A message I cut and pasted from a different list.
Anyone have any comments on using say Castrol 20W-50 in a Lycoming clone
using auto fuel?

At engine tech sessions at Sun-N-Fun this year, a Shell oil engineer
advised that a minimum temp of 185 F was necessary to 'cook' out the
moisture that collects in the engine innards due to condensation. Less
than that and you decrease the life of the engine, and the effectiveness
and life of the oil because the water is never evaporated.
He also stated that sustained temps over 220 F should be avoided,
because of the reasons Chuck shared below, as well as varnish formation,
carbonization, and other heat related baddies.
Another bit of information he passed on was that the formulation of
aviation oils and the use of auto gas was a problem area. The additives
in aviation oil are not necessarily compatible with the additives in car
gas and that the by-products created by burning the car gas would break
down the aviation oil before the recommended 25 hour oil change
intervals. He didn't go so far as to recommend using auto oils in
airplane engines burning auto gas (did I mention he worked for
AeroShell?!), but I doubt there is much risk in doing that considering
the high performance, high heat, high rpm engines in cars these days -
the oil they use is likely durable enough to withstand aircraft engine
stresses (primarily talking about Lyc's and Conty's - not necessarily
auto engine conversions).
Anyone out there running an A-65, 0-200 or 0-235 on auto gas? What oil
are you using and do you have anything to share?

Hi, I have been using 87 octane auto fuel and aero shell 15-50 for 12
years. no problems found. change oil at 20 to 25 hours depending on
utization during the year.

I Should have been more specific I was thinking more about the IO360 I'm
looking at.
Thanks

I built several "custom" high hp O-200's, and insisted they do not use
mineral oil for break in, due to the parts and machining methods
incorporated.
One engine was run-in on my dyno, and needed no further time.
On the subject of water formation due to condensation, there is no breather
system as most would be familiar with.
I incorporated exhaust augmented vacuum (with a check valve) in the
crankcase which causes negative pressure when the engine is running.
When the engine is shut down, there is little to no atmospheric venting
which reduces condensation formation.
This may not work well with conventional aircraft rings and wall preps
that require a long break in period, as they do not seal well enough to
take advantage.
BTW, The oil stays clean for over 20 hours, and starts darkening around
23-27hrs.
One of the engines also has an accusump oil pressure accumulator which
insures oil pressure at all times, and allows the pilot to pressurize the
oil
system prior to engine startup.
Nuff said,

Maybe not directly applicable but I use 94 octane auto fuel (compression
ratio 9.6:1) and 15-50 oil in summer and 5-40 in winter. My engine is a
modified Rotorway RW-100 (EFI) but only has about 50 hours on it. Oil has
been changed twice.
