Tesco has launched a major fuel price offensive against its rivals, offering customers up to 50p off per litre based on their purchases in store on a range of food and non-food items.

The deal – which Tesco claims will enable some customers to fill their tanks at 2008 prices – includes a number of kitchen staples and household essentials, including Heinz Tomato Ketchup and Andrex toilet paper.

Customers will receive a 10ppl discount voucher with each product purchased but can boost that to 50p off if they buy any combination of five products or deals.

“Most significantly, up to five 10ppl vouchers can be used at the same time at our petrol filling stations,” said David Wood, Tesco’s UK marketing director.

“This means Tesco customers who take full advantage of this promotion will save 50p on every litre of fuel they buy on our forecourts and they will enjoy the lowest fuel prices by far anywhere in the UK,” he added.

The coupon blitz, which runs from today until 1 August, comes as Tesco steps on the gas with its coupon promotions.

Last week it launched an offer giving customers spending £20 in store the chance to get £5 off their next shop of £40 or more.
