Only when your tractor develops full 
power from dawn to dark can you give 
yourself a fair chance to cultivate large 
acreage early and take in big crops. 
This day-in-and-day-out tractor de¬ 
pendability is governed by lubrication. 
A careful study of tractor engine design, 
the frictional wear and Jieating effects 
of heavy duty tractor service, and many 
other factors, have led to the develop¬ 
ment of Socony Tractor Oil . It is ap¬ 
proved and recommended for tractor 
use by the leading tractor manufac¬ 
turers. 
For the protection of your tractor 
against wear, resulting in rapid depre¬ 
ciation—to get every possible ounce of 
power out of the fuel—to keep your trac¬ 
tor working at maximum efficiency— 
buy Socony Oils , Greases and Fuels 
where you see the Socony Sign . 
There is a SOCONY LUBRICANT 
of the right consistency for every 
mechanical need.
