2001 5.4L Super Crew. Burns 1-2 quarts every 3-5,000 miles. Truck only has 70,000 miles. Has burned oil since 30,000 miles. Great truck, but typical for American made trucks.
I would like to continue supporting the American auto industry, but I just can't afford it anymore. Too bad, aside from the engine burning oil, a clunking in the front end, vibration under the dash, it's a great truck.
I guess I'm going to keep it, no sense selling it for nothing.
I would go with a cylinder leak down test. Sounds like bad rings, if the valve seals are good. Personally, I would have parked it At 30,000 and figured it out. Got to carboned up good by now and don't know how you could ever pass inspection unless your in a state that doesn't do emission testing. Did you check mfg bulletins? What's with the clunking any ideas?

Believe it or not, it is normal for these engines to use about a quart every 2000 even when they are essentially new. Note that I said, "use", not "burn". The combination of higher compression and operating temperatures causes oil to pass through the engine. You might notice your tail pipes have a good coating on the inside. I managed to slow the process by converting to Mobil 1 0W40. I get much better performance and I only use a quart every 3500-4000.
Slide a large piece of cardboard under the truck after driving for ten minutes note in which area directly above the spot on the cardboard the oil is coming from then get under the vehicle with a drop light to look for the origin of the leak, if no leak is detected then it may be the engine is burning oil this could either be valve stem seals or broke or worn oil rings.
This is certainly one of the strangest things I have ever heard as a mechanic. . This almost sounds like some one is playing a game of letting your oil out this vehicle. With no visible leaks no burning smell of oil. However I would recommend that you check the coolant in the radiator and see if the oil is in the coolant. (If they are mixing together) If they are mixing the coolant should have a milky look to it, creamish white. If its good then the only other logical explanation is that the vehicle i s burning alot of oil, but if that was true you would see a grayish blue smoke from tail pipe. If you are 100% sure they are no oil leaks on this vehicle, then this problem is surely strange. Check coolant and get back to me. Good Luck
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.
