So a few years ago, we had some reports that cars had broken down following fueling at my local tesco. From that point I stopped buying fuel from tesco and any other supermarkets like asda, sainsburys etc. However with the cost of everything going up, I want to reconsider and stop buying from BP and shell as they cost more. What are your views and opinions regarding buying diesel from supermarkets any bad experiences or its just the same as the one found at BP shell?
