Be,
It's my guess that the the rings are starting to wear. A compression check
during the next scheduled oil change service should reveal any serious
problems related to the rings. You may also want to have a tune-up in case
the valves, timing, etc need to be adjusted. If you have a oil change and
the oil becomes black within two weeks--that could be a sign of a bad head
gasket. I advise you to check the oil about once a week in order to check
the level and the color of the oil. Keep a record of the results.

if they were an experienced professional, they'd know that a broken top
ring makes the most difference to compression [and little difference to
oil consumption], the second ring, much less to compression [and a
reasonable difference to oil consumption], and the oil control rings,
none at all to compression, [but a whole ship-load to oil consumption].
since oil loss is the the problem, and lack of compression apparently
not, what conclusions do you draw here about the efficacy of a
compression test here jason? hint: the professional mechanics' actions

dude, compression can vary quite a lot from cylinder to cylinder, and
the engine still be perfectly serviceable with little oil consumption.
i respectfully suggest you either get some training and experience under
your belt OR you stick to topics you actually /do/ know about. thanks.

if they were an experienced professional, they'd know that a broken top
ring makes the most difference to compression [and little difference to
oil consumption], the second ring, much less to compression [and a
reasonable difference to oil consumption], and the oil control rings,
none at all to compression, [but a whole ship-load to oil consumption].
since oil loss is the the problem, and lack of compression apparently
not, what conclusions do you draw here about the efficacy of a
compression test here jason? hint: the professional mechanics' actions
here should give you a clue.

dude, compression can vary quite a lot from cylinder to cylinder, and
the engine still be perfectly serviceable with little oil consumption.
i respectfully suggest you either get some training and experience under
your belt OR you stick to topics you actually /do/ know about. thanks.

Uh, all ring sets contribute to compression AND oil control.
As an example, a couple of years ago I inherited an early 1980's Mazda
B2000 P/U with about 160K miles on the odometer that was running lousy
along with oil control problems. The reason, three pistons had broken
compression rings.
In real life, cause and effect can vary widely vs. the published word...

uh, re-read my post. the extent of compression and oil consumpton

Uh, you clearly stated that a compression ring makes little difference
as relates to oil control. In fact, any broken compression ring will
substantially affect oil control.
Additionally, broken oil or 2nd compression rings are rare since the
malady is often caused by incorrect timing (or some other direct factor)
that leads to detonation which is the chief culprit as to ring breakage.

there are 3 rings: top and middle compression, bottom oil control.

out of the 3, the top ring has the least effect!
