Yes, an interesting thread ..... BUT, have you noticed that there is a hefty difference between diesel and petrol? I mean, diesel @ 139.9 p.p.l. and petrol @ 128.9 p.p.l.? Now only a few weeks ago, in Luxembourg, diesel was 1.18 Euro per litre and petrol 1.28 Euro per litre!!!! Diesel is consistantly cheaper all over Europe! Now I know that in Holland, the annual car tax is much higher for diesel cars (and L.P.G., for that matter ) but a lower diesel price helps to keep delivery costs down and therefore shop prices. The duty is the same in the U.K. for both fuels. Distallation costs are higher for diesel and the % yield from a barrel of oil is lower than for petrol ..... maybe refinery's are not geared-up for the increasing volume of diesel cars on the roads? I just don't think that a 11p difference is justified? What do you think? Oh, I have read that the differential is going to widen over the next few years!!! Oh well, there is 15% more energy in the same volume of diesel over petrol, and £30 per year road-fund helps, too, I suppose. Still affects the ultimate economy of these cars, though!
