“CHALLENGE XS HEAVY DUTY MOTOR OIL”

 

“From These Distributors”

“YOU CAN GET THE SAME XTRA SERVICE MOTOR OIL THAT SERVED ‘ROUND THE WORLD”

“For a global war the oil industry produced an all-purpose lubricant… Army Specification 2-104B… The men who drove our motorized equipment know how this oil actually kept motors cleaner, never broke down under sweltering heat nor thickened in below-zero cold… You couldn’t get this type of lubricant before the war, but now you can. Ask for Anderson-Prichard’s Challenge XS motor oil.”

“YOU GET 6 SENSATIONAL VALUES”

1. HIGH FILM STRENGTH – greater protection against wear for cylinders, pistons and rings.
2. HIGH VISCOSITY INDEX – won’t thin out or break down under high temperatures or speeds.
3. NON-CORROSIVE. Contains inhibitors which protect bearings against corrosion.
4. BETTER PERFORMANCE through cleaner engine operation. Dissolves sludge, varnish and gum.
5. EASIER STARTING. Flows freely at zero or below. It’s weather proof!
6. ANALL-PURPOSE LUBRICANT. Not only an “approved diesel oil, but an oil with proven performance in trucks, tractors and passenger vehicles.
