Bioethanol fuel is a renewable fuel that is made from starch plants such as corn wheat and sugar plants. Blended with petrol, Bioethanol concentrations can be of 5% to 85% or it can be used as a direct substitute for petrol with appropriately modified engines.

90% unleaded petrol and 10% fuel ethanol blends are commonly referred to as E10 and this blend is available in many service stations throughout Australia. Those petrol stations operating under BP, Caltex, Shell and United all sell the E10 fuel blend.

Pros-
· Depending on the source and method, Bioethanol generally reduces carbon dioxide by up to 70%.

Cons-
· The 5% Bioethanol blend is only limited and sold at few outlets
· Bioethanol vehicles cost more than petrol vehicles
