Can I run my car on E10 fuel?

NSW is leading the way towards replacing regular unleaded with E10, but not all cars are compatible.

That's the question owners are asking as state governments move towards making ethanol blends mandatory.

NSW is leading the push. Already the law in that state requires oil companies to blend six per cent ethanol in the regular unleaded fuel they produce. That will rise to 10 per cent on July 1, 2011, when regular unleaded will be banned. Owners currently using regular unleaded have the choice to use E10 or the more expensive Premium unleaded.

As a rule of thumb most cars built in the last 10 years or so can use E10 without any problem, although some carmakers whose cars run on PULP specify the use of high-octane fuel, which calls into question the use of E10 because of its maximum 94-octane rating.

Older cars should not use E10, as it can have a devastating affect on gaskets, seals, hoses and other rubber components in the fuel system.
