My interpretation is that Shell's claims are less bold, being focussed more on engine cleanliness as a means of maintaining optimum performance (which is hard to dispute), whereas BP go further with their claims of extra power, economy and reduced emissions and particulates based on independent testing by MIRA. In practice both fuels exhibit the same benefits, but BP should be applauded for publishing their results.
