That could be, and most likely is true. The story I got (
back in the day) was as I stated. It was also rumored that applying an
STP decal to a window in your car/truck resulted in an additional 10 horsepower at a minimum... To say nothing of the
'COOL' factor.

Hence the application of an
STP decal on the window of my '48 TuDor Sedan back in '65...
