David::
Diesel engines are high compression, and subject to temperature conditions
that do not apply to aircraft engines. The best oils for these low
compression, slow turning engines are the Aeroshell 100, 50 weight, single
viscosity Ashless dispersant oils. Normally Mineral oil is used during the
"break-in" period of these engines. Some people use the Multi viscosity
aircraft engine oils for climates with extreme low winter temperature
conditions. I still used the Aeroshell 100, 50 wt oil when I was flying in
extreme cold in Alaska. I would not mix oils in an aircraft engine.

Speaking of which....
I just bought a case of 15W40, hoping to use it in my Coupe. (It is
generally used as diesel engine lubricant.) Any experts out there re
oil options? Should this be OK in winter? Summer?

That would be .85 Lbs at 85 HP in one hour or about a quart every three
tanks of fuel. Sound right? 85 X .01=.85,

According to a conversation I had with an apparently knowledgeable
fellow
at Continental Motors, the oil consumption limit is .01 lbs. / brake
HP /
hour
I neglected to ask if he meant the assumed power output at the time or
the
nominal engine HP - at the time the assumption seemed nominal engine
HP
If I did the math right, if you take less than 27.5675 minutes to suck
a
quart, that's too much, based on 85 HP and 7 1/2 lbs. per gallon - I'd
be
interested in correction if I mathed rong

(my engine takes a little longer, but it runs really well and has low
hours (operating), but high hours (calendar) - as far as the calendar
hours go, the Continental guy told me that their concern is for things
such as rubber seals and the like that are apt to degrade with time -
so I
feed its habit)
