Description
Black and white 9 3/4″ x 13 1/2″ ad for the Shell Oil Company that says that “In its first year TCP…the Greatest Gasoline Development in 31 years…has repowered 8 million engines”. The reason for this amazing fact is that “TCP, the Shell-discovered additive, blended into Shell Premium Gasoline, controls pre-ignition and spark plug fouling caused by lead and carbon deposits. Increases power up to 15%…spark plug life up to 150%”. This is an informative ad having no pictures other than a small Shell insignia at the bottom right. The ad says that “An entirely new gasoline, Shell Premium Gasoline with TCP, was first introduced to American motorists 12 months ago. Because it overcomes the greatest cause of power and fuel loss affecting today’s engines, it was hailed as the greatest fuel development sinde the introduction of tetraethyl lead in gasoline back in 1922. In the first year following its announcement, Shell Premium with TCP has met with outstanding success. It has repowered more than 8 million engines”.
