the panda really make me tao kongkong!

I got the car in September, tried 3 tanks of M'sia V-power near border, all 3 tanks gave me 10.2km/L, 10.5km/L, 10.7km/L, not sure why also. Perhaps the petrol really kena mixed

then I tried SPC 95 for next 3 tanks, my FC becomes 12.1km/L, 12.7km/L 13.2/L. My driving style always the same, no hard revving or wild overtaking.
If RON92 really wun spoilt the engine, then might as well save the $. A penny save is a penny earned...
