Can I use biofuels in my car at higher concentrations than 5%?
Many vehicles can run on higher blends of both biodiesel and bioethanol. For example, Flex Fuel Vehicles can run on a mix of 85% bioethanol and 15% petrol. A number of diesel fleets are converting to use higher blends of biodiesel, for example at 20%, 30% or 50%. It is vital to check your car’s manual though, as most cars are only warrantied to work at the lower levels specified in the RTFO.
