Quite some time back Honest John (Daily Telegraph) was pretty scathing about supermarket petrol - I made the mistake of putting one tankful into my previous Porsche, took 2 tanks of Texaco clean system to get her back to rights. When I bought my C270 18 months ago (my first diesel since about 1985) I emailed him to ask if he had the same opinion of supermarket diesel. His reply was "it depends on where it comes from". Since then I've used a mixture of Tesco and Shell (depending on whether I've got a 5p/litre discount voucher!) and not noticed any difference whichever fuel I've used.
