| -2- Hs{Lord Ernest Hives - Chair}/Lid.{A. J. Lidsey}7/MA.18.5.32.contd Up to date the following mileage has been completed on 'KKL' oil in Exptl Dept cars and no drawbacks have been encountered. 22-KX. (Gear box) - 7638 miles. 20-KX. (Gear box) - 4,200 miles. 19-KX. (Gear box) - 1526 miles. In addition all Exptl 20/25HP cars are now being run with 'KKL' in the gear box (synchromesh) and rear axle, we should therefore soon be in a position to recommend this oil as an alternative to Price's Amber 'A'.
