THINNER ENGINE OILS

Purchasers, of new car; will find that'many: makers are now recommending comparatively thin oil for engine lubrication. To motorists who have been brought up to believe that only thick oil is good oil, this change in practice may " come as a surprise. The explanation is, however, simple; experienced- engineers have realised for a long time that thin, or lighter oils offer many advantages over thick. It has, for- instance, always been known that:thin .oil, owing to its greater fluidity, would reduce engine friction. It has also been .proved to reduce petrol consumption and to cut down cylinder wear. The difficulty has been to produce an oii which is thin when cold, and hot too thin when hot. Light oils have been developed which overcome this difficulty, and the car manufacturers recommend their use. The French J in their logical way, are ever making small but extremely useful improvements contributing to Safety First. The latest is to increase the candle-power, of street lights near pedestrian Crossings, so that the studs shine up nicely at night, and the pedestrian crossing can be seen easily. Another is to lay non-skid road surface on the approach to such crossings. An important arid far-reaching legal decision was recently given in England as the outcome of an action by a motor. Ist against a pedestrian who was held responsible for an accident caused through her careless walking. The motorist stated that a woman ran from a .house, in front of his car. He endeavoured to avoid her, but could not. The car hit a bank at the roadside, the driver suffering sprains, bruises, and shock. Suing the pedestrian, he was awarded £100 damages. I
