Cheapest is 1.349p (ie £1.35) for diesel and £1.25 at Asda Bromborough - all other supermarkets, are 1p more.
It'll probably be 1.35/1.26 next week.

Wonder what is making it ascend to the heavens this time?

This was taken about 8 years ago and i think it went down for a while..

Petrol 121.7 and diesel 131.7 at Asda Bromborough today.

Garage opposite the oval entrance has a neat trick. At least one of the pumps has 2 diesel and 1 super unleaded which is 10p a litre dearer than standard unleaded. Once youve pulled up its a bit awkward to try and move to another pump.

On some cars you get noticeably more mpg out of super unleaded because of the higher octane so the price balances out, also super unleaded is restricted to 5% methanol which is the limit before it damages older vehicles.

Unfortunately the premium diesels are over 20p a litre dearer than standard diesel and don't produce more power, they just have enhanced cleaners in them.

Doh, I meant ethanol not methanol.
