A historical print article headlined What S.A.E. Men Were Told about the New Synthetic Lubes features three columns of text flanking an industrial illustration of a laboratory chemist holding a flask above a factory and a tanker truck. The text details a paper presented at the SAE annual meeting by J. C. Kratzer, D. H. Green, and D. B. Williams of Union Carbide divisions, introducing petroleum-free LB and 50-HB series lubricants. The water-insoluble LB-300 series, marketed experimentally in the East as Prestone Motor Oil at seventy-five cents per quart, delivers clean engine operation, easy cold starts, and minimal sludge compared to conventional oils.
