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.

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).

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.

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.

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.
