I agree with Dennis about Aero shell 15W50. It can coke up your air
compressor in record time. 25W60 seems to be Ok and we use it a lot in M14P
engines.

I have been advised not to use the 15W50 oil in these engines. But I would
confirm that with the engine experts like Monte Barrett and Carl Hays. If
you want to use a multi-viscosity oil, go to the Philips 25W-60 which is
designed for radial engines.
For the sake of discussion, lets assume there was no Philips 25W-60 (mineral
based) oil on the market and your only choice after break-in is to drain the
break in mineral oil and replace it with a W100 or 120 oil. What would you
do? I see no reason whatsoever that you can not switch to w100 or 120.
Again, if your that concerned about it, please ask Monte Barrett and/or Carl
Hays.
Remember, this information is only worth what you've paid for it. :-)

<didier.blouzard@gmail.com>
OK so as far as I read I can see nice pics and nice cars but no answer...
is it possible to change from mineral to 100W without danger (obstruction
of oil system due to mud going into the system..).
If I understnd well Deniss it could be possible to use a mineral based oil
better than the aeroshell. But changing to a W100 (for example??)
Is it possible to use a 15W50 for example??
Kind regards

Not to throw a quirk in this but what if I don't have a compressor to coke
up.
I would prefer to use Aero Shell !5W50 because of the temp. we have here in
Utah.
Does this affect the warranty that you have on your engines.

I certainly do not question your experience, George and Dennis. But it seems
that your opinion about 15W50 is mainly based on someone else's experiences.
Very understandable and acceptable, because we can't afford to test it all.
But why is the W15W50 not good? If you look at the specifications, it has a
much higher viscosity index than the W100.
It is slightly less dense (0.86 kg/l instead of 0.89 for W100 or W80) but
the kinematic viscosity is higher than W80 and slightly lower than W100.
It has less carbon residue than W100, less sulphur, less ash, less acidity.
Has it been tested on Russian radials? Probably not. The Russian Design
Bureau does not accept it, but they don't know it. It is accepted for all
the Pratt and Whitney radials.
So, if you look at the specifications, it should be very good. Of course,
there are not many M14P engines left to test it thoroughly, and I will
certainly not test it on mine, I am perfectly satisfied with the W100.
Can you explain why it would damage the air compressor?
The reason why I am interested, is the very humid climate we have in
West-Europe. Our engines should run regularly to boil the water out of the
oil, so that the water can't react with the combustion byproducts of the
tetra-ethyl lead in AVGAS 100LL: 0,56 g/l, MUCH more than what we used to
have in the former mogas with lead; perhaps one other good reason to use
MOGAS.
This reaction is acidic, and a cause for corrosion. Maybe the W100Plus is
the best answer to that. But the W100Plus is not officially accepted either.
In Europe, we don't have the liberty to use whatever we want ...

It is my understanding that there is an additive in the 15W50 that will
glaze over the rings in the air compressor. This is particularly true at
higher temperatures. (especially if the cooling blast tube is not properly
maintained) Aeroshell may have changed their formulation in the last decade.
Our experience in the middle 1990's particularly in engines that were
running on Russian oils was to steer clear of 15W50. It is only our
opinion. If you want a multi grade use the Phillips Radial engine oils. they
not only work well in our experience they are lower cost.

Anyway, the Aeroshell W100Plus has the same additives as W15W50. In the
UK, several Yak owners use W100Plus.
As I already stated, I do not doubt George, Dennis or you.

Hi:
I usually stay out of these but, the time I have used a multivis, other
than the Phillips, it literally ran out of the engine when we shut them
down. We were standing around watching this in Louisiana on a hot day.
This has happened twice and we changed the oil back both times to
straight weight.
The Phillips has worked great for us in several engines with several
hundred hours in service. I used it for flying airshows for 10 years
without a hitch. And that is pretty sever usage as the plane is landed
hot in the summer in the South and usually did not have much drain
through of either the straight AeroShell 120 or the Phillips multivis.
In closing I would have to say for anyone who doubts George, Dennis, or
