I only go to Shell and use their V Power for the Mog
Only because I have a very good friend who is a architect that just specialises in roadside developments which is mainly fuel stations and he works for all the big retailers and he told me years ago that only Shell have replaced all their underground tanks with new moisture free tanks so there is a low risk of any water in the fuel
It might be different now and all the other retailers might well have now upgraded but I’m sticking to Shell V Power
