E10 Bio Unleaded

Yes. There’s no problem mixing Ampol E10 Unleaded with Ampol’s regular or Amplify premium unleaded fuel.

Many new vehicles require 95 RON premium unleaded petrol as a result of the manufacturers’ push to lower vehicle emissions by increasing engine compression ratios.

The octane level of Ampol E10 Unleaded petrol is 94 RON which although higher than regular Unleaded, is still not at the level required to prevent pre-ignition in vehicles designed for premium fuels.

Ampol E10 Unleaded is suitable for use in most new and many older cars, utes, vans, and motorcycles as indicated in the owner’s manual. However, ethanol has different solvent properties to petrol and the use of E10 Unleaded petrol may dissolve built-up residues in fuel systems in older vehicles, leading to fuel filter blocking.

Many vehicles will include a label on the inside of the fuel filler door indicating that fuels with up to 10% ethanol are suitable.

The use of E10 blends reduces tailpipe emissions of carbon monoxide (CO) and Volatile Organic Compounds (VOCs) but emissions of oxides of nitrogen (NOX) are increased. Additionally, on a full life cycle basis E10 Unleaded can have some greenhouse gas abatement benefits depending on how the ethanol is produced most ethanol currently produced in Australia will be able to demonstrate moderate levels of greenhouse gas abatement.

Ampol E10 Unleaded is a blend up to 10% ethanol and 90% regular unleaded petrol. To create Ampol E10 Unleaded petrol, the ethanol is mixed into the regular unleaded as the fuel tanker is being loaded at the fuel terminal. The quantity of ethanol introduced into the unleaded petrol stream is carefully controlled to ensure the final blend meets the requirements of the relevant Australian Fuel Quality standards.
