Car was topped up with Sainsbury 95 last week....whilst I have a UK car so 95 ron should be ok anyway I did notice how pants it was. Previous weeks I'd tried Tesco 99, Sains. 97 super, Shell Optimax (before V-power came in) and even Esso super.
I put in the V-Power last night and once the last dregs of sains 95 got sucked through it ran rough again but now.....wow...the car feels way smoother both on idle and acceleration. The car feels like it's got a billion bhp more.
Certainly a fuel I'd recommend to all GT4's beit UK or JDM.
