| -2- fact that we have run 3,000 miles and are continuing to run on ordinary oil when the car is used normally on the road, reduces the anxiety when owners cannot obtain a supply of Whitmore's. Owing to the fact that we have 100% results with Whitmore's on the dynamometer, we do not want to reduce the test in order to suit another oil unless it is necessary. We will report again in fourteen days what further progress has been made. Hs.{Lord Ernest Hives - Chair} | ||
