Esso has changed the formulation of its petrol and diesel fuels with an enhanced additive package that can help provide improved engine responsiveness and clean vital engine parts when compared to standard fuels.

Motorists filling up with Esso energy petrol or diesel at the majority of Esso’s 900-branded service stations around the country will now be using fuels developed to help improve car engine responsiveness and help clean vital engine parts by removing harmful deposits from petrol intake valves and diesel fuel injectors.

Together these improvements offer motorists the prospect of a smoother-running engine with improved fuel economy and reduced emissions.

Karen Dickens, UK and Ireland fuels marketing director, said: “Esso is committed to continuous improvement to enhance the quality of our fuels, addressing evolving engine technology and consumer needs.

“We are proud of our latest generation of Esso energy fuels which can help improve fuel economy and engine responsiveness, protect against engine corrosion and clean vital engine parts.”

The launch will be backed by a major promotional campaign involving advertising, a dedicated website ( and point-of-sale materials.
