Is anyone running Amsoil 10-40 full synthetic. I have heard some pilots
run this in light singles. I realize it is not certified , so they must
think full synthetic is better than dino oil .

I hadn't heard that, Kevin. That Amsoil sounds interesting. Do you know
anyone I could buy some from?

I buy mine from their website. I changed my cars to full synthetic after
my friend
who's son is a chrew chief in the AF said they ran only synthetic oil
in the AF turbines. If synthetic can stand up to the high operating
temps of turbines, with the rpm's they turn, and not break down or boil
it would have to protect a recip engine better than dino oil. That
should translate into a large increase in engine life. If it will
protect the engine better i dont care if is FAA certified or not. They
are not the one depending on the engine , I am.

I don't know much about oil, synthetic or otherwise, but just for my
information wouldn't running uncertified oil in an airplane be
considered a fairly serious violation by the FAA? I'm not trying to
argue about it, since I don't care one way or the other about what
people put in their planes, but I am curious. If you had an
engine-related accident and were running uncertified oil, would the FAA
hang you out to dry? Would your insurance company use it as an excuse
not to pay up?

Bad analagy.

The requirement for turbine oil is completely different than for piston
engine oil. Turbines are all ball bearing and don't have parts sliding
against others. The loads in turbines are much lower than in piston
engines. For instance the torque developed in the core of my 1000hp TPE-331
engines in only 131 lb. ft. whereas a 300hp IO 540 developes about 600lb ft.
The critical components in a piston engine from a lubrication standpoint are
the cam and lifters which can have loads of over 100,000psi at the interface
between them.

All this means that piston engines require a different oil than turbines.
If you had put turbine engine oil in your piston engine, it would be junk
now.

Turbines don't have the sludge buildup issues that recips do.
Burning kerosene vs leaded gas, etc.
That's why Mobil One lost the FAA blessing.
The pure synthetic oil is so slick it can't hold lead in suspension.
In my TSIO520WB's I use straight 50 weight Aeroshell.
I change it often.

That's exactly correct. There's nothing wrong with the oil; the
problem is that we're still using lead in our fuel, and lots of it.
The full synthetics won't hold the lead in suspension. I know people
who are running the lower compression aviation engines on autogas and
Mobil One. The longevity of the engines, and especially their ability
to resist corrosion when they sit, is nothing short of incredble.

Maybe you better think about the operating differences of our
company's turbines and our own light planes with the small recips. If
Mobil couldn't do it, what makes you think that an individual come up
with the method. Don't screw around with airplane engine oil. Our
cars are a completely other thing.

Hard to imagine a more apples and oranges argument.

Not meant to be an argument , just a question. I have been set straight
, and understand synthetic is not an option for recip engines.

Thanks to all for the help

Actually synthetic is fine for recip engines if the additive package is
appropriate.

At least in cars, a big plus for M1 was the viscosity when it was
cold old. As in, -30C, which was the case in MinneySota. You really
noticed the lower cranking effort vice normal 5-20, etc.

My Victor Blacks are not in a car, they're in an injured but hopefully
curable P Baron.
The folks from Beech in San Antonio have been up to San Marcos twice.

My Carrera 4 uses Mobil One.
Every 15,000 miles.

My Baron can make Belize in 4 hours from Austin.
My Porsche can't.

Apples and Oranges are both fruit.
This analogy needs more differential.


Don't think you are smarter than a century of bloody experience just because
the FAA won't sign off on a can of oil.
