Hi - I recently bought a new utility trailer. When I popped off the rubber hub covers, I noticed they had grease fittings and were loaded with red grease. All the grease I have used in the past were a tan or black color.
Does the red color signify anything? Should I keep using red grease ? Or is it OK to mix and match greases? Who make the best red grease?
Also, how often would you recommend greasing the hubs?
Thanks in advance!
Red (the dye) is chosen by the manufacturer and is meaningless unless you happen to be colorblind
Mixing is OK provided you follow the tables ( all over the net and here) and don't mix certain types of thickeners and additives. Its always "best practice" to mechanically clean but not mandatory
No such thing as "best" grease- just volumes of individual opinions. Any grease that meets the requirements of your specific application
How often depends on your individual driving and loads for the trailer but in general low payload use under say 500 miles and not immersing- an annual repack should be more than adequate for a homeowner.
