| -2- 3. The maximum T.E.L. content should not exceed that of D.T.D.230 specification. 4. As far as possible the specific gravity and viscosity should conform to those of the usual 100 octane fuels now in use. If you can send us say, 50 gallons, of 110 octane fuel we will endeavour to test it on one of our units as soon as possible. Yours faithfully, FOR ROLLS ROYCE LIMITED. | ||
