|As for lube, there are two types of lube I use, "Real Lube" Bass Pro or "Corrosion Block" from West Marine. It's the main grease I use for the gears.
I use a light weight oil for my bearings. I use to use Quantum "Hot Sauce" but the red oil stains everything. I now use "Corrosion-X" for the parts that need oil rather than grease.
I use either Shimano or Cal-Star bearing grease on my drag disks (carbon, ceramics and others).
Couple of things to note regarding the "squeak". Is it during the cast? The Abu's and Curado use the plastic break collars. I find that on my casts, towards the end of my cast, they start to whine or give a squeaking sound.
The one thing I found with all my casting reels, they are pretty thin on grease out of the box. Especially the Abu's, I've had to clean up some corrosion and re-lube the reels. Most of the time with my new reels, after a month of use and rinsing, I generally break them down to see what's going on inside and re-lube everything.
Hope this helps.
