Description
Full color 9 1/2″ x 13″ ad that talks about the importance of Changing your Oil as often as recommended, and when you do, replace it with Shell X-100. There is a picture of a Shell attendant checking the oil on the dipstick of a customer’s car and trying to determine how it looks. The headline claims that “The most important 30 seconds in the life of your car is when I check the oil level and ask: ‘When did you last change your oil?'”. The ad goes on to say that “1 out of 2 cars are now using oil that is ‘worn out'”. The ad explains the claim about this oil being 3 Motor Oils in 1 by gently explaining how a multi-grade oil works.
