-   -   List all cars that are E20 and E20+ petrol compliant (https://www.team-bhp.com/forum/indian-car-scene/260641-list-all-cars-e20-e20-petrol-compliant-6.html)

Old cars (BS3) usually are not compatible with E20 fuel.
Engine and fuel system as such might not see much degradation, except for drop in fuel efficiency (8-12%) and similar drop in performance.
But plastics, synthetic and rubber hoses which come in contact with E20 fuel will undergo enhanced corrosion. this is my view based on what i have read over multiple sources from internet and ARAI report.

This is not in the context of warranty.
I saw a website which refers to a Toyota India senior functionary declaring that all their petrol vehicles over the past 10 years can run on E20

(Sorry if it is a repeat post)
Not sure how far reliable.

I think the current E10 fuel will continue in parallel with E20 fuels for new cars. There will be separate dispenser for E20 fuels and it will be mentioned there.

Yes, i read that, but not sure if he meant the UC as well, since the UC is actually manufactured by Maruti

In an ETAuto Interview with C.V. Raman (Maruti Suzuki’s CTO) on net-zero carbon emissions goal by 2070,
from timestamp 17:11 to 22:11 C.V. Raman speaks about E10, E20 and Flex Fuels.

Below are the snippets from the interview:

If those were already compliant with E20 petrol, it would not have made news now.

E10 will be sold till 2028 it seems. Car manufactured after 2008 are supposed to be E10 compliant.

Not sure about this to be fair. This is from the user manual. :sadface

I see much less discussion on this than one would expect, given that almost all owner manuals mention only E10 compatibility

As it stands today, 99-plus% petrol vehicles on Indian roads are not E20 compliant. There is no way govt. can pull the plug on E10 petrol by 2028 (just 5 years away), rendering millions of petrol vehicles at risk of multi-organ failure! They have to sell E10 petrol for at least another decade.

I don’t have a problem with E20 usage but from a consumer point of view it’s a loss as ethanol has a lower energy density compared to gasoline, which means that it takes more ethanol to produce the same amount of energy as gasoline. This can result in a decrease in fuel efficiency. So it will be unfair on the government to charge the same price for E20 petrol which has a lower energy density. Even the taxes is 18% on ethanol which is much is lower than petrol. So I hope there will be differential pricing to offset the E20 mileage impact.

Yesterday I enquired with the manager of my usual petrol pump that is a PSU dealer. He said that what they receive is nominally E10, but this ethanol blending gives the pump staff a lot of headaches. The ethanol settles down in their tank so they have to keep stirring and circulating it. So ,unless the pump is doing this frequently , we shall get a much higher percentage of ethanol if we happen to fill up when the underground reservoir is past the half empty mark.
He also said that some time back they had this sort of problem with diesel too, due to the bio ingredients that resulted in a black sludge. This has stopped now.

Regards,

Yes they should ensure availability for atleast a decade and have a color coded or similar scheme to identify, like "red" petrol for E10, "green" for E20.

When I asked a few pumps on my recent trip, they were clueless even about E10.

Government can do it. Government is doing it. In fact, it has already happened. Expecting any reduction in price is hilariously naive. This change is made a as per the interests of the sugar lobby, and the auto lobby just so happens to be a happy accomplice. That 99% cars on roads are not E20 complaint and are surely going to face issues suits their agenda. More cars coming in for maintenance, more new cars sold. More revenue for the car companies and dealers, more tax revenue for the government.

It’s not hypothetical anymore. They have openly declared that E20 will be the only grade of petrol sold after 2028.

Request MOD team to place this on the first page for updates when relevant:

As on February 2023

1) Hyundai : i10 NIOS from official page

2) Toyota : Glanza/Urban Cruiser from official statement

3) Skoda + VW : All India 2.0 cars Slavia/Kushaq/Taigun/Virtus from Autocar. In fact PM Modi flagged it off.

BMW - all (obviously petrol) vehicles :thumbs up
