Best grease

Re: Best grease

I am by no means a "Grease Expert" BUT as an aircraft engineer, I have had to perform multiple grease research projects. Their are two main differences in grease, the base component and thickeners. Things like clay, calcium soap and lithium are thickeners with the bases being mineral , synthetic or both. Additives such as molybdenum disulphide can make a grease perform in a wider range of tasks. The additives and bases have to be compatible with the seals and metals they contact as well as the enviroment they operate in. Some operate better at low temps and will wash out when heated or some only work well at high temps and are too thick to provide lubricity at cooler temps. The "Right Grease" is the one you choose based on reading the label. Usually you dont want to use a clay thickened grease on a surface exposed to high moisture but it might be just the thing for a dry enclosed area. If its rated to NLGI 2 and water resistant you should be good to go just remember none are waterPROOF!

Best and most correct post yet. A close friend of mine has worked for 25 years at SKF (largest bearing manufacturer in the world) and he gave me the same lesson. Let me add, you do not want to mix greases with different formulations as they may react with each other chemically and can break down the compounds whereby you end up with anything but grease. Sticking to one brand and type is good advice.

Re: Best grease

Anyone ever use Bel-Ray waterproof grease?
That is some sticky stuff right there and holds up better to water than any other grease I have ever used, including Amsoil waterproof grease, which is also great grease imo.
I use both, depending on application(Bel-Ray comes in a tub, Amsoil in a tube) on everything from wheel bearings, snowmobile shafts/lube points, atv's, dirtbikes, utility trailers, boat trailers, ball joints, drive shafts etc and have never had a failure, not once..........Irv964
