A senior oil executive has predicted that oil giant Shell's new formula of diesel fuel is more environmentally friendly and gives more miles to the gallon than previous products.
John Rasmussen, UK director of retail operations at Shell, predicted that his company's new cleaner diesel product will make a welcome contribution to advances in fuel technology.
Explaining that diesel is no longer the 'dirty' fuel it once was, he sought to emphasise that technological innovations were helping combat long-term energy price rises by improving overall efficiency.
"I think the fact that CO2 emissions are better in diesel will certainly give it a better reputation in the future," Mr Rasmussen stressed.
"We are introducing a diesel which is designed to actually give the modern engine more power and keep delivering that power as the miles are clocked up.
"Of course this is done by continuously cleaning the modern injection systems that diesel engines have, and that will help them to operate at their best."
A report commissioned by Shell shows that the number of drivers using diesel has doubled in less than six years to seven million.
It predicts that there will be 16 million diesel cars on the road by 2020 as drivers look to maximise fuel efficiency.
Mr Rasmussen concluded: "I think the developments in fuel technology and car technology have improved enormously over recent years, and us introducing a new breakthrough in technology on this particular product is helping even further."
