Maruti Baleno Zeta

Cleared the April 2023 rule: E20-safe seals, gaskets, fuel lines, pump and tank coating. The whole fuel path is rated for ethanol, so the mileage drop is about 1-2%.
What to do
Nothing to fix, nothing to budget. Fill E20 from day one.

BS6, but built two years before the material rules. On E10-era seals and lines, E20 costs about 6-7% of your mileage.
What to do
Get the fuel lines, seals and filter checked before you pay.

Nothing in this fuel system was rated for 20% ethanol. About 6-7% less mileage, roughly ₹4,000 a year more fuel at 12,000 km.
What to do
Negotiate on the 6-7% gap, or find a 2023-onwards build.

Questions, answered
First time? Read these first.
E20 is petrol blended with 20% ethanol, and it is what most Indian pumps now sell. Cars built for E10 can see fuel-line seals harden, metal parts corrode and fuel trim drift on it over time.
Nothing in a used-car transaction tells you which side of that line a car sits on. Not the listing, not the seller, not the test drive. That is the gap DriveScore fills, before you pay.
Yes, that is the whole point. You need the model, the variant and the manufacturing year, and all three are on the listing or the RC book.
You never need the keys, the seller's cooperation, or a workshop visit.
No. DriveScore combines published OEM declarations, where they exist, with a documented rules engine based on manufacturing era and variant.
It is an informed estimate to shortlist and negotiate with, not a certification or a government advisory.
Manufacturing year. Fuel-system materials and engine calibration changed across BS4, BS6 and the April 2023 E20 material mandate, so a 2019 and a 2023 of the same model are not the same car for this purpose.
It is the single biggest lever on the score, and it is the one thing a listing always tells you.
We fall back to manufacturing date and variant-family inference, and mark the result low confidence.
You will see exactly which markers were inferred rather than confirmed, so you know how much weight the number deserves.
Not necessarily. An Avoid is a price and a plan, not a dead end.
The report names the markers that pulled the score down, what living with them or fixing them actually involves, and whether a later manufacturing year of the same model clears them. Plenty of buyers use it to negotiate instead of walking.
On most used cars the original warranty has already run out, so it rarely bites.
Where a car is still covered, it comes down to the manufacturer's published stance. Where one exists we surface it directly; where it does not, the score carries a low-confidence flag so you know it was inferred.
It can. The scoring method is versioned, currently v0.1, and every result is stamped with the version it came from.
When markers or weights improve, cars are re-scored under the new version and you are told what changed. Nothing moves silently.
Only the model, variant and manufacturing year of the car you are looking at. Nothing about you, and nothing about whoever owns it.
We do not sell or share what you check, and we never contact the seller.
