Shell ads banned over fuel claims
The company has been banned from using two of its adverts which promote a money-saving fuel because they have been ruled to be misleading.
A direct mailing advert, sent in March, said Shell scientists had developed a regular fuel to help consumers save money.
It said: "Their latest fuels - Shell FuelSave Unleaded and Diesel - are designed to help you save fuel and money. These advanced fuels each have a special formula enriched with Shell Efficiency Improver combined with a special detergent package - designed to improve your fuel economy from the very first fill."
The second advert, broadcast on the radio in April, told consumers that Shell could help them save fuel and money.
Three complainants challenged these claims because they believed that the adverts exaggerated the benefits available.
Shell argued that its tests showed that both the unleaded and diesel fuels achieved a 2% saving more than 10% of the time.
The Advertising Standards Authority (ASA) upheld the claims and said the adverts must not appear or be broadcast again in their current form.
Its judgment said: "The ASA noted that the ads stated that fuel savings 'may vary according to vehicle', but we considered that the claim in the ads that consumers could save up to one litre per tank at no extra cost implied that the saving would be applicable to all or most vehicles."
