Whatever they used in it is probably good enough.
Generally unless you have a specific reason to replace the grease (contamination, overheated causing liquefaction or other breakdown, etc.), I would recommend just leaving it alone as it is. If you replace it you should completely clean out all remnants of the old stuff, especially if you use something different to replace it with. It's possible for one grease to contaminate another and cause it to not do what it is supposed to anymore.
That said, I've used the red high-temperature grease for automotive wheel bearings and such, whenever I've replaced grease in something. Just remember that the stickier it is, less flowing, the more friction it adds (but it is more likely to stay in the places it's needed when stuff gets hot).
