New vehicles must be E20 material-compliant
From April 2023, new vehicles sold in India were required to be E20 material-compliant. That means fuel-system materials for that cohort are rated for E20 under the national rollout timeline.
Example: a 2024 Maruti Suzuki Baleno generally falls in this window (year-based heuristic - confirm in the manual). Run make + model + year in our checker.
