toyota GD6 bakkie

<p>I would like to find out if anyone else has the same experience as I have. I recently purchased 2 GD6 bakkies,the one I had serviced September and the other hasn't been serviced yet but both bakkies seems to be using a remarkable amount of oil. The one I had serviced started using oil at 6000km before the first service,and it started using more oil since the service. This is ridiculous as these are both brand new vehicles.</p>
