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!!!
I sure wouldn't be that's for sure.
BUT:
It doesn't matter what is unacceptable to you or me or GI or anybody else for that matter. This is an engine spec set up by the manufacture. They say it's ok for an engine to burn oil up to: (read the spec for your engine)
In the 80's it was ok for a big block Chevy to burn 1 qt/ 600 miles IIRC!! That was the spec for that engine for the time. :E
IOW's if your Expy was still under warrantee and you went to your local Ford dealer and said you wanted a new engine because yours is using 1 qt / 1000 miles they would tell you to go pound sand. And you can yell and scream and tell them you are going to sue or anything else and they will do nothing but tell you your engine is within spec.
Why?
Because that is spec for that engine. (or whatever the spec may be)
