Do not accept current E20 pricing as fair
Based on 497 completed responses. Public opinion study.
What we set out to answer, and what we found
We tested whether India E20 rollout has earned consumer trust
How aware are motorists, and what are they driving?
We measured awareness of the E20 mandate and whether respondents' vehicles were bought before or after the 2023 compliance cut-off.
What is it doing to vehicles?
We asked whether owners had noticed specific issues since the rollout, from mileage drops to engine knocking and stalling, and how they rate E20 quality.
Does the price feel fair?
We asked what they think of current E20 pricing, what discount they would see as fair, and whether they would pay a premium to avoid ethanol entirely.
Who do people think benefits?
We asked who benefits most from the mandate and whether politicians are seen to be profiting.
Technical friction is widespread. 62.4% report specific vehicle grievances since the rollout, led by a drop in mileage (33.0%), loss of engine power (29.2%) and engine knocking (28.8%). Only 18.7% report no issues.
Many would pay to avoid ethanol. 73.0% would pay a premium for pure petrol (0% ethanol) at a separate nozzle, and 66.6% would sign a petition for multiple ethanol blend options at the pump.
Most motorists reject the price. 77.5% reject current E20 pricing. 31.0% say it should be significantly cheaper than pure petrol, 26.0% call it overpriced for the lower mileage and 20.5% call it a hidden tax. 83.4% want a discount.
High awareness means close scrutiny. 74.4% rate their awareness of the mandate 4 or 5 out of 5, so engine stalls and mileage dips are now blamed directly on the fuel.
36 to 45 year olds are the most critical group. They report the highest rate of engine knocking (43.2%) and the strongest suspicion of political profiteering, though the base is only 44 respondents.
Trust in the policy is weak. 58.6% agree politicians are financially benefiting from the shift, and only 33.0% see it as a genuine environmental move.

Premium for 0% ethanol at a separate nozzle
High Awareness Makes E20 a High-Scrutiny Issue
Respondents rated their awareness of the government mandate to move all petrol to a 20% ethanol blend, and said when their primary vehicle was bought.

|---|---|
| During or after 2023 (likely E20 compliant) | 43.7% |
| Before 2023 (likely not compliant) | 37% |
| Not sure about compliance | 19.3% |
01. 74.4% rate their awareness of the mandate high or very high, and only 9.4% rate it low. Mechanical problems are now linked to the policy and not put down to maintenance.
02. 50% of 36 to 45 year olds report maximum awareness, against 31.5% of 18 to 24 year olds.
03. 37.0% drive older, likely non-compliant vehicles and 19.3% are unsure of their status, so more than half the fleet is open to grievances or confusion. Two-wheelers are the main commute vehicle for 53.5%.
62.4% Report Vehicle Grievances Since the Rollout
Respondents said which issues, if any, they have noticed with their vehicle since the rollout of ethanol-blended petrol. Multiple answers were allowed.

| 4 of 5 | 35.4% |
| 3 of 5 | 19.5% |
| 2 of 5 | 8.3% |
| 1 of 5 | 3.4% |
01. 62.4% report at least one specific mechanical grievance, led by a drop in mileage (33.0%), loss of engine power (29.2%), engine knocking (28.8%) and stalling (27.6%). Only 18.7% report no issues.
02. 36 to 45 year olds report engine knocking at 43.2%, against 25.4% of 18 to 24 year olds. That may reflect older vehicles or more attention to engine health. The report notes the age difference is not statistically significant overall.
03. Oddly, 68.8% rate E20 quality 4 or 5 out of 5 compared with pure petrol, and only 11.6% rate it 1 or 2.

|---|---|
| Should be significantly cheaper than pure petrol | 31% |
| Overpriced for the lower mileage it provides | 26% |

Fair Price for E20 Compared With Pure Petrol

View the data behind this chart
| Answer | Share |
|---|---|
| ₹15 to ₹20 cheaper per litre | 36% |
| ₹5 to ₹10 cheaper per litre | 26.7% |
| Half the price of pure petrol | 20.8% |
| Same as current price | 16.6% |
01. Only 22.5% accept current pricing as fair. 31.0% say E20 should be significantly cheaper than pure petrol, 26.0% call it overpriced for the lower mileage, and 20.5% call it a hidden tax.
02. 83.4% want a discount. The largest group (36.0%) expects ₹15 to ₹20 off per litre, and 20.8% think it should cost half as much as pure petrol.
03. The report points to a mismatch between quality and price. 68.8% rate the quality high, yet 77.5% reject the price, because the blend is seen as cheaper to produce but sold at premium rates.
58.6% Suspect Politicians Are Profiting

| National economy (lower oil import bill) | 21.7% |
01. 58.6% agree that politicians are financially benefiting, and 27.4% strongly agree. That is nearly double the 16.1% who disagree. Among 36 to 45 year olds, 68.2% agree.
02. The environmental case is not convincing most people. Only 33.0% see the policy as a genuine environmental move (9.1% strongly), while 37.6% disagree and 29.4% are neutral.
03. Only 21.7% name the national economy as a primary beneficiary. 33.0% name government profit margins or tax revenue and 28.2% name politicians with biofuel interests.
04. About one in four chose neutral on both statements. That middle group could turn against the policy if technical issues spread.

Would Sign a Petition for Multiple Ethanol Blend Options
Base: 497 respondents

| Answer | Share |
|---|---|
| Yes, I support the petition | 66.6% |
| No, I am fine with the current mandate | 33.4% |
01. 73.0% would pay a premium for pure petrol (0% ethanol) at a separate nozzle. The figure rises to 78.4% among 25 to 35 year olds, against 68.2% of 36 to 45 year olds.
02. 66.6% would sign a petition demanding multiple ethanol blend options at fuel stations.
03. On the preferred fuel ranking, pure petrol (68.6%) and flex fuel E85 (69.4%) take the highest first-place shares among those who ranked each option. E20 is competitive only at a discount and still trails pure petrol on average rank (1.61 against 1.58).
E20 Concerns Are Pushing Motorists Towards EVs
Respondents rated how likely they are to consider switching to an electric vehicle because of concerns about E20 fuel quality and vehicle life.
Likelihood of Switching to an EV Over E20 Concerns
Base: 497 respondents, rated 1 to 5
View the data behind this chart
| Answer | Share |
|---|---|
| 5 of 5 | 34.6% |
| 4 of 5 | 40.8% |
| 3 of 5 | 16.1% |
| 2 of 5 | 6.2% |
| 1 of 5 | 2.2% |
01. 75.4% rate their likelihood of switching to an EV because of E20 concerns at 4 or 5 out of 5, and 34.6% give the maximum. Among 36 to 45 year olds, 50.0% give a 5, against 31.5% of 18 to 24 year olds.
02. Of 494 respondents, 300 (61%) gave 4 or 5 both to E20 quality and to EV switching, a relationship the report calls statistically significant.
03. Newer vehicles, supposedly compliant (bought in or after 2023), draw more reports of power loss (70 against 57) and stalling (63 against 56) than older vehicles. Mileage-drop reports are the same for both (70 each).
What we would recommend
Practical priorities drawn from this study for further validation.
Offer a zero-ethanol premium tier.
73.0% would pay a premium for pure petrol at a separate nozzle, and 66.6% want multiple blend options. A clearly branded, non-blended premium fuel can serve that demand.
Publish open performance tests for two-wheelers.
Two-wheelers carry 53.5% of daily commuters, and 62.4% of motorists report vehicle issues. Open testing gives data-backed reassurance on mileage and engine health.
Deal with the hidden-tax perception through clear pricing.
77.5% reject current pricing and 83.4% expect a discount. Bring E20 pricing closer to its perceived value, or offer loyalty incentives that offset the reported technical problems.
Rebuild trust by talking about consumer protection.
58.6% suspect politicians are profiting and only 33.0% see a genuine environmental move. Brands should focus communications on consumer and engine protection, backed by third-party verified data, and not on government compliance.
