Sorry, my lawn roller is just a tank and does't have a head or a tail.

The gease was noticed on a mixture of virgin antifreeze that was obtained
from the few drops that was left in each container.   The grease might have
been auto-transmission fluid since I did use a funnel that had been used
for AT fluid several months before and had only been wiped out with a paper
towel.  Still the mix looks very non uniform compared to the nice translucent
appearance of the original mixes.
