A new engine‐testing and development laboratory

There are several hundred lubrication oil companies operating in Great Britain today, and a number of these have been operating for fifty years or more. And yet, less than twenty years ago, most of these companies were carrying on their business in the same way as when they began. With the coming of the motor car and motor vehicle in large numbers, most of them turned their attentions to producing motor oils, and in those early days, little science was required to blend very satisfactory grades. Even in the industrial field, bearing clearances were very great by modern standards, and perhaps it may be said that the principal duty of the lubricant was to fill up these gaps.
