“Faultlessly lubricated with Valvoline.”
These ads for Valvoline motor oil are from 1945-48. Each ad featured a stylish lady standing next to a car. Her choice of outfit was then compared to her choice of motor oil, but seems more like the women were being likened to a car.
“Her car faultlessly lubricated with Valvoline… made exclusively from Pennsylvania crude oils… the world’s finest.”
The ad style changed a little towards the end of 1947 with more emphasis on “the girl” than “the car” in the imaginary.
