function Decreasing_Fuel()
{
    for(new i=0;i<MAX_PLAYERS;i++)
     {
        if (isrefuelling[i]) continue; 
        new vid = GetPlayerVehicleID(i);
        new engine, lights, alarm, doors, bonnet, boot, objective;
        GetVehicleParamsEx(vid, engine, lights, alarm, doors, bonnet, boot, objective);
        if (GetPlayerVehicleSeat(i) == 0)
        { 
            fuel[vid] = fuel[vid] -1; 
            if (fuel[vid]<1)
            {
                fuel[vid] = 0;
                SetVehicleParamsEx(vid, 0, lights, alarm, doors, bonnet, boot, objective); 
                GameTextForPlayer(i,"~r~You are out of ~w~fuel~r~!",5000,3);
            }
        }
        new string[125];format(string,sizeof string,"Vehicle Fuel:%i",fuel[vid]); 
        TextDrawSetString(td_fuel[i],string); 
    }
    return 1;
}
