Here are some figures taken by the Vacuum Oil Company, showing that the torque required to start a car can be reduced by 40% when changing over from Mobiloil 'B' to Mobiloil 'A'. This is at 0°C. At lower temperatures the difference is still more marked. Hs{Lord Ernest Hives - Chair}/Rm.{William Robotham - Chief Engineer} | ||
