Always used Applegreen for diesel (bog standard B7 to EN590, not the premium stuff) and never had a problem with it but I do change the fuel filters in accordance with manufacturer specifications - every 90,000 kilos for my Octys.
I've recently started using Certa in the taxi 'cos it's cheaper and you get Tesco Clubcard points with it - also bog standard B7 to EN590. I hope it proves as reliable as the Applegreen stuff... getting the same kilometerage so far anyway.
