At the moment petrol is between 161.9 - 163.9 and diesel around 172.9. 12-13p a litre cheaper than the UK, so I'd wait until you arrive to top up! The forecourt at Bray Hill was 161.9 yesterday as was Ramsey & Foxdale.
Amazing! never thought I'd see fuel prices reversed!!
I'm with Chrisp955, we're about 4 miles from home to digs!
(used to be about 2 until they moved to Union Mills, feels like we're going on a Grand Tour now!! )
