SOCONY TRACTOR OIL 
FOR CYLINDER WALLS 
TRACTOR 
INSURANCE 
It requires a special oil to stand the high 
operating heat traction engines develop— 
especially when kerosene oil is the fuel. 
Only a lubricant made for tractor use can 
insure steady, dependable work and afford 
suitable protection against destructive 
friction. 
SO-CO-NY 
Tractor Engine Oil 
is the special oil that the largest farm 
tractor manufacturers recommend. It 
stands the high cylinder heat — doesn't 
break down and run thin—keeps compres¬ 
sion right. Oil-cushions cylinders, valves, 
and bearings, with a protecting film that 
insures satisfactory operation at the least 
annual cost for overhauling and repairs. 
Keeps the Cylinder Walls as Smooth as Glass. 
So-CO-ny Gas Engine Tractor Oil maintains a 
cushioning oil film that keeps cylinder walls like new 
—free from scoring and scratches that cause poor 
compression, wasted power, impaired efficiency for 
work and a lowered sale or exchange value for your 
tractor. It’s the oil that keeps tractor engines fit. 
Use Polarine Gear Oil for transmission gears, 
universal joints and parts requiring a heavier bodied 
oil. It will Iveep the gears operating quietly with 
the least possible wear. 
Fill the cups with Polarine Transmission Cup 
Grease. It is acid-free and all lubricant. 
For satisfactory tractor service and economy of ope¬ 
ration buy your oils, greases and fuel under the 
So-CO-ny Sign.
