Commonly asked Questions and Answers

What is Ethanol?
Ethanol is a non-fossil fuel that is produced from a variety of agricultural crops such as sugar cane and grains.

How much ethanol will be present in Mobil E10 Unleaded?
Mobil E10 Unleaded will contain up to 10% ethanol blended with unleaded petrol.  The Australian government has limited the amount of ethanol in petrol to 10%, or ‘E10’.

Mobil E10 Unleaded fully complies with Australian Fuels Quality Standards and supports Mobil’s proud history of supplying high-quality fuels that you can trust.

Is Mobil E10 Unleaded suitable for my car?
Most cars built after 1986 are compatible with fuel blended with up to 10% ethanol whereas many pre-1986 vehicles are not. We recommend that you follow your vehicle manufacturer’s advice. The Federal Chamber of Automotive Industries (FCAI) website www.autoindustries.com.au/ethanol contains a comprehensive list of vehicles capable of operating on ethanol blends up to a maximum of 10% ethanol.   If you are unsure about your particular model, you should consult your vehicle’s handbook or manufacturer.

The FCAI website includes a list of manufacturer contacts. If you own a pre-1986 vehicle and you currently use an antivalve seat recession additive with your petrol, we recommend that you continue to do so with Mobil E10 Unleaded.

Can I switch between Mobil E10 Unleaded and other grades of Mobil petrol?
Yes. If you currently use an anti-valve seat recession additive with your petrol, we recommend that you continue to do so with Mobil E10 Unleaded.

Ethanol is a high-quality, high-octane fuel component. The octane in Mobil E10 Unleaded is typically above 93 RON whereas regular unleaded petrol is 91 to 92 RON.
