Re: lower grease?
My advice would be to change it out yourself, so you know exactly what you put in. This way you can monitor the oil quality yourself by comparing the oil in the case with leftover oil in the new bottle. When I think about avocados, I think opaque green. Depending on the lube used, it should be somewhat translucent...like honey...not like paint!
Changing the LU oil is something that is very easily done and should be done at least once a year while replacing the plug washers EACH time you remove the drain/fill plugs.
