Hi all,

My Odyssey, with only about 75K miles, is going through almost 2 qts of oil
per change (every 3000m). So that is about 1 qt of oil per 1500 miles. This
seems excessive to me. The car runs fine and there is no obvious oil in the
exhaust smoke. Is this something to worry about? The dealer told me last
year that one qt per oil change was OK, but now it is getting worse....

TIA,

That's not really bad, Chuck, but you might find your PCV is stuck open
.. . . It will suck the vapour out of the crankcase like crazy and burn
it invisibly.

Our '95 ody had PCV issues too.

To bark further up the PCV valve tree--

How's the fuel mileage? Have you noticed a lot of oil on the
lower part of the engine exterior? Oil dripping on the garage
floor, maybe? There really should be none.

A malfunctioning PCV valve can reduce engine efficiency notably.
If, instead of the valve being stuck open, it's actually clogged,
then this may compromise various oil seals, allowing the oil to
leak out.

Also what kind of oil are you using. Some seem to evaporate over time.
