Interesting thread.
I've been using Mystik JT-6 Multi-Purpose High Temperature Grease (Red)to lubricate everything. Bearings, grease fittings & towing ball & other hitch hardware.
I've noticed that on long, cross-country towing trips that the grease on the ball would dry out to a black, very thick substance that didn't look like it would lubricate, at all.
On one of my trips, I stopped in at a travel trailer dealership & bought a "Hitch Ball Lube", "Towpower" from Reese, part # 58117 (4 oz. jar). On the jar it says,*White Grease, *Odorless, **Non-toxic, *Will Not Breakdown, *Reduces Friction, *Superior Lubricant.
This stuff is a bit pricey but, it hasn't broken down, at all. At the end of a trip, it's still very greasy, unlike the Mystik JT-6 Grease. Also, a 4 oz. jar looks like it will last for a long time. A little goes along way with this stuff.
Mystik JT-6 Grease is supposed to be a high quality grease & i've never had any problems with it but, it doesn't even come close to the Reese Towpower white grease.
Normally, I wouldn't spend the money for the Reese grease but, I'm sure glad I did this time.
For short trips, the Mystik JT-6 Grease would be just fine but, it wears out quickly. Many higher-end repair shops use Mystik products & consider them to be of premium quality.
I use the JT-6 on suspension parts & to re-pack my trailer bearings, annually. The bearing grease is mostly still red with some of it starting to darken when I change it.
I'm beginning to wonder if there is a better product for me to use. Any thoughts, suggestions or recommendations would be appreciated.
