India is on an aggressive path to cleaner mobility, and one of the biggest shifts in this journey is the adoption of E20 fuel, petrol blended with 20% ethanol. The central government has mandated that by 2025, fuel retailers across the country must offer E20 petrol, and all new vehicles sold should be compatible with it. This means every carmaker, including Maruti Suzuki, has had to ensure its line-up is ready for this transition.
Maruti Suzuki, India’s largest carmaker, has taken a proactive approach. In April 2023, the company announced that its entire petrol line-up is now E20 compliant, coinciding with the shift to BS6 Phase 2 emission norms. This means that every new Maruti Suzuki petrol car manufactured from April 2023 onwards is designed to run safely on E20 fuel.
For owners of older models, the picture is mixed. Maruti has indicated that it will offer upgrade kits for certain cars to make them compatible with higher ethanol blends, though these may be limited to relatively newer models.

What is E20 fuel?
E20 fuel is petrol blended with 20% ethanol and 80% petrol. Ethanol is an alcohol produced from crops such as sugarcane, corn, and rice husk. It is renewable, biodegradable, and helps reduce dependence on crude oil imports.
Compared to pure petrol, ethanol has a higher octane rating but a lower energy density, which can slightly reduce fuel efficiency. It also absorbs more moisture, making non-compatible rubber, plastic, and metal parts prone to faster wear.
India has already moved from E5 to E10 blends across fuel stations. The government’s target is to make E20 widely available by 2025, cutting emissions and supporting farmers by boosting demand for ethanol feedstock. Automakers, including Maruti Suzuki, have now updated their vehicle line-ups to ensure safe usage of this new blend.
Maruti Suzuki Cars Compatible with E20 Fuel
Maruti Suzuki officially confirmed that from April 2023 onwards, all petrol models sold in India are E20-compliant, coinciding with the BS6 Phase 2 update. This means the entire range, hatchbacks, sedans, SUVs, and MPVs, can safely run on 20% ethanol-blended petrol without affecting warranty or drivability.
For older vehicles, Maruti has indicated that upgrade kits may be offered for select models, but widespread rollout details are still limited. Owners of pre-2023 cars should check with dealers before using E20 fuel.

How to Check if Your Maruti Car is E20-Compatible?
While all Maruti Suzuki petrol cars manufactured from April 2023 onwards are E20-compliant, owners of older vehicles may want to confirm before refueling with higher ethanol blends. Here are four reliable ways to check:
- Owner’s Manual – Every Maruti car manual specifies the type of fuel recommended. Post-2023 editions clearly mention E20 compatibility.
- Fuel Lid Sticker – Many E20-ready cars have a label near the fuel cap or inside the lid indicating “E20” or “E20/E10 petrol.”
- Dealership Confirmation – Authorised Maruti Suzuki dealers can check your VIN (Vehicle Identification Number) and confirm whether your car is certified for E20 fuel.
- Official Website & Press Releases – Maruti’s official announcements (2023 onwards) confirm E20 compliance for the entire lineup, but checking model-specific details online ensures accuracy.
For cars manufactured before April 2023, compatibility depends on whether Maruti releases official upgrade kits. Until then, these vehicles should primarily use E10 petrol to avoid performance or warranty issues.
Impact of E20 on Maruti Cars
Shifting to E20 fuel comes with both advantages and considerations for Maruti Suzuki owners.
- Mileage: Ethanol has lower energy density than petrol, so a small drop in fuel efficiency (≈2-4%) is expected compared to E10. Maruti has calibrated its engines from April 2023 onwards to minimise this gap.
- Performance: E20 has a higher octane rating, which helps reduce knocking. In compliant Maruti engines, performance differences are negligible for daily driving.
- Engine Wear & Maintenance: Ethanol can corrode non-compatible rubber and plastic parts, but Maruti’s updated E20-ready models use resistant materials. For pre-2023 cars, using E20 may risk premature wear if not officially upgraded.
- Resale Value: Buyers are more likely to prefer E20-compliant cars since India is moving fully to this blend by 2025. Owning a compliant Maruti could maintain better resale value compared to older, non-certified models.
Summary
India’s transition to E20 fuel by 2025 is a major step toward cleaner mobility and energy security. For car owners, compatibility plays a crucial role in maintaining performance, fuel efficiency, and warranty coverage.
Maruti Suzuki has taken the lead by ensuring that all petrol models manufactured from April 2023 onwards are E20-ready. From hatchbacks like the Alto K10 and Baleno to SUVs like the Brezza and Grand Vitara, every new Maruti can safely run on 20% ethanol-blended petrol. Owners of older cars should consult dealers about upgrade kits or continue with E10 until official options are available.
With the brand’s proactive stance, Maruti owners can drive confidently into India’s ethanol-blended future.
FAQs About Maruti Suzuki E20 Compatibility
1. What is E20 fuel, and when will it be available across India?
E20 fuel is petrol blended with 20% ethanol. The Indian government plans to make it widely available from 2025 onwards, with many stations already beginning phased rollouts.
2. Are all Maruti Suzuki cars E20-compatible?
All petrol Maruti Suzuki models manufactured from April 2023 onwards are E20-ready. Older models may need upgrade kits, which Maruti has indicated will be offered selectively.
3. Will using E20 fuel affect my car’s mileage?
Yes, mileage may drop slightly (≈2-4%) since ethanol has lower energy content than pure petrol. Maruti has calibrated engines in compliant models to minimise this impact.
4. Does using E20 void my Maruti car’s warranty?
No. For models built from April 2023 onwards, using E20 is covered under the standard warranty. For older models not certified, using E20 could risk warranty claims.
5. How can I check if my Maruti car is E20-ready?
You can confirm via your owner’s manual, fuel lid sticker, dealership check, or Maruti Suzuki’s official website/press releases. These are the most reliable ways to know your car’s compatibility.
