As Doc Kemp suggested, it is really wise to just replace the thing with a modern antenna design. I personally pulled mine and replaced it a long time ago. Yes, it is a little bit of a pain in the tail to make a metal plate to fit the location where the original antenna goes and drill it to also accept a new antenna design, but it is worth the time to do so. Comant (sp?) sells several very good model antennas... one that even includes a GPS antenna inside. Cool. Not cheap, but last a LONG time.

The only aviation semi-synthetic that I know of is Aeroshell 15W50. The Precision Engines letter was excellent in that it explained in detail the reason for the caution notes in the P&W SB. I totally agree that 15W50 and 20W50 should not be used in radial engines (and I would include the smaller ones). 25W60 on the other hand is probably OK for the small radials. It is nominally equivalent to 120 at higher temperatures (60 SAE = 120 SUS) though this is probably degraded by the ashless dispersant and viscosity modifier additives. Maybe the end result puts it closer to 100 SUS ? Don't know for sure but the P&W SB does recommend the use of a higher number with additives. The only disappointment in the Precision letter was no reference to the performance of 25W60.

It has long been known that the flat engine multi-grade oil has some additive for anti-corrosion (makes it cling to cam followers and the like for longer periods of disuse) that gums up certain things in M-14P engines (I think the compressor pop-off valve has been mentioned). Certainly, you don't want to use these oils, and that's probably what Precision is cautioning against. This does not apply to the Phillips 25-60 oil that was designed specifically for radial engines. It is mineral-based (not an AD oil) and can be used for break-in. It doesn't have the anti-corrosion additive that causes trouble. Aeroshell W80, W100, and W120 (these are AD-type with the red label) also seem to be fine. In Aeroshell, the straight mineral oil (80, 100, 120 with the blue label ) has to be used for break-in. The radial engine shops I know all like the 25-60 (Radial engines OKC, Tulsa, M-14P, Inc., etc). I have noticed that some people with smaller Pratts (like the R-1340) use mineral all of the time, especially if they're nursing an old engine. Certainly, the Phillips 25-60 is very popular (the most common for old radials that I've seen). Some hard-core Russians seem to like to stick with the Aeroshell. Not that they had that stuff in Russia back in the day. I have heard that the main issue with them is that the flop tube in the oil tank has a seal that is formed by a coating of oil, and the 25-60 doesn't maintain that seal when the flop tube joint becomes worn. This only becomes a problem when flying torturous up-lines in unlimited akro (Sukhoi), and in high ambient temps, where oil pressure can drop off. Even this is debatable, and it certainly doesn't apply to 99% of us. My disappointment with the Precision letter was their unfamiliarity with adverbs when choosing a slogan.
