Ask them how to clean the well/stacked ball bearings and what type/quantity of oil to use.
You will need to clean the well, and clean/inspect the ball bearings anyway (might as well do it right the first time).
Regardless of what I've read online I would never use automotive oil in a TT bearing and as mentioned 3 in 1 is not suitable (I avoid multi-purpose oil in general).
