If you ever go to Mexico don't forget to fuel up your diesel engine, border diesel from Mexico is imported from the U.S. you'll pay around $2 USD! per/Gal

Looks like unreacted oil.

but it passed the 3/27, could that be unreacted oil? remember this is the water/BD shake test, not a 3/27...

They look like oil, but there are only two ways I can think of that oil droplets would be at the bottom of the water layer:
1) they're stuck to the glass, or
2) they're silicon oil, which is denser than water, and won't react with methanol or lye (or much of anything else).

I don't know if silicon oil (like DOT-5 brake fluid) would form droplets, or would spread out into a film.

They're not soap or glycerin - those are water soluble.

Unreacted oil would float on top of the water layer.

The water looks nice and clear, so your reaction must have been pretty complete, or your washing process was thorough.
