Here is a company that makes an oil level sensor that can be used both
on Lycoming engines and Mazda Rotary engines (with a little adaptation
of the oil pan).  It can trigger a signal much sooner than the sensor
that is built into the 13B engine.=20

I think it is useful to know if you are losing oil before it is all
gone.  Even a few minutes of warning could make the difference between a
safe landing and an engine out landing (or crash) in an undesirable
location.  Oil leaks can occur for a number of reasons, including broken
hoses, loose fittings, ruptured oil coolers, etc.  I am using the oil
level sensor that came with the 13B engine.

True enough. But if it's reliable and sufficiently generic, it might=20
serve Lycoming owners (of which, sadly, I am one) well. As you are=20
probably aware, one of the more interesting features of Lycs is the=20
front seal, which has a nasty habit of "falling out" at irregular=20
intervals for reasons best known to itself (most recent example: just a=20
few hours TTSN). Major thread around that on the Cozy list as we speak.=20
The problem is aggravated with pushers since we have no way to detect=20
the failure until the oil pressure goes to zero, and that's pretty late=20
in the game.

What's it look like? How does it work? How is it installed? ... Jim S.
