Do not make the

mistake of thinking all greases are compatible, they aren't. Don't

mix lithium and molybdenum greases.

Lithium grease is the standard stuff you'd get in a tube at the auto parts store. Moly is an additive to multiple base greases but most often, moly grease is the same lithium grease except they just added some moly as an anti-wear additive.

There is nothing wrong with mixing the standards lithium based moly grease at the auto parts or hardware store with standard lithium grease without moly. Of course if you need moly protection, mixing will reduce that protection, or if you don't, you may have overpaid for the moly grease.

I use a lot of Lucas red and tacky or heavy duty on my heavy equipment. Mostly because it's easy to get locally. I keep one grease gun with green mystic just to grease the turntable bearing on my excavator. Schaffers is an incredibly good grease but a pain in the *** to buy for me. I bought a machine that had a few tubes of Mobil in the toolbox. That was probably the best grease I ever used for heavy equipment pins.

When it's all said and done, dollar for dollar I think the average person will find red mystic hard to beat.

I use Steelco Red Crown on slip yokes and the like. I don't know how it compares to Red and Tacky but I'm happy with it. For normal automotive grease I use Carquest Moly EP.

Only zerks are on my garden tractor... so Lucas Red 'N Tacky works fine. I've also used Lucas HD (green polyurea) grease for some higher-temp stuff or high-speed BBs. I just don't care for its consistency (thin mayo and not sticky).

On my motorcycles I used Belray Waterproof grease (tub).

Funny topic. Just like motor oil. If grand daddy said this, then daddy, now..its you. LOL
Oil and grease and firearms and tools and small block v8's is such a prideful thing. And funny.

To some of the above who act like mixing grease will destroy said equipment...I couldn't stop laughing.

If you are going to mix lithium with wheel bearing grease then yes there could be an issue.

However if you are mixing tub or tube grease into components that has something else what will happen?

NOTHING.

Just like mixing motor oils. Now I know someone in some far away place and some far away land at some different time had a rod bearing go bad and it JUST HAS to be because 8 months prior he need one quart of oil and could only find brand X while his engine had Brand y in it. So therefore it absolutley must be due to the mixing of that one quart in the crank case, right?
Ha ha ha ha ha ha ha ha

Buy whatever grease makes you feel all warm and fuzzy. Use it.

Mixing any wheel bearing type grease means nothing other than you are now greased back up and ready to roll. All grease provided its the same type plays well with others.

In other words don't apply lithium grease or Crisco to something needing wheel bearing grease and the reverse also applys.

Happy greasing

Depends what you're greasing...metal rubbing on metal, I generally use a moly disulfide grease.

metal on plastic, silicone based (like superlube)

metal roller elements (like wheel bearings) red 'n tacky

I've used the Bel-Ray on all wheel bearings for years. Especially boat trailers.

There are many types and grades for each application. So, to say one Grease fits all is not the correct philosophy. Start by looking at what you will be lubricating, and your budget. Heavy earthmoving equipment for example, performs best with a grease that is high in moly additive content. We use a 5% moly grease that meets Caterpillar specifications(Mobil, or DA lubricants). For chassis applications, moly isn't necessary, but is ok. I like Valvoline ceroline for chassis applications. So, look at what you are doing first. Look at what grease is suitable for the application. As far as compatibility, lubricant manufacturers RECOMMEND cleaning all residue of grease when switching types. Some aren't compatible. When I try different kinds, I just try to flush out the old stuff. My personal favorite grease in terms of tackiness is chemsearch aluminum complex red. I can't seem to find it anywhere though. So, yes it does matter what type of grease is in your guns.

Yea for sure. I have blue Mobil polyrex for electric motors and Castrol contractors special for metal on metal. Both have their own grease guns

grease is not grease. people who say that use no logic what so ever. the majority of grease you find in the autoparts stores is lithium based a few are polyurea and some are calcium sulfonate. but if you go into a parts store and get the cheapest ****, guess what has the highest volume? lithium, so guess what is cheapest? lithium, so guess what all the different brands they have been using is? lithium. so no wonder they havent had any issues. same guys who rattle on lug nuts without torquing them

^ You had me for a while but the moment you wrote "cheapest ****" you went off on a tangent. Cheap is a virtue instead of overpaying based on delusions that more expensive is always better.

Paying for something exotic when it has no benefit is madness, when you realize that best for some extreme application is not your application.

Lithium grease is sold in auto parts stores because it's applicable to the tasks involved in automotive lubrication, nothing "****" about it. Granted, for high pressure metal on metal you're probably better off paying $2 more for the same "****" with a little moly added.

Grease is grease just like oil is oil. gear oil is exactly the same as motor oil right. Some grease is so thin that you can barely put it it a grease gun ie. corn head grease, some types of industrial moly is so thick that you can't pump it through a hand grease gun

Wheel bearing grease and lithium are total compatible. It just that that little tub that says wheel bearing grease is handy for packing bearings, where if the bearing cap or hub has a zerk fitting you grab the grease gun with the lithium complex grease in it

What I don't understand is lithium complex and polyurea grease, both available everywhere. Some people say it is compatible, some say never mix the two. Don't really know the advantage of the polyurea over the lithium

From the machinery lubrication article:

The compatibility of polyurea greases with soap-thickened greases is probably the most debated area of grease compatibility today. Greases based on simple lithium soaps (lithium stearate or lithium 12-hydroxystearate) and lithium complex soaps (containing simple soap and a complexing agent, such as lithium azelate) may or may not be compatible with polyurea greases. This is because of the wide variety of materials that can be reacted to form a thickener that is termed polyurea. Some polyurea thickeners are completely compatible with lithium and lithium complex thickeners, while other polyurea thickeners are definitely incompatible with the lithium and lithium complex thickeners.​



Polyurea thickeners are typically used in high speed rolling element bearings (electric motors most commonly). Note that an automotive wheel bearing is not a high speed application based on the roller speeds.

Another article from the same source goes into the characteristics of the thickeners and the base oils. Getting deeper into the engineering here, but it shows what really goes into selecting lubricants for industrial equipment.

We used to use this stuff made by Kluber for ball screws. It had the thickness of honey. Expensive stuff. I didn't know anything and tried it in ball joints. Ate the rubber and oozed out.

For most people and uses, a NLGI #2 lithium-based EP grease is all you need. When it comes to lithium-based greases with moly added - they are good for sliding parts but not so good for rolling parts because moly grease is too slick for bearings to roll properly. That's why you will see most "wheel bearing" grease does not contain moly. Also, what makes a "wheel bearing" grease different from a regular lithium grease is that has a higher drop point so it can withstand higher temperatures in situations where the wheel bearing is contained within the brake rotor or drum, as opposed to a unit bearing.

Depending on use I use either EP2 or MP3 for cartridges, makes include Gulf EP2 grease, or Fuchs MP3 or EP2,
Rocal Saphire blue is also very good, can be costly,

anything else I use Lithium based, Brands such as Carlube

Regarding mixing wheel bearing grease and lithium. The lithium complex grease i buy is from a Exxon/Esso commercial oil place which has a higher temperature rating than the cheapest lithium grease at the parts store.

If you only have a few types of vehicles, there are tons of specialty oil and grease company's out there. Your boat trailer that goes into salt water probably needs a different grease than your sports car with the large disc brake on it

I think Im going to just use Lucas Xtreme Duty green grease on everything for my dozer, bobcat, trailers, and 4x4 toys. That way I dont have to have 2 different guns and remember what I have in each. Hopefully it doesnt turn to cement and i can just grease more frequently until the old grease completely is pushed out. Instead of just wasting the grease and pushing it all out at once.

I just use a grease suitable for the application. Using the correct type for me is more important than sourcing some exotic fancy grease Joe bloe on the innernet recommended.

This works. Only place we specialize a little is some Moly when I have it for pin, bush and suspension. I ran out a while back, I bought a box of each on sale and after I left the store regretted not getting 2 of each. Someone came in with some tube of Traveler general, I was going to look at the ratings. It was listed as general, not severe for use where routine greasing to push contamination was normal. Not sure how much less severe duty it is?

I use what ever happens to be in the grease gun at the moment.

My requirements are simple, just stop the squeak.

Yes, lots of grease is simply to stop pin seizure, wear reduction may only be a secondary concern. We work a lot on the same equipment. I really do think the moly 3 is worth it in severe, dirt and grime. Seems to hang in there better.

This is an old story. My partner tells of working in the Petrocanada refinery. In an oil refinery the main machinery is pumps. The pumps are powered by electric motor directly though a coupling. Fauk usually. Here he is working for the largest oil company in Canada and what do they use in the spring coupling, Mobil 101 , a moly grease.

just got the lock n lube xl and tried it out, i think its bleh grabbed on to 80 percent of the zerks. too long on 2. might have to return it if i can with amazon and buy the regular size one.

Look on the tube and it should say NLGI #2 for most cases and GC-LB, as that tells you the GC is rated for heavy duty wheel bearing use and LB is rated for chassis lube then you should be covered. Castrol Syntec branded grease was on sale on the web at PepBoys because they changed the name and they are selling it for $2.59 a tube which is a gift so I bought a box.

The Lucas Oil Red and Tacky is listed as GC LB, so I'm ordering some for general wheel bearing and suspension lube.

Do I need something else for CV joints, U-joints, and other high-speed bearings? If so, I like the Redline CV-2 synthetic high performance grease. Not cheap but highly rated. https://www.redlineoil.com/cv-2-grease

I use Lucas Xtra Heavy Duty on everything from riding mower to my RV. It seemed like to met all the requirements for everything I have. Red n Tacky looked good, but I something swayed me to the green stuff. It has been doing a great job for many years now. Having one grease that works on everything is great. I am not sure if I would use it for marine applications, eventhough it would probably be okay.
