Well, speaking from experience, not logic...
I can get 10 tach hours on 6 quarts if I take it easy, less than 75% power. But
if I make a single 1 hour flight, 2700 RPM, down low, it'll shoot out a half
quart down to 5.5 in that one flight. And that's measuring before the next flight
after the oil has had a chance to drain back down. I've repeated this experiment
multiple times.

| Subject: | Oil Temperature Control |
I hate to change the subject about oil level but I recently made and
installed a valve that will control the air flow to the inlet of the oil
cooler on my O-320 powered Lynx. When I installed this engine several
years ago I wondered if the small stock AA-1C cooler would be adequate
but decided to use it until testing proved otherwise. It has worked
well even at high ambient temperatures during extended climbs. But my
cooling with this engine is actually better than needed and during the
cool weather here in the NW the oil temperature will not get up even
close to 175F where there is half a chance of evaporating the moisture.
I got tired of taping over the inlet to block part of the air flow so I
fabricated a cockpit adjustable air valve to regulate the flow and
therefore the oil temperature. It's operated by a simple push-pull
cable with a ratchet lock, much like th stock mixture cable. A test
flight a couple of days ago showed a 20F temperature reduction from no
air flow through the cooler to maximum flow with a 2" diameter supply
duct. This was at about 80% power at 3000 msl and 40F OAT. Pretty good
for such a small cooler. But the real benefit is the ability to
regulate the oil temperature for operation in a more ideal range.
Larger coolers which are commonly used probably result in more like 30F
reduction.
Also, there was some discussion recently about how to route a manifold
pressure line. I did it very simply with a connector from the #3
cylinder and hose through a snap in bushing in the rear baffle to a
bulkhead fitting on the firewall. This may not work as well with the
normal baffling.

If you run the engine hard, the pressures inside the engine are higher and
it pushes more oil out the breather. -It will still settle down at somewh
ere between 5 1/2 qts and 6 1/2 qts.=0A=0AThe engine in my plane likes abou
t 5 1/2 to 6 qts. -I usually add at 5 1/2 qts. -=0A=0A=0A______________

I was wondering about that. -The internet says OK averages 50 earthquakes

| Subject: | Which plugs for our planes these days |
I see listed these days a Fine Wire option and a Massive Electrode option, this
my be old but new to me, I went out to fly this evening and had a plug fouled
and would not clear so was going to order a set to have available to rotate in
when I am in a pinch and need to make a quick swap if this happens again. What
it the best choice these days.

Hi Doug,=0A=0AFine wire plugs work great . . . with one exception: -Fine
wire plugs are expensive. -=0A=0AGenerally, the massive electrode plugs w
ork just fine. -Clean and gap about every 50 hours. -Lean aggressively.
=0A=0AI would recommend that you install the REM-37BY plugs. -They are ex
tended electrode plugs similar to automotive plugs. -These have less of a
tendency to foul. -They self-clean by exposing the electrode to the swir
ling gases in the combustion chamber. -Non-extended electrodes bury the e
lectrode deep in the plug. -These will foul more easily. -=0A=0AGary=0A

I have an extra box of the Champion fine wire iridium plugs. I'd take $50 each
for the box
