I guess they don't make them like they used to. My Sears floor jack is about 25years old and still works like the day it was bought. I am almost embarrassed to say I have never checked, added, or replaced the fluid. I have lubed the wheels a few times though. Coincidently, my neighbor has the exact same jack and his experience is the same as mine.
While shopping online for a new or used reciprocating saw, there was a Craftsman brand on ebay. Fine print said "made in China". I passed and bought Milwaukee.... are they made in China too?
Fine print on jack says "Made in Japan".
