Notice that the duties on the liquified gasses are per kg, and assuming the= y are lighter than water (I believe they are, for example petrol has a Spec= ific Gravity of = about 0.8, I think) then the duty is possibly about 25% higher than it appe= ars. What's the difference between the last two? I'd have thought that red dies= el would be fuel oil rather than gas oil? I always thought there was *no* = duty on red = diesel - funny how these myths arise! :-) Is there such as thing as "red"= petrol, I wonder? It seems a right pain to pay duty for something that is= n't going to be = used in a vehicle, such as in garden equipment (mowers, strimmers, chainsaw= s) or in generators. Cheap petrol generators are easy to find, but diesel = ones seem to = be about three times the price, so to get one to use red diesel would mean = a lot of use before it pays for the difference in the running costs. I cal= culated the cost = of using a small (2kW) petrol generator as about UK=A31 per kWh, and this w= as some time ago and as we can see, about 2/3rds of this is duty that isn't= due! :-) Cheers, Howard Winter St.Albans, England -- = http://www.piclist.com PIC/SX FAQ & list archive View/change your membership options at http://mailman.mit.edu/mailman/listinfo/piclist
