Dear Mr. Robotham: When I was last at Derby you mentioned that there was a need for engine oil having unusual oiliness properties, and I have been making some experiments with our N.P. Oils in that direction. I should like to submit a special oil, Q.2719, equivalent in viscosity to our ADCOL N.P.X., or Mobiloil Arctic. Our own tests show that the load-carrying capacity of this special oil is about twice the normal. Yours sincerely, S.E. Bowrey | ||
