Losing oil
If you are not seeing any leaks underneath (puddles on the ground), you are probably burning it out the exhaust. Could be due to stuck rings. I was having this issue with my 08 Aspen when I got it. Would burn through a quart of Amsoil every 600-800 miles. Dealer tried to tell me this was normal. None of my other vehicles would loose oil at this rate and I drive them all hard. My 95' Ranger had over 330k miles on original motor and trans and never burned at this rate.
I switched to Castrol High Mileage oil with a bottle of STP treatment in the blue bottle and now get 1300-1500 before having to add any. Also be sure to use the recommended 5w-20 weight. Any thicker will cause issues with the MDS and any thinner will seep past rings and burn.
