At every fuel station across India · Since 2025

E20 is here. Your car may not be ready.

Three real risks — and none of them show up on day one.

Mileage drop
Ethanol carries less energy per litre. Uncalibrated engines can lose 6–7% efficiency on E20.
Corrosion & seal risk
Older fuel systems use rubber seals and metals that ethanol slowly degrades — leaks, not just inefficiency.
Warranty ambiguity
Several OEMs still haven't published an official E20 stance for older models. You're left guessing.

Illustrative sample · Scoring method v0.1

The method

One score. Four things that decide it.

Every check adds up to 100%. Bigger slices matter more — official stance and parts durability outweigh how the car is driven day to day.

Confidence first

A score is useless without the why.

Many Indian brands still haven't published a clear E20 position. We don't hide that — we show confidence, markers, and method so you can decide with eyes open.

We flag what isn't confirmedIf your OEM hasn't published an E20 stance for your exact model, you get a low-confidence flag — even when the number looks fine.
You see every marker that matteredNot a black box. Each result shows the 10 markers and their weights — so you know why the score landed where it did.
The method stays versionedEvery score is stamped with a method version (now v0.1). When India data improves, we update openly — you'll see what changed.
Questions, answered

First time? Read these first.

It depends on your OEM's published stance. Where a stance exists we surface it directly; where it doesn't, your score carries a low-confidence flag so you know it's inferred.

DriveScore is an estimate based on a documented, versioned scoring method — not an OEM certification or government advisory.
