Shell has teamed up with Andrew ’Freddie’ Flintoff to launch Shell FuelSave unleaded and diesel described

as two breakthrough fuels designed to help drivers save up to 1-litre of fuel per tank from the very first fill, at no extra cost. The company says the new smarter fuels are a breakthrough in fuels technology and contain Shell’s most advanced fuel economy formula to date. They will replace regular Shell unleaded and Shell diesel, with Shell claiming to be the first company in the UK to offer customers a fuel that can help vehicles to be more fuel efficient, without having to pay any more. To help lead the nation in driving fuel efficiently, Shell has challenged Ashes hero, Freddie, to train motorists via a specially-designed course of online fuel saving tips available at People can learn how to save fuel as well as money, plus register for the chance to win free fuel for a year. Freddie said: "I had no idea that by using the right fuel and making a few simple changes to my driving habits, I could be so much more fuel efficient." Shell said the innovation behind the new fuels is in the in-built efficiency improvers. In the case of Shell FuelSave unleaded, these combine to reduce energy losses by lubricating parts of the engine where oils are less effective. For Shell FuelSave diesel, it is designed to ignite and burn more effectively than regular diesel, which helps lead to more effective combustion in the engine.
