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.

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??

Hey Tiger,
Two things. First, why did you let your wife beat you with the 9 iron?
Second, quit asking so many annoying questions about oil. Do you think the experts are going to tell you what to do? Be a man, put whatever you want in the damn thing. Just quit whining.
Put 100w or 120w or 5/95, who cares the engines run fine and leak with anything you put in them.
Hey, try KY or pure seasoning Olive Oil.......

Hey Dider, I'm right there with you man,
I'm switching from 100w to 25w60 for Radial engines and was scared of the whole thing.
Better ask while you are on the ground.

The aeroshell W100 IS a mineral oil, 100%.
Aeroshell 100 is monograde, without anything at all, for brake in, the
Aeroshell W100 is the same monograde 100% mineral oil with an ashless
dispersant lubricant. You can change to Aeroshell W100 at any moment. Once
you changed, there's no need to go back to the straight 100.
The Aeroshell W15W50 is a SEMI-SYNTHETIC oil, and should be very good, but
the Design Bureau in Moskou did not accept it YET. Tests are going on.
Although the W15W50 is accepted for all radial P&W's.
You could also use the aeroshell W100Plus, that has some extra additives
against corrosion. (Good solution for engines that don't run very often).
All these oils are within the SAE 50 specifications.

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.

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 ...

Jan

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.

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 myself should just go try it and let us know how it works for you. I always like hearing from test pilots about their experiences.<grin>

Subject: RE: Re: Changing type of oil
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 ...

Jan

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.

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 myself should just go try it and let us know how it works for you. I always like hearing from test pilots about their experiences.<grin>

Good to hear you are still out there!!!!
I would not really have any experience about oil, and M-14 Radials..... I own one, but do not actually have one....

Hi Dave:
Your engine has been ready to ship for a long time I was waiting on the payment for the cowl. I can ship Monday if you want to wait on the cowl. I still have the instructions for shipping.
Thank you,

Hi George
I purchased the MP 14 engine from you last year and it , is almost ready to start, I have drained the preservative oil out, and would like to know what oil you recommend after draining that .

apparently the Philips is the best from our last discussion here. But Aeroshell W100 is really fine. I personnaly add some additive which is Bardhal. It seem that the motor looks much better and can last much longer.
But This is what I know. I let the pro of the list give their best answer.
Kind regards

Typically they were run for 3 to 4 hours during the run in and testing. We
use mineral oil for the first 30 hours. Our practice is to make an initial
oil change at 5 to 7 hours and the next change at the 30 hour mark. We also
check and re-adjust the valves the 30 hour mark and then at every 100 hrs or
annually.
