How Much Oil Do you Use?

Too many responses to go one by one, so I'll try this.  And thanks all for 
the info.

Well, one things clear, my car is using more than the average amount of 
oil/mile.  So now I've got to wonder why.  I can't imagine I'm the only 
person on this list who's explored the nether regions of the tachometer.  
Oil changes w/dino juice every 5k or so.  Not aware of overheat issues.  Use 
Mahn/VW filters.  Replace the air filter regularly with not Fram.

I spoke with a local shop about stem seals, the reason I thought about 
guides and seals is they had recently done the job on another 20v, and found 
the car was still consuming oil after replacing just stem seals.  This 
situation was cured by guide replacement.  I picture a really fun part about 
the head removal being the exhaust studs.

The cost for the work would buy a lot of oil.  Assuming consumption stays 
constant, and based on a conservative $500 cost from the machine shop, at 2$ 
a quart, it would take oh, about 375k miles to break even.  Any other beny's 
from head work?  Maybe I'll get a leak down test to pinpoint culprits.

Well, life goes on, and the oil keeps flowing (insert politcal comment 
here), so I'll keep drivin.
