Diesel drivers get worst fuel deal
The average price of petrol in the UK has risen from 133.35p a litre to 134.61p, while diesel has gone up from 138.17p a litre to 139.16p. Over in Northern Ireland, petrol is the most expensive with London having the cheapest.
The same goes for diesel, with Northern Irish paying 139.8p a litre and London and the south west paying out 139.1p.
The AA warned that this year, retailers have on average been "creaming up to £1 a tank extra off diesel car drivers and up to £1.40 a tank extra off diesel van owners", adding; "at present, the 1p-a-litre premium that fuel stations are generally adding to the cost of diesel adds 5,500 miles to the break-even point for a new car buyer who chooses diesel instead of petrol."
"Diesel cars typically cost £1,500 more but the saving from better fuel efficiency should eventually recoup that."
AA president Edmund King said: "To be fair, there is often much greater variation in the price of diesel among retailers in a town than with petrol. However, on average, the profit margin on diesel is consistently at least a penny higher than with petrol."
"The clear message to diesel drivers is to take advantage of the greater range of prices locally. Some forecourts are more diesel-friendly than others."
