Another interesting review ("10301" is this grease),
It's grease, so performance is difficult to determine unless you can isolate it as THE variable that caused part failure. I use Lucas Oil 10301 on the universals and chassis points on all of my vehicles and equipment. The biggest test for me-- a 35 year old Gravely tractor that gets pumped full of 10301 four or five times per cutting season. This is an old, "worn-out" machine with thousands of hours on it. Seals, bearings, bushings, and most other rotating/sliding pieces have had hard lives. Even the slop from wear and tear, the metal-to-metal interfaces perform beautifully- no chatter, whining, or grinding. Before I converted to the 10301 (about 6 years ago), the spindles chattered horribly. They operate much more quietly (assuming with reduced friction) when packed with Lucas. The X-Tra Heavy Duty grease flows nicely out of the gun and it stays put really well- even where seals are direly worn (or holistically nonexistent). Other greases I tried in the past (natural and synthetic) were stringy and tended to sling everywhere. When they got warm, they got thin and migrated all over the place. The 10301 provides a really good blend of slippery and sticky that, at least for moderate RPM parts, even at higher temperatures, stays put.
