It will be remembered that one of the strong points in favour of the loose liner cylinder block on Wraith was that distortion on the integral block was likely to cause excessive oil consumption. It is, therefore, interesting to note the attached two records of 25/30 oil consumptions from Cx.{Major Len W. Cox - Advertising Manager}, from which it will be observed that both these cars are doing over 3,000 miles to the gallon. Rm.{William Robotham - Chief Engineer} | ||
