Blender Blade with Bottom Base and Sealing Rubber Gasket O Ring For Oster

This blade was to replace the original in my Oster blender. When using it the first time I noticed the blades were not "shaped" like the original Oster blades and didn't make smoothies with ice as well. It took much longer and some pieces of ice were still in the drink. Then after several uses I started to notice a strange black oily material coming out of the hole that fits into the motor base. At first this was just annoying but as the amount of metal, commercial oil smelling gunk increased and was all over my kitchen counters I was ready to throw everything out. One last try today and this black gunk went into my smoothie making it black and smelling horrible. Blender container was disassembled and cleaned after each use with everything replaced tight and correct. Looks like it's time for a new blender even though the motor and glass food container are perfect. Doesn't work without a blade and bottom base.
