MG MGB and MGB GT Tech Talk
Fairly regularly there's a post about oil, but I don't think I've ever seen one on grease.
I'm going to grease my u-joints and drive shaft this weekend, and was pondering whether some of you who have been doing this for a long time have noticed any difference in grease. Or is grease just grease? If not, what brands are better?
(Before I bought an MG I had a real life that wasn't consumed with crazy questions like this one.....) :)
Yes, but this is a lot more fun.
I cant answer your question, but await replys.

I saw that John Twist was using a red grease....I was always taught to use black moly grease....wonder what the difference is.....
Great post.....I'd like to know what greases to use where.....or if black moly is the way to go....
Almost. I like the Valvoline products and they have a Good, Better and Best rating for their greases and they are priced appropriately. The Good is your basic Lithium complex grease. The red is for GM, Chrysler, Japanese and European cars. I use that on my valve cover gaskets to make a nice seal to the head (learned from John Twist btw). The Better is a partial synthetic and the Best is the full synthetic. The synthetics have a wider operating range, particularly in the bottom end. -65 degrees F instead of -40. Our cars see a lot of that don't they. LOL.
I've been using the synthetic for chassis and wheel bearings but any of them are probably OK. It is best not to mix the greases, some combinations can cut the lubrication value down, especially with wheel bearings. Always clean the bearings and grease them with clean grease. Cleanliness is next to Godliness with wheel bearings.
I used the Vavoline red grease for years, mostly because they gave it to me at the races, it's never let me down on the street or track, so I can atleast say that it has worked well for me.
I've used a red grease Mobile-1 synthetic for several years on all of my cars... no problems
I've always used the Kendall Super Blu. I think the different colors are just dye for merchandizing appeal. I do know if you get it on a white shirt, It doesn't come out!:)
I use Mobil1 chassis grease. it's red, whatever that means.
chassis grease would, I should think, be different from wheel bearing grease and so on. So I don't think I'd use the Mobil1 chassis grease on my wheel bearings.
I have used the house brand grease from CT for years and it has always done the job.
In the differential I use some oil from 1971. The good old HD 90. Still seems to do the job after all these years. We bought it in 5 gallon buckets to replace the differential and box oil in the FJ40 Toyota Landcruiser.
To answer the original question:
Is all grease created equal: NO.
Greases are rated for temperature and lubrication duties, ( ie Sliding , rolling or rotating ) and the resultant mix colour is an outcome of the components in it to help it do what it is intended to do.
The main aim of ALL greases is lubrication NOT colour cordination !
Check with any decent grease retailer for a guide for your intended particular application.
One point on wheel bearings: Clean the bearing of all old grease and pack HALF the bearing with grease.
This allow some expansion space for when the bearing heats up in normal operation.
Damaged seals are frequently the result of overpacked bearings.
