It is only comparatively recently that the motoring public even at Home have had the advantage of being able to obtain the perfect Lubricating Oil "Shell Motor Oils were placed on the market as and when the results of years of collabora tive study and research by "Shell" Chemists and Engineers made possible the production of a lubricant superior to anything known previously.

Apparently the demand at Hom: and in Europe generally is enormous that it is nct until now that, following an increase of manufacturing facilities, an allo- ment for the use of motorists in Hongkong, has been made possible.
The fact that over fifty motor the firms at Home recommend use of Shell Oils in their ears (and included in these fifty "are such household names as Sun- beam, Standard, and Morris)-- would point to their constituting the Motor oil "par excellence." If all that the "Shell" people claim for these new oils is true, and knowing the universally accepted high opinion of other "Shell" products, I can see no reason to doubt it, then at last the perfect lubricant is at the disposal of motorists in Hongkong,

substantial increase in sales for the first twenty days of February over the same period last year is stated by Mr.
E. T. Strong, President of the Buick Motor Company to be an indication that his company and the industry in general are on the threshold of one of the greatest selling seasons the automobile business ever enjoyed. Such increases constitute an excellent "barometer of favorable business conditions. throughout the greater part of the world
Buick deliveries showed an increase during the first twenty days of February of nearly a thousand cars over a similar "We have found that au- period in 1926," Mr. Strong said. tomobile sales are ap accurate index of general business conditions."
"The value in using these sales figures as an index lies in the fact there has been nothing done to stimulate sales or create
demand which might be contrary to general conditions. The models now on the market are the ones introduced last August with the exception of two additional body styles which were added to the line later. Thus the upward trend in sales can be attributed to more favorable business conditions."
