Frequently Asked Questions
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.
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.
