Truck still under warranty but they say it's normal to put oil between oil change . If I don t put oil between change its gets so low that it fall on 2 cylinders Every 1000 km I would go to the garage so they check the oil They did that for about 5000 km, in that period the oil went down below the add on the stick, they told me they send that to Chrysler and there nothing they can do about it . If I have to put oil every time I go to the store I might as well walk to the store it will be cheaper for me.
