I have a tube of Kendall Super Blu, it is about 9 or 10 years old. I never used it, the metal seal is still in one end of the tube with the white cap at the other end. It still looks solid, there is no liquifying or separation in it that I can see. I didn't have need for it because not long after I bought it all that time ago, I got a truck that had "sealed for life" bushings, ball joints, U-joints, etc.
Now I am replacing the front lower ball joints on my truck and the new parts have grease fittings that I will happily refill at each oil change. Question is, is a 10 year old grease still OK to use? I checked around here, didn't find much info. I saw in a Google search 5 years is the oldest to use it and have it still work well, yet the same article said "5 years and maybe longer and most grease may still be in good enough condition to use".
I know it's only a few bucks for another tube of grease, but if I have it and it's still good why not just use it? I am confused and appreciate any help.
