Autoini.com – Indonesia is advancing its adoption of ethanol-blended gasoline (bensin campuran etanol) to support renewable energy and reduce emissions. The government has planned a phased approach: starting with E5 in 2026 and moving toward E10 by 2030. This strategy aims to improve air quality, reduce fossil fuel dependence, and strengthen the local bioethanol industry.
Ethanol Mix Policies & Timeline for Indonesia
- Mandatory E5 gasoline starting 2026 – Initial rollout on Java Island, expanding nationwide.
- Target E10 gasoline by 2030 – Under Ministerial Regulation No. 32/2008.
- Fuel-grade ethanol production target – 1.2 million kilolitres/year by 2030 from sugarcane, cassava, and palm sugar.
- Current production is limited: only 3 of 13 sugar and supporting industries meet fuel-grade standards (~60,000 kilolitres/year).
Implementation Examples & Early Steps
- Pertamina’s Pertamax Green 95 – 5% ethanol available at select stations in Jakarta and Surabaya.
- Proposed higher blends – Mixing Pertalite (~90-RON) with ~7% ethanol (potential “Pertamax Green 92”), currently under study.

Ethanol Fuel – Benefits & Motivations
- Reduces dependence on imported fossil fuels.
- Improves air quality and lowers greenhouse gas emissions.
- Supports local agriculture and bioethanol production.
- Raises octane and reduces engine knocking in premium fuels.
Ethanol Fuel Challenges & Risks
- Limited fuel-grade ethanol supply vs future demand.
- Infrastructure and logistics for blending, storage, and distribution need upgrades.
- Vehicle compatibility issues for older cars (corrosion, seal wear, reduced mileage).
Ethanol Fuel Imapct Indonesia
- Modern cars & bikes (post-2010) – Safe with E5, minor performance or mileage changes possible.
- Older vehicles – Potential fuel system wear or corrosion if used long term.
- Premium fuels (RON 95/92) – Ethanol raises octane and reduces knocking; careful quality control required.

What’s the Plan vs. What’s Already Happening
| Component | Plan / Target | Current Status |
|---|---|---|
| Mandatory E5 gasoline | Start 2026 (Java first → nationwide) | Partial implementation: Pertamax Green 95 with 5% ethanol in Jakarta & Surabaya |
| Increase to E10 | By 2030 | Under regulation revision; not yet fully implemented |
| Ethanol production | 1.2 million kilolitres/year by 2030 | Currently only ~60,000 kilolitres/year from qualified producers |
| New fuel types (higher octane blends) | Pertalite / Pertamax Green 92 with ~7% ethanol | Proposed; under study, not yet widely launched |
Ethanol Fuel – Summary
- 2026: Mandatory E5 rollout in Java, expanding nationwide.
- 2030: National adoption of E10 target.
- Support includes ethanol production expansion, supply chain development, and infrastructure upgrades.
- Pilots like Pertamax Green 95 are already testing feasibility and vehicle compatibility.
FAQs – Ethanol Fuel
What is the timeline for ethanol-blended gasoline in Indonesia?
E5 is planned from 2026 (Java first), with nationwide expansion. E10 adoption is targeted by 2030.
Is E5 safe for my car or bike?
Modern vehicles (post-2010) are generally compatible. Older vehicles may experience minor wear or reduced mileage over time.
Why is Indonesia switching to ethanol-blended fuels?
To reduce fossil fuel imports, lower greenhouse gas emissions, and support local agriculture and ethanol production.
Will ethanol gasoline reduce fuel efficiency?
Slightly. E5 may have negligible impact; E10 could reduce mileage by 5–10% in non-flex-fuel vehicles.
Which fuels are being tested for higher ethanol blends?
Pertalite and premium gasoline (RON 92/95) are being tested with ~7% ethanol, potentially marketed as “Pertamax Green 92.”
