Re Lubricating Oils. X.1434 X.3614

We are having a number of letters from manufacturers of lubricating oils recommending their products.

Have you any standard specifications for lubricating oils to be used on the car, giving approximate analysis and the viscosity at various temperatures?
If so, will you send me two or three copies for circulation here?
