| Y56 21158 No. .2. V.O.Co., Ltd., to As regards the test of Gargoyle Hypoid Gear Lubricant in France, we normally recommend draining the oil every 5,000 miles. It is felt that a good deal of neglect occurs in regard to transmission lubrication of Motor Cars generally and while it may not be possible to get all Motorists to change every 5,000 miles a recommendation of this kind does definitely tend to induce the Motorist to pay attention to this feature more frequently than in the past.
