Review on Swepco 101 SWEPCO Moly Grease by Vincent Blitz

Revainrating 5 out of 5

It really reduces friction and vibration!

I used it on a Mack truck driveshaft that has 4 universal joints and 2 splines. This significantly reduces the parasitic drag on the hinges and the splined shaft. I get smoother shifts, less torque, better fuel economy and overall less vibration in the cab. Yes, it's $20 if you want the best!

Pros
  • Best in its niche
Cons
  • I will add later
