Industrial Lubrication and Tribology
Article publication date: 1 March 1950
The discusssion was opened by Mr. A. T. Wilford (London Transport Executive) who referred first to Mr. Towle's statement “but the evidence is not vet sufficient to indicate whether heavy duty oil would show up better than those of the premium type in every day automobile use” and asked for the author's definition of “everyday automobile use”. London Transport had been carrying out large‐scale service tests with heavy duty type oils and the author's statement led him to wonder if they should not have tried premium oils before concentrating on the heavy duty oils.
