How many genericized trademarks do you currently use (read the OP)

Owners/sellers of older cars (1960s-80s) if they have a limited differential will say it has a “posi” rear end which is short for “Positraction” the name of Chevrolet’s LSD.

Even though in a Ford it is a “Traction-Loc”, Chrysler/Dodge/Plymouth used “Sure-Grip”, Pontiac’s has the “Safe-T-Track” and AMC called it a “Twin Grip”.

Just this past weekend at a car show I overheard a guy bragging about his Dodge with a “posi” rear end. Unless he swapped it out it, probably has a Sure-Grip differential.

The use of the slang term Crapper may, or may nor, be influenced by the work of this gentleman.

But this factoid is also the subject of some debate; here, for instance.

And yes, the trademark is still active.
