Q. What is the basic rule to observe to secure efficient lubrication?

A. First of all, the motorist must be prepared to buy and use only the best oils and greases, especially for motor lubrication. This assurance is obtained by buying the product of only reputable manufacturers of lubricants and paying enough for them to procure material of the proper quality. The instructions given by most makers of cars for lubrication should be followed to the letter and the greases recommended by them should be used in preference to those the motorist might select for himself.

A comprehensive lubrication chart showing the important points demanding lubrication on a Chalmers chassis is clearly outlined at Fig. 276 while the lubrication chart prepared by the engineers of the Overland Company is presented in the form of a folding plate, Fig. 276a.

The schedule of lubrication appended applies to the Chalmers chassis but as this is typical of standard design the instructions given can be followed to advantage in other cars of similar construction.
