There is no such thing as "Bio free diesel" as from 01/01/2011. Due to the usual bungling and meddling bunch of do-gooders that they are the european union mandarins who routinely exercise soverignity over everyone, everything and everywhere in Ireland (North and South), these european masters of the universe have decreed that we must use biodiesel. As usual, our weak self serving local political people simply tug their forelocks, bow down and say in a polite compliant voice of unison, "yes master" Contrast the differences in France, also a fully paid up member of the european union, but when it came to european union interference on the French canals, it didn't take too many seconds for the French political delegate/s to politely tell the EU where to stick their daft rulebook. And there wasn't another word about it, but until we see a new breed of politician quite unlike the CE marked ones we've currently cough up for every pay day, then you are stuck with it my friends. You will just have to get used to being treated like &^£%%$. Any of out there who run your own businesses will know all about it. It is also only a matter of time (in my opinion) until something along the lines of a boat MOT/NCT type annual test is enforced, maybe something like the "boat safety scheme" in UK mainland. The EU just cannot get enough rules. However, it has been already proved that they can be told where to get off, but alas, weakkneed yes men career politicians won't make it happen. It requires politicians AKA the French, who put country first the people second and themselves way down the list. Could it happen in Ireland ?, Not a chance!!.
