My 97 never burns, leaks or uses oil, I fill it, and until the next oil
change it is still full. I use Mobile One oil and change it about every
7000.

I noticed that my '03 Mountaineer V8 is almost ready for it's 45,000 mile
oil change (I change every 5000). I also noticed that it's down a
quart...never did that before. No leaking either. Is this a potential
problem, or just normal aging?

It may be a sign that you need to change it more often.

My 99 V8 (which has the 5.0) did that around. 50k.

I rather accidently discovered oil in my PCV hoses. I realized for the
first time I had used 5w-20w oil. Went to a heavier oil, and the problem has
not returned. You might want to inspect your PCV hoses for oil - it will
"pool" in a low spot in the hose. And consider using a heavier oil and see
if it goes away.

Considering that "excessive oil consumption" is considered to be along the
lines of one quart in 800 miles, I think you're doing quite well.

If the change is as sudden as you indicate, there may be a cause for concern
but I can only offer the advice that you check the oil level at least at
every fuel fill or make it part of your weekend routine.... and see how
things transpire over the next change interval. It wasn't that many years
ago that oil change intervals were along the lines of 1000 miles and, even
on newer engines, some consumption was expected.

FWIW.... we should take a few minutes at regularly schedule intervals to
walk around our vehicles.... more often is better but even if it is only
once a month... Check lights, tire pressures, look for any tattletales....
wet spots, shiny spots, odd looking spots. Many of these may be false alarms
but if we catch a concern in it's incipient stages and act on them, we
usually can save on expenses in the long run.

I sincerely hope that everyone had a happy and safe new years eve.....

A quart in 5000 miles is not a concern. All engines consume some oil.
Those that appear not to consume oil are just replacing the oil
consumed with blow-by condensate. Sudden changes in apparent oil
consumption are often the result of taking a long trip. During normal
day to day operation it is likely that the oil never gets hot enough to
vaporize all the blow-by condensate added to the oil. When you take a
long trip, the extended period of engine opeartion allows all the
condensate to be vaporized and sucked into the intake system via the
PCV system. This makes it seem as if the engine suddenly increased its
oil consumption, when in fact nothing much has changed.

If you are still worried, a general chack of your engine for leaks is
in order. You should also make sure your PCV system is operating
properly.
