Description
Full color 9 3/4″ x 13 3/4″ ad that is for Shell X-100 Premium Motor Oil. At the top of this ad it says 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 then contains a drawing that shows a smiling Shell Oil man holding the dipstick from a car that he has just checked the oil from. The ad text then says that “Shell X-100 Premium is 3 motor oils in one. It gives you unfailing lubrication at all engine temperatures. 1. When you start your engine, Shell X-100 Premium is like a LIGHT oil, flows freely to vital engine parts. 2. During warm-up, Shell X-100 Premium adjusts ‘thermostatically’ to a MEDIUM oil to give moving parts exactly the required lubrication. 3. When running hot, Shell X-100 Premium acts like a HEAVY oil, does not thin out dangerously at high speeds. 1 out of 2 cars are now using oil that is ‘worn out’. Samples of motor oil were taken from over 15,000 cars in a nationwide survey. Analysis of these samples showed that 54% were contaminated – in fact, worn out and unfit for use. Your oil may be worn out – that’s why it’s important for your Shell Dealer to make this check”.
