Year Round Service 
No days lost from plowing or threshing — ample power for every job and 
no break-downs. That’s real year round service — the kind your.tractor 
will give if it gets the right care Much depends on correct lubrication. 
So-CO-ny 
Tractor Engine Oil 
is the oil the largest farm tractor manufacturers recommend. It will 
stand the extra high operating heat tractor engines develop—whether yy»a 
burn gasoline or kerosene. It will maintain full compression and provide 
an oil-cushion on valves, bearings, cylinders and pistons that defeats 
friction. Keeps tractors full powered the year round at least cost for 
overhauling and repairs. 
To Keep Your Tractor Engine Fit—long lived—operating efficiently and economically 
—keep So-CO-ny Gas Engine Tractor Oil in the crankcase.

Gear Oil. It will coat and cushion the surfaces and keep the gears operating quietly 
with the least possible wear. 
Where a cup grease is needed use Polarine Transmission Gup Grease. It is acid-free 
and all lubricant.
