I've been in the habit of slathering on a hefty supply of Quantum Hot Sauce grease on all the gears and inner workings of the reels I've cleaned in the past several years and yes, i'm sure it's good for the gears and keeps them from corrosion, etc. However, in one of my last Well, Duh moments of 2012, I realized that all the reels I've been redoing were running slow as molasses, albeit smoothly! I reasoned that just maybe that was because the grease I was slathering on had the viscosity of molasses! ...what a mind!
So, I broke down a couple little baitcasters that should have been running like tops and weren't...and I wiped off the excess grease and lubed the gears with Pflueger Speede oil (I'm sure any number of other oils are fine)...and voila...they run like speed demons! I'm sure that I would have NO problem in backlashing these reels in a heartbeat!
