- If you own a Mercedes you will find that you need a Mercedes approved grease FOR WHEEL BEARINGS!! Let’s get a better understanding of what wheel bearings are made out of. METAL! And only a few manufactures make wheel bearings. SO what does metal like? Lubrication, plain and simple.

Now that we know that, let’s see what makes a good lubrication for Metal wheel bearings. Mercedes Benz is no exception.
We have ratings, ingredients, temperature tolerances; wash out ratings, Composition, and so on.
For automotive purposes we need to look at a few ratings by the
NLGI which stands for the National Lubricating Grease Institute.
SO usually you will see a number after NLGI. Most likely it will be #1, 2, or 3. Most automotive bearing greases are #2. The number represents the hardness of the grease. #000 is closer to a fluid where as #6 is more like a solid. Think of cheese. #2 is closer to the consistency of warm peanut butter. This is good for protection and coefficient of friction.
Another rating to look for is GC-LB which indicates whether the grease is acceptable for chassis and disk brake applications (wheel bearings). (LB) meaning it is acceptable for Chassis and (GC) meaning it is acceptable for wheel- bearings
Next we'll look at ingredients: there is lithium, moly, aluminum and so on. For most automotive wheel bearing applications lithium is the best choice. There is also synthetic greases which offer high heat ranges and added protection
NOW the big one, COLOR, Mercedes grease is green. Most other greases are RED. SO what’s the difference??? Green, red, white, and purple are usually made with lithium.
White Gray-black is aluminum and gray-black is lithium with moly
So your green Mercedes grease isn't magical except for the PRICE. $6.00 dollars for 150 grams compared to $5-10 dollars for 1lb of the same grease.
So, to sum it up. When looking for chassis- wheel-bearing grease, pay attention to NLGI and LB GC ratings, whether its lithium based, and the operating temp of the grease. Everything else will be extra goodies that the manufacture adds like rust protection, thickeners, antiwear additives ect.
So at the end of the day the most important thing is that you pack your bearings correctly and that there is plenty of grease in the hub assembly, and that you're using the CORRECT grease for the right application. I hope this helps. I have provided some links in the description below to help you with your buying decisions.

Sorry, not meaning to bash but there is a lack of "control" in your testing.
Test 1: the sliding was base on feel? You were wearing gloves. Science? Are you testing Sex Lube? Where is the measurement of friction or a standard.
Test 2: Temp was measured with a temp gun. You used such a small bit of grease that you were measuring the temp. of the metal ruler. The temperatures were much higher than what you measured. SuperLube spec sheet says it is good to 450F so, I do not believe at 311F it would be on fire. There was time lapse from the time the grease fell off and some readings came faster than others. You could of put the grease same amount in a beaker and heated until it melted with a thermometer in the grease for this test
Test 3: You were not consistent with time, pressure and distance of the water. The size of the blob of grease and how it is applied to the ruler would be factors on how it would stay on.
All of these tests to not really translate well for what you are going to use the grease for. It was an interesting vid but I would not use any information here to make my decision on which grease to use for bearings.
Hello MrCuckoobox! Thanks for your feedback. I'm not sure if you watched all 50 minutes of this video, but I did say that these test aren't super scientific, (but are still scientific to some degree) and that they were just some things that I thought would be cool to try. It's best to treat this test as a stand alone test and not compare it to other test methods. Going into this test I thought all the greases would perform the same and that these test would not provide much information. To my surprise a lot of the greases behaved in very different ways in each category. So, regardless of how scientific these test were, they still revealed some valuable information about each brand of grease. Again, thanks for watching and commenting, and I'll keep your feedback in mind when making more future test videos. Cheers!
Glad you made this I would have thought the green renolit was the same as the febi. But the febi is probably the same thing as the genuine mercedes branded one. I ordered some new bearings but they come with a much thinner blue grease preinstalled. I think it's similar to the renolit that you used. I was wondering if I can combine the oem mercedes green with the blue or if these will contaminate eachother. There are so many different types of grease and different materials I am not sure what goes with what. I just know some make the oil completely dry up when combined.
Temp range?? under hard driving conditions/racing good brake systems handle 400°C to 600°C that grease will barely be good enough for regular driving i dont wanna repack replace bearings if i have sticking brake issues, the bearings are built right into the brake rotors on some vehicles, and by design sticking calipers is almost guaranteed, some are even dragging building heat when new!!
Hey everyone! Let me know what you think about the greases tested in this video. Did you change your mind about a certain grease after watching this video? I'd love to hear from everyone in the comments below!
I use the amsoil grease from my grease gun
Where can I get Renolit replex 2??
Hello Shane Christopher! You can purchase Fuchs Grease off of Ebay. Here is a link. www.ebay.com/p/18012572382
The seller is selling in bulk, but if you ask, they might sell individually. 1 tube will be enough to service your bearings many times over.
The grease that I'm using in my car is from this company in Canada. store.dcddesign.com/fuchs-renolit-grease-single-tube
It's amazing and I used it for the drive from California to Georgia (about 2,000 miles). Grease is holding up great!
Hope this helps. Cheers
Got my volume turned up to 11 and I can't make out what you're saying.
