| described. With Mobile A the starting of the Bentley has been quite O.K. but we have not left it out all night in zero weather yet. They are most particular about oils here, mobile A seems largely used and for extreme cold a 50% mixture of Kerosine & this oil which does not sound very sound practice. However at 20 below which they have recently had in Springfield, something abnormal has to be done to get the Car started. They are having acute trouble on the Phantom, with Silencer Corrosion since starting to use lead. We saw the Ethyl Chief Chemist in N.Y. and arranged to meet him, Heron & Jardine in Detroit, hence our request for summary of valve tests. So far Ethyl Corporation can do nothing to help us as they cannot reproduce engine results in the laboratory by any means | ||
