I didn't know that...

While reading the new issue of Road & Track, I noticed an ad for Armour All with the slogan "The Racers Edge", which of course used to be STP's slogan.

A quick look at the fine print shows "Armour All/STP" corp.

I didn't know that.
Is this new or is it just me that hasn't paid any attention to it until I bought a Studebaker?

It dosen't.
It stands for"scientifically tested product.

[Skip Lackie]

My recollection is "Scientifically Treated Petroleum".

The S in STP, AFAIK, never stood for Studebaker. IIRC, STP did have different meanings at different periods. I believe that both Skip and Transtar56 are correct, with Skip's answer being the earlier meaning. I believe that STP was originally a German company. I am only going on memory. I guess that someone could look all of this up if they are interested.
