Description
Full color 9 1/2″ x 13 1/2″ ad that tries to explain why Pennzoil is considered to be The Lonely Oil. There is a picture of a row of massive stone columns with a single can of Pennzoil placed between two of them and a soldier, several columns down, seeming to stand guard. It explains why it is not as widely known as other brands, because it has not been developed by a large family of gas stations. It may be available through them because of how good it is but it is not advertised as their own products are. They call it “the grandfather of motor oils” because it has been developed by three generations of research in oil making. Using the combination of Pennsylvania motor oil and the additive Z-7 makes it as good as you can get.
