Macmillan Oil Ad and Poster Collection
Macmillan Oil Ad and Poster Collection: MOCA was founded by Robert Fritz in 1937 as one of the regional lubricant distributors of the Macmillan Ring-Free Oil Company. Macmillan Ring-Free began in 1923 and built its reputation with an “ahead of its time” formulation unusually high in natural detergency and extreme pressure properties. Introduced at a time when most oil companies and auto designers felt that any mineral oil would lubricate just fine, Macmillan Ring-Free proved the advantages of performance products. Not only would Ring-Free protect against deposit formulation, sludge, and other contaminants. It would also free up sticky rings, valves, and pistons, which is how the name developed.
