The use of fossil fuels for transportation purposes has increased significantly over the last 60 years, and the environmental effects of the use of fossil fuels have become a matter of concern in recent years. This has lead to the development of a number of fuels which are intended to reduce the environmental impact of the ever-growing use of motor vehicles. There are a number of views on the advantages and disadvantages of these fuels, such as dispute as to the life-cycle emissions and the impact on performance. It is the aim of this paper to present independent findings into the performance and emissions pros and cons for some alternative fuels, Regular Unleaded (91octane), Premium Unleaded (95 octane) and Premium Unleaded, Ultimate (98 octane). In a full scale laboratory testing undertaken at Central Queensland University, it is found that Premium Unleaded and the Ultimate offer better power and torque efficiency with a grater [sic] percentage of specific fuel consumption compared to regular unleaded petrol. Moreover, the Ultimate appeared to have less exhaust emissions with lower concentration of all pollutants compared to regular unleaded petrol.
