Clean threshing depends on keeping 
the cylinder revolving at normal speed— 
requires ample, dependable power. 
Maximum power depends on proper 
lubrication. 
The normal operating heat of a tractor 
engine is inevitably high, and the par¬ 
tial condensation on cylinder walls of 
the heavy fuels commonly used on trac¬ 
tors adds to the difficulties of lubrica¬ 
tion. Therefore, tractor engines re¬ 
quire a special oil which will resist this 
decomposition and diluting action of 
heat and fuel. Unless the lubricant 
maintains its body under these condi¬ 
tions, it will fail to give maximum pro¬ 
tection against wear. 
Socony Tractor Oil is manufactured 
especially to meet these requirements.
