I have a 2004 pathy-same car.All paths push oil past the lifters-does not burn oil.I have to add about 1-1/2 quarts in between 3,000 mile oil changes.I check the oil when I gas up and add as needed.Hope this was helpful.

Last month, my wife complained of high gas usage as well. I suddenly remembered that I had forgotten to change the air filter the last time I did the oil change. It had been over 5 months since I'd put a new one in. So, we got a new air filter, and monitored the usage, and it was back to normal again. Maybe try this?
because of the lack of oil you could possibly have run the turbo bearings dry,the other indication will be exessive smoke/using oil.check oil level every 1k so that it dont happen again.....oil consumption should be 1pt per 750,less than 350,engine needs sorting.....
It should be minimal between oil changes. Even at 5,000 mile intervals you shouldnt see hardly any consumption. My 04 Avalanche has 88,000 and I just changed mine at 5K and didnt see any consumption. Look at the filter and drain plug on the pan and see if either of them are loose. Inspect around valve covers for leaks as well.
Unfortunately, the dealership will be a waste of time They will tell you that is normal and not to worry about it.
You can over-inflate your tires by about 8%, use a K&N air filter, drive 15 kph slower on the highway, accelerate slowly and never accelerate uphill, draft behind larger vehicles, regular maintenance (oil changes, spark plugs, wires, filters), use a fuel system cleaner every oil change. These can increase your fuel economy drastically, but if you are still noticing poor fuel economy you should have the car checked by a mechanic for what might be causing the high fuel consumption.
THE BULLETIN PERTAINS TO AN OIL CONSUMPTION PROBLEM WITH THE ENGINE. IT INVOLVES THE LEFT HAND VALVE COVER AND THE LIFTERS. THE LIFTERS ARE THE MAIN CONCERN, THEY PUMP TOO MUCH OIL AND IT GETS PUMPED INTO THE VENT HOLES IN THE PCV AREA OF THE VALVE COVER ALLOWING IT TO BE SUCKED UP INTO THE INTAKE MANIFOLD AND BURNED.
I would use 20/50 SE synthetic motor oil or high mileage or if you have the money, Amsoil is also great. Also change your filter every time and keep your oil changed about 3000 miles or so. It is overkill to change the synthetic and oil filter frequently, but will very good for your motor.
Their is a huge difference between leaking and using oil. place a large piece of carboard under the car one night and see if their is a lot of oil on the carboard the next moring. If so, try to look under the car and see if you can tel where the oil is coming from. Have the leak fixed. It might be as simple as loose bolts.
If the engine is consuming oil because it has high mileage the use regular 10w40 or even
20w40 if you are in a warmer climate. If it is using oil you cannot afford to use the high priced synthetics. These are for relitively new cars .As it uses oil just replace it with the regular 20-w40 or 10w40. To slow down consumption use STP or MOTOR HONEY.or some other oil thickening agent on the market made for worn engines.
