Always used Tesco Momentum 99 or the BP 102 when it used to be at Ethan (bloody expensive). Recently had to fill up in an emergency at Shell and noticed it was back to 99. Must say it felt more lively on Shell V Power and now earning Shell Go points. So Shell V Power 99 Just shades it over Momentum 99. My car has a full Linney Flex Fuel Kit so E85 would be ideal but that's a drive to Calais (!) or VP X85 in 19 litre drums!!!
