("Early in the new century, Wakefield took a personal interest in two sporty new motorized contraptions – the automobile and the airplane. The company started developing lubricants especially for these new engines, which needed oils that were runny enough to work from cold at start-up and thick enough to keep working at very high temperatures. Wakefield researchers found that adding a measure of castor oil, a vegetable oil made from castor beans, did the trick nicely. They called the new product 'Castrol' ")
