I must be bored today in addition to the cabin fever.
I was reading on a contractor forum about what grease guys are using on their pins. I have felt that my Valvoline Durablend was too thin, it is for high temp/wheel bearing applications.
What kind of grease do you recommend on high load bearing/slow moving parts?
I have also heard you are not supposed to mix greases, why or why not?

I run a molly based grease, seems to work well for me, but its really messy! Its a grey colour and stains your skin from the molly in it....
I figure grease is grease, as long as its suited for your weather. Some grease can freeze in the winter, if it does you need to use better stuff! frozen grease is like having no grease to start with.
Not sure why they say not to mix grease, but to grease properly they say to keep pumping grease in till you see fresh stuff come out, that way you know any gunk that was in there has now been flushed out as its all fresh now.

Check out these links. The first one deals grease compatibility and the second one is every thing you ever wanted to know about lubrication.

Actually I think the grease Bobcat sells is a good grease for the money. I like the mid range stuff better than the extreme though.

I use a lithium based grease (lithoplex). That stuff sticks to anything. Very Tacky. It definitely won't just wash away.

Low Temp Lubriplate. It's white and a real good all round grease. Also reasonably priced.

What does the Bobcat stuff sell for?
The bobcat supreme grease is 3.67 by the single tube which may seem high but I have paid 5 or 6 bucks at napa for a good waterproof grease. bobcat also has a cheaper type and a more expensive one. The cheap auto chassis grease we used to buy seems to wash out or whatever it does not have any body or tack to it. other bobcat dealers may be higher or lower also.

I would reccomend a good quality Moly grease. The moly will continue to provide lubrication even if you overshoot a scheduled lube (Like I would ever do that :) ) You should not mix greases as some are thickened with different materials, when the different thickeners get together, sometimes they don't react well, or hold their properties. They may get thicker, or thinner, or clump or something else, but generally the properties will degrade. When you change over, you will want to pump through the grease until you see new grease coming through. I would reccomend speaking with a local oil distributor and using what they have (or a good supply house) Personally, I am using Shell Retinax with Moly I think it was, but have also used the Texaco Starplex depending on who liked me the most at the time. :) The biggest thing with greasing for me is to make sure it gets done.

I picked up a case of Bobcat Premium #2 Grease today. It was 3.30 a tube. I was there anyway picking up some spring maint items.
