Shell V-Power

V-Power° is the brand name given to Shell's super-premium petrol (gasoline), formerly known as Optimax in some regions. It usually has a much higher octane rating than standard petrol at around RON (Research Octane Rating) 98; however this varies by market: In the UK, V-Power has a rating of 99 RON, while in the Republic of Ireland it is rated at 95 RON. In Australia V-Power Racing has a rating of 100 RON.

Normal premium unleaded in the UK is RON95, in Australia it is RON95 whilst in the USA, it is AKI/RdON/PON 90. The higher the Octane rating, the more the fuel resists premature ignition (see petrol for more detail). Optimax also contains detergents and other additives to clean the engine and smooth its operation. In Australia, the higher grade V-Power Racing contains 5% ethanol to boost V-Power's octane rating to 100 while reducing overall greenhouse gas load.

Shell have commenced the rebranding of Optimax in the UK to V-Power.

It was in 2004 or so that all American gas "Premium" rebranded as "V-Power°"

Commencing 18th October 2006, Shell & Coles Express will re-brand Optimax in Australia.

Optimax will become V-Power (RON 98) and Optimax Extreme will become V-Power Racing (RON 100).
