I believe OMC renamed it to "Premium Blend".

 

[skinnydriver]

is that a omc brand and ive also heard a t f works is this true

Yes that is OMC brand. Even though one of mine isn't electric shift, Type C was required for mine.
Premium is the replacement and likely better than Type C.
To my knowledge Type C isn't produced any longer.
