AT least 50% of all serious engine 
troubles are traceable to careless 
buying of lubricating oil. 
You can’t dodge this fact. 
There is a wide gulf between the 
average “pick-up” oil and Gargoyle 
Mobiloil. 
We suggest you ask for Gargoyle 
Mobiloil, being particular to specify 
the correct grade for your car. 
How the Right oil saves money 
Many farmers expect entirely too little 
from their lubrication. 
The grade of Gargoyle Mobiloil spec¬ 
ified for your car or tractor feeds ade¬ 
quately to every friction point. It pro¬ 
tects. It seals the piston rings against 
blow-by of fuel and power—it saves 
fuel. It cuts down operat¬ 
ing troubles. And you aB 
will be surprised at your w* ^ 
greater freedom from 
carbon. !■—I 1C 
Yes: Gargoyle Mobil- m m ^ 
oil costs a few cents more per gallon. 
It costs more to manufacture. But you 
will see the real economy of this few 
cents difference after you observe the 
operating results. 
Not a gasoline by-product 
Nine out of ten lubricating oils on the 
market are simply by-products in the 
manufacture of gasoline. 
Gargoyle Mobiloil is not a by-product. 
It is produced by lubrication special¬ 
ists who are recognized the world over 
as leaders in lubricating practice. 
Gargoyle Mobiloil is manufactured 
from crude oil chosen for its lubricating 
qualities—not for its gasoline content. 
Gargoyle Mobiloil is manufactured by 
processes designed to bring out the high¬ 
est lubricating value—not the greatest 
gallonage of gasoline.

Warning! 
Don’t be misled by some similar 
sounding name. Look on the con¬
