What fuel do you guys put in your RS models ? ... my son has just bought a '21 RS 5 and the fuel flap lists E5 and E10 but I think he'd be better off putting E5 in it.

We use Shell V-Power E5. It contains fewer additives than E10 and has a slightly higher octane rating. Used lots of different fuels over the years in two RS5’s, a TT and a couple of A6’s, and , to us, this one seems really good.

Stick with E5 and you should be good.

Shell V-Power or Tesco Momentum. If I can't get either I "splash" a few litres of other fuel in until I can load up with either of my two preferred fuels.
