where did the oil go?

You didn't read my post! I said it should not burn oil. But if it does nothing more than a half quart in 3k miles. Anything more and it should be taken care of. And yes working hard it could also use some oil. Again nothing more than a half quart.

You, sir, are absolutely wrong on this one. The engineers at Ford didn't just pull the number out of thin air. I can assure you that they know best what is considered 'normal' for the OP's engine and what's considered excessive. As I already cited, it's one quart every 900 miles.

Here's the exact text from the proverbial horse's mouth:

Oil Consumption Test

The following diagnostic procedure is used to determine the source of excessive internal oil consumption.

NOTE: Oil use is normally greater during the first 16,100 km (10,000 miles) of service. As mileage increases, oil use generally decreases. Vehicles in normal service should get at least 1,450 km per liter (900 miles per quart) after 16,000 km (10,000 miles) of service. High speed driving, towing, high ambient temperature and other factors may result in greater oil use.

And you would be perfectly fine with using upwards of 5 quarts of oil between oil changes for the life of the vehicle? when the majority of vehicles are using none!!!

First I seriosly doubt the "majority" of engines use no oil between changes, the vast majority will use some. I have NEVER had an engine that used NO oil between changes even when the change interval was 3,000 miles. How much is the question, many were/are a quart or less in 3,000+ miles, but ALL used some amount.

Second if you have an engine that uses no oil between changes you are living in a dream world. What you are experiencing is fuel dilution in the oil. SOME oil is being used, no quesiton. If the oil level doesn't change at all, your getting fuel dilution in the oil making p for the lost oil, and THAT is a much bigger problem than using some oil!
