For almost 15 years, petrol was cheaper than diesel. But this summer, for two months only the cost of diesel at the pump dropped below its counterpart.
Now though, the price of unleaded has dropped again. And diesel is once more the more expensive fuel.
Andrew Pate went to find out why - and what it means for us motorists here in the South.
Like the stuff itself, petrol and diesel prices are volatile. And whether you drive or not, your life is affected by them. When the cost of a litre started to skyrocket some years ago, freight organisations and drivers groups said it couldn't go on.
Well it hasn't - and much to many people's surprise, petrol's almost below a pound a litre - and according to the boss of Shell, prices will stay low for months. But what does this mean for companies, and consumers, around the south-east? David Johns has been finding out.
At 11.59am on Sunday 12 October, the offender dispensed £81.51 of diesel into their silver Range Rover BO64 BZS and left the forecourt without making payment.
Police are particularly interested in identifying the male shown in these CCTV images.

Driving will cost less for thousands across the south as supermarkets cut their fuel prices.
Asda, Sainsbury's and Tesco are today reducing the cost of their petrol and diesel by 2p a litre.
In Asda's case, the reduction means its customers will pay no more than 126.7p a litre for petrol, with diesel being 129.7p a litre - its lowest price since January 2011.
Asda said a strengthening pound against the dollar had been the key driver behind the cuts.
The AA said average UK petrol prices fell to 131.12p a litre, with diesel down to 135.38p this weekend.

Petrol prices - according to the AA - are forcing drivers off the road. A litre of unleaded has gone more than six pence a litre since the begining of the year and many families and companies are struggling with the cost. Fred and Sangeeta link to Kerry Swain.
