011-engined Vehicle A NOIIIER triumph for a Gal ns New World's .1-1, commercial-type oil engine
Record w-as won at Mont1h6ry last
Saturday, when Captain G. Eyston, using a car equipped with an A.E.C. engine as employed on London buses, railcars, etc., broke his own world's 24-hour record for oil-engined cars by covering over 2,300 miles at just over 97 m.p.h. This is actually farther than the distance from London to Newfoundland. During the'run he covered 1000 miles at about 99.5 m.p.h. 'Only a few days before he broke the worlds hour record at 1016 m.p.h. Incidentally, he employed Castro! oil and the oil-fuel cost for the long run was about 7s. per 100 Miles.

Tonnage of Periodicals A FEW days ago the'Minister Of Transport was a guest at the banquet of the Periodical Proprietors' Association. He expressed himself as being much impressed by the figures relating to the tonnage of publications ,carried annually, this being 250,000. He stated that it was the aim of the Government progressively to improve the conditions under which this precious freight is conveyed, just as he hoped that it would be the aim of transport undertakings to quote the proprietors ever cheaper rates. 'Oh, Mr. Hore-Belisha! We trust that it is not to be inferred from this that you will give encouragement to the general cutting of rates, but perhaps you had the railways in mind.. Carried Annually is 250,000 How Drivers Know IIRING a speed case a few They Are Being A-, days ago a police officer Timed told the magistrate how com mercial-vehicle drivers can tell when they .are being followed by police cars. If the driver sees a car behind him he usually waves it on, and if he be not overtaken by the vehicle he presumes that his speed is being checked.
fhe Effect of SOME important points con Various Metals on cerning the influence of Lubricants . . copper, lead and tin upon the dilution of lubricating oils are contained in a brochure just published by the International Tin Research and Development Council. The effects were obtained by heating samples of oils in glass basins for two months at temperatures akin to those Occurring in practice. Thin films of the metals under test were produced on glass plates by evaporation under high vacuum, and these were immersed in the oils. The films were so thin as to be transparent to a degree, any thinning by corrosion increasing this quality and being used as a measure. It was found that the viscosity, surface
tension and acidity of the oils were not influenced by the metal present, but sludge formation was strongly stimulated by copper, whilst tin and lead had the opposite effect. Sludge greatly influences lubrication. The differences in the amount obtained from various oils proved to be remarkable. Copper was also strongly attacked, but the other two metals were protected by the film of reaction products. Another finding was that oil stored in an open can for some months was decidedly more corrosive than oil fresh from a sealed can A similar effect was found by opening a can, resealing it, and storing the oil for a month.
A Little Attention May Save Time and
Money
I T has been stated by an electric-vehicle concern that in 90 per cent. of the motors returned to it extensive damage has been caused by neglect. This is because the battery-electric vehicle asks for so little in the way of maintenance, and, like the humble beggar, may get nothing. The complete inspection of a vehicle motor should not take more than 20 minutes and may save a repair bill of perhaps £.20. A Little Attention May Save Time and
