My dad gave me his old Sears compressor, and I consider it to be a necessary tool in any mans garage. I use it for inflating tires, removing lug nuts, painting, cleaning, nailing siding and roofing. It's so useful that I recently installed a hose reel so that I don't have to fuss with putting away tangled hose all the time.
Now that we're on the subject, how do I change the oil on this thing? Is it simply opening the lower bolt to drain, and filling from the upper bolt? What oil should I fill it with?
