Abstract
A new laboratory test for evaluating the tendency of a gasoline, which may contain additives, to produce deposits during running of an engine involves the following steps: a tube is placed in the injector oven of a gas chromatograph; said tube is kept at a constant temperature in a constant flow of air; the gasoline or additive-containing gasoline to be evaluated is injected through said tube; and the quantity of deposits formed is determined by weighing said tube after dismantling.
