Some people said when the warning fuel indicator lights up, their cars still could go up to 50km~80km depending on your car. My light indicator popped out before while i was on the highway, to melaka. I still could drive about 30km to the nearest petrol stop. And i only managed to pump in RM61 worth of petrol before the petrol nearly spilled out. So i guess its inaccurate. Just get to the nearest petrol stop when the warning light lights up.
