Sorry Frank still not buying that. The seal only works one way? Really?
Nah. Where is all this grease coming from? I don't plaster CV grease round the seal so somehow it had to jump across a gap and through a seal.
Nah
This seal is only tight one way?
Nah? Have you slipped one on a shaft to see how tight they are?
Nah.
I think this is cheap oil that us being broken down mechanically. I'm not missing grease from my hubs either.
Nah

Oil seals are either single or twin lipped. Single lip is for internal use such as the one we are discussing and yes, it is one way. If you need to exclude external matter, such as dust or water, then you fit a twin lipped seal. If you look at a TW seal, you will note that the lips are different in design as they do different jobs. The outer seal will stop water in the form of rain or a water crossing or even a garden hose but not a pressure hose.
The grease is coming from the rotation of the CV joint as it spins in the hub. The vortex of air will spray it all over the place.
It would be very difficult to claim "no loss of grease" as from experience it just goes gloop into the drain tin when you remove the outer seals to the hub.
I still reckon it's grease.
Anyway, what were you doing buying cheap oil? I'm thinking of reporting you to the Toyota police for cruelty to LC's.
