** SHELL REPLY (Optimax) **
Please find below the official response from our Technical Manager.
Shell Optimax is 98 RON min, it is a completely new uniquely formulated fuel in which the high octane comes from refinery blending components not octane boosting additives. It also contains a top tier detergent additive which has the ability to clean away the deposits left behind in the airways of the engine by other fuels.
All Petrol, including Optimax, is manufactured to a specification which correlates to a storage stability of 2 years when stored under correct conditions. We do not, however, recommend that it is stored for a period of more than 6 months due to the seasonal variations of the fuel. The RON of Optimax would not decrease over the period of time that the fuel remains in the tank of the vehicle or the retail site, and is only likely to decrease by 0.5 RON max under very extreme conditions.
The detergent additives contained in Shell Optimax actually dissolve the carbonaceous deposits left in the inlet valves and wash them, with the fuel, into the combustion chamber where they are burned. This additive has been tested over many millions of miles, it has been in the German market now for several years, and there is absolutely no evidence to suggest that vehicles can suffer from over use.
We have no plans to launch an additional differentiated product at present.
