In my previous CJ I used to use the Phillips 25/60 Radial Engine Oil and was happy with it. My new plane has been running AeroShell all of it's US life ( 12+ years) and it's a strong, very dry, motor thats working just fine with excellent oil analysis trends.Â
My first thought was to switch to the Phillips at next oil change, but then my 2nd thought was "if it aint broke don't fix it".
I was hoping to get some thoughts on this, since I'm not sure what makes "Radial Engine Oil" any different than flat engine oil.

Here in Europe we can't readily find the Phillips 25/60 Radial Engine Oil, but we use Aeroshell W100 also specially made for radials.
Total D100 in France, but that's the same.
Radial Engine Oil has absolutely no synthetic parts. It is single grade.
It is very important NOT to use any semi-synthetic oil on a radial: the pressures caused by the main piston in the crankshaft (the nr 4 in M14P) are so high that they would crack the synthetic oil molecules, making the oil "less lubricating".
Only my 2 cents,
Jan

Ernie,
I’ve used the 25/60 multi-weight oil for both of my M14’s and I did switch from the 100W that the previous owner used to the 25w60 for the Housai. That said, I wouldn’t switch from 100W unless you really had a reason. One thing with the 100w is that since many of the flat engine airplanes use it, it is easier to find while travelling.
Good luck with the new CJ

Ernie,
You didn't specify if the Aeroshell your airplane has been using was W100, W120 or a multi-grade . I use Aeroshell W120 and found it best for my high temperature environment. Years ago I got smart and tried multi-weight and even worse added Lenkite. The thing leaked out oil like shit out of a Christmas goose. Went back to Aeroshell W120 and haven't looked back.
Even more important would be an engine (unlike yours) that had been run on non-detergent mineral oil. A good way to die would be switching from straight mineral oil to detergent oil (AD). I know somebody that had a total catastrophic failure when he switched to AD oil and the detergent did it's job and loosened up all the "sleeping" gunk and deposits in the engine which plugged the oil system. Over Lake Washington.
It is never a good idea to switch horses midstream (say after 100SMOH or so) when it comes to oil.

I'm currently on Aeroshell W100. But I'm in Florida and wondering if W120 would be better for the hot weather here. But I have to say that this is one of the driest Housai motors I've seen.

Guys,
I've been flying airplanes for over 50 years, and the only shit I really know for certain about is that IF you keep your engine on mineral oil, NEVER mix in a detergent oil. It use to be that mineral oil was used to break-in an engine after overhaul, than you either continued to use mineral oil or you switch to a detergent oil. Times change and you very seldom find mineral oil in stock at FBOs anymore. If you happened to run into a place that didn't have detergent oil - you could add mineral oil to get to you next stop. NOT SO if you used just mineral oil. I've always used a straight grade detergent oil in my M14p (SAE100 winter 120 summer). You can mix the two grades in a pinch. My experience with multi grade oils (beside being expensive) was always the engine suddenly seem to be leaking oil all over the place. I DO NOT KNOW WHY, but except with normal leaks one always finds on radials (mostly push rod tubes and rocker covers) my engine stayed pretty clean most of the time. But one oil change I went to multi grade, and I had oil every where in an engine that was dry before.
When it comes to which oil is better, I'm no expert but what will extend the life of an engine are four things. A good pre-oiler. A good oil filter (20 micros or less). Regular oil changes. And keep 'back loading" to a minimum and reduced max power operation. ( I guess that's 5) The engines on the B-17 and B-24 I get to fly are more sensitive to handling than they are to oil (however the foundation does use multi grade) and because the engines USE oil precociously ( 1 gal/hr ) we don't do oil changes. (besides have you ever tried to dispose of 30 gals at one time?) But we regularly get 1,500 hours on them between overhauls. I believe its mostly because we use pre-oilers religiously and have really fine oil filters. Plus how we operate the engines has a significant effect. I am sure one could make an argument on the advantages/disadvantages of one oil over the other. I personally prefer a straight grade.

Actually, the term detergent oil is an obsolete term, ashless dispersant is more accurate.
Detergent oils were traditionally the heavy truck engine oils containing ashless dispersants AND ash containing detergents.
Because of the negative effect on aircraft engine performance, ash-containing oils must not be used on aircraft piston engines.
The reverse is also true: never use an aircraft piston engine oil in a modern car or heavy duty truck because of the hughe differences in metallurgy, operating conditions and fuel specifications.
The straight mineral oil Aeroshell 100 is absolutely "pure": no additives, straight mineral oil. The Aeroshell W100 has a non ash forming, polymeric additive.
This polymeric additive is to compensate the (early) demand for additives on mineral oil for the high performance aircraft piston engines.
The ancient additives were based on metallic salts of barium (I think). And thus caused ash deposits in the combustion chambers.
But they were needed for additional thermal stability.
A multigrade oil like the Aeroshell W 15W-50 (lycoming etc) is about 50/50 straight mineral oil and synthetic hydrocarbons plus ashless dispersant additives.
They must not be used on radials because the synthetic hydrocarbons can't stand the high pressures in the cranckshaft of a radial.
I personally use Aeroshell W 100 PLUS, that is Aeroshell W100 plus the Lycoming LW 16702 anti-wear additive. This helps when you don't run the engine very often.

Hi Ernie;
I would recommend that you stay with the Aeroshell W oils. Your location does not experience severe temperature changes so W100 winter and W120 summer should be just fine.
With just one exception all of the approved aviation (piston) engine oils are mineral oils. This includes the Phillips X/C 20W50 and 25W60. As far as I know, the only difference (if you can refer to it as such) between radial and opposed engine oils is the recommended viscosity. There is no such thing as an aviation detergent oil (though I believe there was, briefly, some 60 + years ago). There are three basic varieties of aviation mineral oils. 1. No additives (straight) e.g: 100 SUS or 50 SAE. 2. An ashless dispersant additive (AD oils) e.g: W100/ W50. ( the W is used by Aeroshell & Phillips other companies may have different designators)
3. Multi-Grade AD oils with a viscosity modifier added e.g: Phillips X/C 25W60, Aeroshell 15W50. Both use SAE viscosity numbers (60 SAE = 120 SUS).
The exception referred to above is the Aeroshell multi-grade. It is a 50% synthetic. It appears to be a very good oil for relatively modern opposed engines but I would not use it in any radial. Apparently it has been improved over the years but:- I used it in an E225 Continental years ago and found (compared to the previous W100) the oil pressure dropped, oil temp. increased and, over time, it seeped right through the crankcase! About the same time a friend put it in his Harvard (R1340) and shortly after parked it for about 3 months. When he returned there was no oil left.
Personally I have been using 25W60 for some time in CJ’s and Harvard’s primarily due to the seasonal temperature change ( –10C to 40C).

You didn't specify if the Aeroshell your airplane has been using was W100, W120 or a multi-grade . I use Aeroshell W120 and found it best for my high temperature environment. Years ago I got smart and tried multi-weight and even worse added Lenkite. The thing leaked out oil like shit out of a Christmas goose. Went back to Aeroshell W120 and haven't looked back.
Even more important would be an engine (unlike yours) that had been run on non-detergent mineral oil. A good way to die would be switching from straight mineral oil to detergent oil (AD). I know somebody that had a total catastrophic failure when he switched to AD oil and the detergent did it's job and loosened up all the "sleeping" gunk and deposits in the engine which plugged the oil system. Over Lake Washington.
It is never a good idea to switch horses midstream (say after 100SMOH or so) when it comes to oil.

Ernie,
I’ve used the 25/60 multi-weight oil for both of my M14’s and I did switch from the 100W that the previous owner used to the 25w60 for the Housai. That said, I wouldn’t switch from 100W unless you really had a reason. One thing with the 100w is that since many of the flat engine airplanes use it, it is easier to find while travelling.
Good luck with the new CJ

In my previous CJ I used to use the Phillips 25/60 Radial Engine Oil and was happy with it. My new plane has been running AeroShell all of it's US life ( 12+ years) and it's a strong, very dry, motor thats working just fine with excellent oil analysis trends.
My first thought was to switch to the Phillips at next oil change, but then my 2nd thought was "if it aint broke don't fix it".
I was hoping to get some thoughts on this, since I'm not sure what makes "Radial Engine Oil" any different than flat engine oil.

Thanks Pappy, Walt, Jan,
I do remember having a lot more oil pour out of my exhaust during prop pull
thru, with the X/C.
W120 it is then.
Should I use MMO? Just kidding,  No really, I'm just kidding.

3. Multi-Grade AD oils with a viscosity modifier added e.g: Phillips X/C 25W60, Aeroshell 15W50. Both use SAE viscosity numbers (60 SAE = 120 SUS).
The exception referred to above is the Aeroshell multi-grade. It is a 50% synthetic. It appears to be a very good oil for relatively modern opposed engines but I would not use it in any radial. Apparently it has been improved over the years but:- I used it in an E225 Continental years ago and found (compared to the previous W100) the oil pressure dropped, oil temp. increased and, over time, it seeped right through the crankcase! About the same time a friend put it in his Harvard (R1340) and shortly after parked it for about 3 months. When he returned there was no oil left.
Personally I have been using 25W60 for some time in CJ’s and Harvard’s primarily due to the seasonal temperature change ( –10C to 40C).

I'm currently on Aeroshell W100. But I'm in Florida and wondering if W120 would be better for the hot weather here. But I have to say that this is one of the driest Housai motors I've seen.

You didn't specify if the Aeroshell your airplane has been using was W100, W120 or a multi-grade . I use Aeroshell W120 and found it best for my high temperature environment. Years ago I got smart and tried multi-weight and even worse added Lenkite. The thing leaked out oil like shit out of a Christmas goose. Went back to Aeroshell W120 and haven't looked back.
Even more important would be an engine (unlike yours) that had been run on non-detergent mineral oil. A good way to die would be switching from straight mineral oil to detergent oil (AD). I know somebody that had a total catastrophic failure when he switched to AD oil and the detergent did it's job and loosened up all the "sleeping" gunk and deposits in the engine which plugged the oil system. Over Lake Washington.
It is never a good idea to switch horses midstream (say after 100SMOH or so) when it comes to oil.

Ernie,
I’ve used the 25/60 multi-weight oil for both of my M14’s and I did switch from the 100W that the previous owner used to the 25w60 for the Housai. That said, I wouldn’t switch from 100W unless you really had a reason. One thing with the 100w is that since many of the flat engine airplanes use it, it is easier to find while travelling.
Good luck with the new CJ

In my previous CJ I used to use the Phillips 25/60 Radial Engine Oil and was happy with it. My new plane has been running AeroShell all of it's US life ( 12+ years) and it's a strong, very dry, motor thats working just fine with excellent oil analysis trends.
My first thought was to switch to the Phillips at next oil change, but then my 2nd thought was "if it aint broke don't fix it".
I was hoping to get some thoughts on this, since I'm not sure what makes "Radial Engine Oil" any different than flat engine oil.

"driest housai I've ever seen"
Just means it hasn't got any oil in it
