WINTER-STARTING PROBLEM

SELECTION OF THE RIGHT FUEL AND THE KIGHT OIL. With the cold winter descending on home garages, chilling engines, the problem of how to get the easiest possible start is one that exercises the minds of most motorists. The problem is largely one of the selection of the right fuel and correct grade of oil. The fuel should be one known to possess easy starting qualities. Correct high volatility is an absolute essential, because the starting quality of a fuel depends almost entirely upon its volatility. i.e., its ability to vapourise at the correct speed. It is known to most motorists that petrol consists of groups of hydrocarbon molecules that evaporate at different temperatures; it is a scientific fact that the more molecules that vapourise at low temperatures, the greater will be the volatility of the whole fuel charge. It is in the selection of this group of hydro carbons and its extraction from the crude oil that the science of refining is displayed. Consequently the motorist should bo careful to get. a spirit that has this correct grouping of the boiling points, giving high volatlity. This will ensure that he will be able to get, to use a sporting phrase, a sPUt-second start, even on a cold and frosty morning. The next thing to remember is that there is nothing that cramps the style of a good starting fuel so much as an oil that is sluggish and lazy in cold weather. Choose an oil that is refined to be exceptionally fluid at low temperatures. Free flowing characteristics ensure that so necessary ready response of the engine to the self-starter. Not only should the motorist be careful to select the right brand for this purpose, but the correct grade is most essential. With some brands there is a grade for Arctic temperatures—where, for example, the thermometer registers 32 degrees Fahrenheit or lower. With a Motor Spirit such as Plume, in combination with a free-flowing, high-quality oil such as Mobiloil an easy start; ii f-’et. a split-second start may he looked forward to as almost a certainty.*
