It is not unusual, and is generally the rule, that your Lycoming 540 wil

is the inverted system and what you sacrifice in oil during transition
from right side up to right side down...!
Each engine/airframe combination on every piston engine aircraft I have

encountered has a certain oil level happiness somewhere under the total
capacity
of the engine. It is generally understood that it there is no real phys

Thanks for your post. You seem to discrbe my engine well. To clarify

currently have the over flow dropping on the exhaust pipe to get burned

I have calibrated my dipstick as each two quarts were added so I feel

Jim,
How long does it take your engine to get down to 8.5qts from full, and
once you "R" there how fast/slow does it go down any further to 7qts,
6qts, etc.? I will "hold" 12qts if never used, but will "keep"
certainly less then that when in operation. I would monitor the engine's
oil usage (burn & waste) and note when it stops to puke oil on the
belly. Then run it there (but do pay attention to the oil level). I
read somewhere that the high oil capacity was a requirement for
endurance runs during certification, but the engine does not necessarily
be full to the gills for daily operations...

If done properly, it can also enhance breathing by generating a partial

Note that in Type Certificate Data sheet E-295 for your Lycoming Engine
that there
is a minumum safe oil quantity listed for different angles of pitch as f
ollows:
20 degrees nose up or down = 2.75 Quarts
30 degrees nose up = 4.0 Quarts
Maybe this will give you some perspective and comfort when running 8.5
quarts.

Since then, it seems that anything over 8.5 qts or so, I loose it. I

Jim,
If it makes you feel any better, the 4-cylinders call for full at 8qts,
but realistically anything over 6 - 7qts gets dumped overboard as
well...
Oilchanges do get a bit cheaper if you don't fill it with a full 12qts
and use just 9qts instead and therefore not waste 3qts on the belly.

7qts, 6qts, etc.? I will "hold" 12qts if never used, but will "keep"
certainly less then that when in operation. I would monitor the engine's
oil usage (burn & waste) and note when it stops to puke oil on the
belly. Then run it there (but do pay attention to the oil level). I
read somewhere that the high oil capacity was a requirement for
endurance runs during certification, but the engine does not necessarily
be full to the gills for daily operations...

Vacuum pumps are almost always used to generate negative crankcase
pressure in high performance engines. Oil suction is controlled through
system design.
In many cases, the crankshaft oil seals are installed backwards.
(depending on the amount of vac)
No elaboration needed here. If you are not familiar with purpose, this
will not become a
dissertation on the why and how. Just thought to enlighten the
unfamiliar.
No further commentary from here

Be careful thinking that a partial vacuum is desirable in the breather
tube. This can create more of a scavanging effect than is
necessary...all the engine really needs is a "vent".

If done properly, it can also enhance breathing by generating a

It is not unusual, and is generally the rule, that your Lycoming

I have ever encountered has a certain oil level happiness somewhere

It is not dangerous at all to run your 540 @ 8.5 quarts. The
only reason I would put any more oil in your sump would be if you are
planning on doing some aerobatics, or going on a longer trip, (I would
guess that your airplane doesn't have those kind of legs anyway).
Another thing I might mention is it would be a good idea to

I think that the 0-540 is trying to tell you that all it will keep in
the sump/engine at one time is 8.5qts. No matter what the op manual
says, that's all your engine wants and if that is not BELOW minimum
operational capacity-it's OK. EVERY engine has it's peculiar aspects.

| Subject: | Re: Oil capacity |
It seems that this is always an interesting topic - or at least a
topic of interest...
I've heard a number of explanations for the apparent increased oil
consumption when full. One that seems to make sense is that when the
oil level is up to the gears in the accessory case the gears tend to
"pump" the oil to the top. At the very top is the camshaft gear
which then deposits the oil into the blowby stream. The engine will
burn a lot more oil during takeoff than any other part of flight (low
speed and high thrust). I don't know if I buy that, but that's the
story. One thing that most engines are sensitive to is rpm - at high
rpm more blowby is generated and therefore more oil is dumped
overboard. At high rpm the piston rings can start to lose control of
oil on the cylinders and the engine will burn more oil. I had a "L"
engine that would burn a quart every 6 at 2400 but I could go at
least 10 at 2200 rpm. As far as oil capacity, note that most 540's
have 12-quart sumps, but the L has an 8-quart sump in order to make
room for the nose gear on the R182. Why could Lycoming "arbitrarily"
reduce the capacity to 8? Maybe there was some logic as the max rpm
for that engine was 2400 (lycoming builds other 2400-rpm engines with
12-quart sumps, though. The real high value for oil level comes from
the oil consumption, aircraft endurance and convenience. I fill my
540 to 10 and never let it go below 8. If I am at the home hangar I
will put a quart in at 9, but if I am on my way home I will only put
a quart in at 8. Mine burns about a quart in 6 hours and my
endurance is 6 hours, so I only need to have 1 more quart than the
minimum to make the trip. However, consider this: If something
happens (did happen to me once) that increases the oil burn
dramatically, you will be very happy to have put in some extra oil.
I had a 4-cylinder and broke a ring, burned about 3 quarts in less
than an hour and landed with 4 quarts in the sump.
The 550 Continentals seem to come with either 8 or 12. I think the
turbo engines get 12 and the naturally-aspirated engines get 8.
Regarding pressure (or vacuum) in the crankcase - it doesn't matter
much as the engine doesn't care - except... Very high rpm engines
will consume a lot of power pumping blowby around the crankcase and
reducing the pressure of those gasses will reduce the power consumed
as Archie implied. And take the case of the 2-cylinder BMW opposed
engines. Some or all (mine, at least) have a check valve in the vent
that lets air out but not in. Both pistons come in together,
creating a very high flow in and out the breather. By using a check
valve the pressure in the crankcase is reduced and only the "fresh"
blowby is pumped out the check valve. The average pressure in the
crankcase is much lower than atmospheric. Regardless, the actual
quantity of blowby will stay about the same.

Subject: Re: LycomingEngines-List: Oil capacity
Jim,
How long does it take your engine to get down to 8.5qts from full, and
once you "R" there how fast/slow does it go down any further to 7qts,
6qts, etc.? I will "hold" 12qts if never used, but will "keep"
certainly less then that when in operation. I would monitor the
engine's
oil usage (burn & waste) and note when it stops to puke oil on the
belly. Then run it there (but do pay attention to the oil level). I
read somewhere that the high oil capacity was a requirement for
endurance runs during certification, but the engine does not
necessarily
be full to the gills for daily operations...

Without revealing too much regarding our racing engines, one
consideration
would be to plumb the breather into your exhaust collector.
If done properly, it can also enhance breathing by generating a
partial
vacuum.

Thanks for your post. You seem to discrbe my engine well. To
clarify
one issue. It does not seem to matter if I do acro or fly straight
and
level cruise, that oil gets pumped out and ends up on the tail. I
currently have the over flow dropping on the exhaust pipe to get
burned

I have calibrated my dipstick as each two quarts were added so I feel

It is not unusual, and is generally the rule, that your Lycoming
540
will not keep down the full 12 quart capacity in the sump. Adding to
your particular situation is the inverted system and what you
sacrifice
in oil during transition from right side up to right side down...!
Each engine/airframe combination on every piston engine aircraft I
have ever encountered has a certain oil level happiness somewhere
under
the total capacity of the engine. It is generally understood that it
there is no real physical explanation for this except it is agreed it
has to do with the design of the breather system of the engine in
combination with the breather systems that are part of the airframes
they are installed on.
It is not dangerous at all to run your 540 @ 8.5 quarts. The only
reason I would put any more oil in your sump would be if you are
planning on doing some aerobatics, or going on a longer trip, (I would
guess that your airplane doesn't have those kind of legs anyway).
Another thing I might mention is it would be a good idea to check
the accuracy of the dipstick. This is best accomplished during the
next
oil change by adding oil a quart at a time....well I would guess you
understand this concept... !

Note that in Type Certificate Data sheet E-295 for your Lycoming
Engine that there
is a minumum safe oil quantity listed for different angles of pitch as
follows:
20 degrees nose up or down = 2.75 Quarts
30 degrees nose up = 4.0 Quarts
Maybe this will give you some perspective and comfort when running
8.5 quarts.
Just plan your flying sessions considering duration and environment
based on
this information and enjoy a cleaner belly...!

I just finished the 40 hour test period and the engine is broken in as

12
quarts, after shutdown, I had 8. The rest of it was apparently dumped
as my rudder was covered in clean oil.
Since then, it seems that anything over 8.5 qts or so, I loose it. I

Jim,
If it makes you feel any better, the 4-cylinders call for full at
8qts,
but realistically anything over 6 - 7qts gets dumped overboard as
well...
Oilchanges do get a bit cheaper if you don't fill it with a full 12qts
and use just 9qts instead and therefore not waste 3qts on the belly.

Vacuum pumps are almost always used to generate negative crankcase
pressure in high performance engines. Oil suction is controlled
through
system design.
In many cases, the crankshaft oil seals are installed backwards.
(depending on the amount of vac)
No elaboration needed here. If you are not familiar with purpose, this
will not become a
dissertation on the why and how. Just thought to enlighten the
unfamiliar.
