

Just a rough calculation.

HP bunk, Yelahanka, Bangalore has a dispenser labelled e20 and Another one just Petrol. I asked the attendant what's the difference, to which he said he has been instructed that e20 is only for new vehicles. I guess the latter is e10, anyone could clarify pls ? Thanks in advance.

Well, this is an alarming development. Older cars will really suffer.

There still seems to be a great variation in the ethanol content in petrol across states (and possibly fuel pumps too?). While I was in Bangalore, I asked a Hindustan Petroleum pump manager about the ethanol content in regular and 95 octane petrol (Power 95). I was shown the invoice of the latest stock of fuel, and regular 91 octane petrol was E12 and 95 octane petrol was E10. This was on HAL Old Airport Road.

Last week, I enquired about the same at a Bharat Petroleum pump in Hyderabad (Indira Nagar), and on the invoice I saw that 91 octane petrol is E5 as of now. In all cases, the percentage was explicitly mentioned on the invoice.

However, I've gotten conflicting answers from pumps in Hyderabad. At an Indian Oil pump in Financial District, I was told that 91 octane petrol is E10 and 95 octane petrol is E5 (I could not see the invoice here).

I honestly don't know what to make of this. My sample size of 3 is small and rather inconclusive, hopefully other members can shed more light on this. Perhaps we could start threads for different cities to track the ethanol percentage over time?
