If your car is new and you did not go on highway plus you can't control your right foot properly yet, yes that's the consumption.

If you always tekan harder to move, yes, it will goes to that.

Oh...I would "advice" not to add any "extra snake oil" or pills onto your engine oil or fuel tank. At best, the price you pay for the pills could not break even on your fc, at worst, the items your pour or drop in might clog up or damage part of your engine.

Do not add any fuel saver addictives that people claim...pls get an average fc reading and dun rely on the fc reading on the meter...try to get an average reading...and ur car still quite new, current mileage berapa?
