diesel fuel does your car run better on different fuels

hi see the petrol heads had a thread going about how they perform with different makes of fuel. I don't beleave that it makes much difference with petrol. Now diesel is a different thing.i read here some use Asda some Tesco some only shell. do you find that much difference as the fuel must be to of a standard or would it be down to poorhouse keeping (water,crap) in with it.in this country we only got 50ppm four years ago before then had a drain pipe on my filter as always getting warning light up. Any way lets hear from you all lol
