I've always been curious about one thing with these long transoceanic single
engine flights: how do you handle the oil consumption? It seems like most of
the planes I've flown over the years would have burned up much the oil in the
sump over 19 hours.

There are mechanisms that allow you to add oil to the engine while
in flight.

I don't fly them airplanes!!!! A healthy engine will burn about 1/2 to 1qt
every 10 to 15 hour. Pluss our powersettings are very low 55 to 60%

The plane I flew that burned the most oil was a 1955 TriPacer. At the
time, the engine had about 2200 hours (200 past TBO) and 42 years (30
years past TBO) since new - never overhaled! It had served as a cargo
hauler, had sat for years without flying, had racked up many of its
hours back when lubricants were nowhere near as good as they are now -
and it burned 1 qt every 4 hours. Sump capacity was 8 qt, and minimum
for safe flight was 2 qt. At that rate, it would need 24 hours to get
unsafe. That was at high power settings - at low power settings it
burned less.

I have no idea where you would find a plane that would use more oil
that someone would buy and pay to have flown transoceanic - and who
you would find to do a transoceanic ferry in it even if someone was
going to pay for it.

Personally, I would think twice about flying such a plane at all - and
certainly would only fly it day-VFR over relatively good terrain for a
forced landing.

I always do a 4 to 5 hour oil burn test flight on anything I take over the
pond.

I should have known you'd be picky. G

Most of my flying career involved flying crap.

Where did you get those numbers? Lycoming says maximum allowable oil
consumption is almost .6 qts/hr:

The maximum allowable oil consumption limits for all Textron Lycoming aircraft
engines
can be determined by using the following formula:

..006 x BHP x 4/7.4 = Qt./Hr.

The O-360 in the 172RG I owned burned a quart every 7.5 hours from the day it
was broken in until the day I sold it seven years later. Some burn more, some
less, but a quart every 20-30 hours is quite low.
