More Performance:Less Pollution
Dear Gary
Thank you for your query received in this office regarding BP Ultimate fuel.
The RON (Research Octane Number) for BP Ultimate Unleaded is guaranteed 97. For Performance vehicles it is also helpful to know the MON (Motor Octane Number). This is where the Antiknock quality is tested at full throttle and High engine speed, and part throttle and low&high engine speeds. The MON for Ultimate Unleaded is guaranteed 86, however it is typically higher, upto 87.5.
BP Ultimate burns more efficiently and cleans your engine as you drive to deliver sharper acceleration and improved responsiveness while producing less harmful emissions. Compared with ordinary unleaded, the benefits of BP Ultimate come from the properties of both the base fuel and a number of other special components added to the formulation. However, don’t forget that BP Ultimate is the name for two new fuels - one diesel and one unleaded and the formulations for each are different.
Thank you for your interest in our new advanced fuels.
Yours Sincerely
BP Customer Care
