BP has rolled out what it describes as its biggest fuel launch in the UK in 10 years.

Drivers in the UK can now fill up with new BP Ultimate which includes active technology, a formula designed to actively fight dirt, protect against it building up and so help engines run as the manufacturer intended.

BP says the cleaning action can give drivers up to 21 extra miles per tank, and drivers who achieve improved fuel efficiency through use of Ultimate fuels may also reduce their CO2 equivalent emissions by up to 4%.
