E10: what's changed

When ethanol fuels were first introduced more than 10 years ago, fuel quality was unregulated and many people were not aware if their vehicle could run on E10. But a lot has changed. E10 and car engines have evolved and experts now recommend E10 fuel for compatible vehicles.

Vehicles and engines

Over the last 10 years, more motor vehicle engines have been built to run on E10 fuel. Vehicle manufacturers are constantly updating technology and fuel systems to improve performance, drivability, fuel economy and emissions.

Most petrol vehicles built since 2000 are E10 compatible. If you're unsure about your vehicle, check it's E10 OK.

Fuel economy and quality

All fuels, including E10, are now blended to strict Australian fuel quality standards. These standards set out the maximum amount of ethanol that can be blended, how E10 is labelled, the technical requirements and environmental performance of ethanol and other fuels.

E10 use around the world

Ethanol blended fuels are now used in over 64 countries around the world. Many countries have relied on ethanol blended fuel for decades. With vehicle production leaving Australia, more vehicles manufactured overseas are built to run on E10.
