Oil -- normal usage. It has used about 1 qt per 800-1,000 miles since I've had it the last 3 1/2 years. This has not increased.

Coolant -- in the last few months, I have to fill the reservoir tank every 3-4 weeks. If not, it will begin to run hotter because, well, it is low on coolant.

Now, three things to keep in mind:
1 -- I've suspected that my aux. water pump was less than full strength but I've never had any leaks or other problems.
2 -- There is NO oil in the water, nor water in the oil. Both are clear and clean.
3 -- There are NO leaks under the car. Not oil, not coolant, not anything.

Where is the coolant going? The only thing I can suspect is that somehow the water pump loses coolant when running and since I don't let is sit still in the driveway and run all day, I don't notice the leak.

All fans work just fine. Otherwise, the car runs like a dream -- even at 191k miles.

Anyone?
