I've been running Millie's 1.8 on regular Tesco juice almost since day one.
Very happy with what I get.
Performace, speed, power etc.
Tried, when the Tesco's stuff hasn't been available, other brands inc BP and even Jet, and must say have not noticed any difference in any of them......except the price!
