Maybe I'm confused, but I thought oil and silicone were entirely different
classes of materials. The WD40 and silicone lubricant I have handy
aren't similar -- the silicone is clear while the WD40 is yellowish,
and the silicone has a distinctive gluelike smell. Also, the silicone
can explicitly says it's ok for rubber.
Now, the silicone does carry the warnings about open flame, so I guess
you could use it to find leaks -- but it would clog your OXS. Best to
use a gas in any case.
