Don’t let “looks” 
rob your pocket-book 
You can’t choose oil 
or Black Valentine beans by “looks” alone 
T HESE bean seeds certainly look alike. 
They even come from the same fam¬ 
ily—Black Valentine. But one pile will 
grow fancy stringless beans which earn a 
good profit. 
The other variety will grow just plain, 
stringy beans. It isn’t safe to judge by 
appearances! 
It costs even more to pick oil on looks 
alone. The poorest may look like the fin¬ 
est, and it is impossible to tell from 
appearance whether or not an oil is the 
right one for your motor. The eye can’t 
detect the difference. But your motor 
can, and though it may not immediately 
complain, a poorer crop of power and a 
bigger crop of wear are as sure as to¬ 
morrow’s sunrise. 
Talk with any man, v/ho doesn’t judge 
by appearances, who buys certified seed 
and pure-bred cattle, and you’ll find a 
man who uses good judgment in his treat¬ 
ment of automotive equipment. He will 
tell you that the cheapest oil may pro¬ 
vide the most expensive lu¬ 
brication, and that one un¬ 
necessary breakdown, one 
repair bill for prematurely- 
worn parts, will quickly 
wipe out any fancied saving. 
A man of this type is very likely to use 
Mobiloil, because: 
1 He refuses to be fooled by appearances. 
2 He knows that no other company has 
specialized in lubrication as has 
the Vacuum Oil Company. 
3 His judgment in selecting Mobiloil is 
backed by the approval of practi¬ 
cally every manufacturer of auto¬ 
mobiles, motor trucks, and farm 
tractors. 
4 He is sure of getting the correct oil for 
each individual car, truck, tractor, 
or farm lighting unit. 
5 He has proved that Mobiloil is the 
most economical oil to use.

Gargoyle Mobiloil is not a gasoline by¬ 
product. It is refined from crude stocks 
chosen solely for lubricating qualities. 
The Vacuum Oil Company has special¬ 
ized exclusively in lubricating oils for 
over 58 years, and its recommendations 
are accepted as scientifically correct by 
engineers all over the world. Make the 
Chart of Recommendations your guide. 
You will obtain economical 
results from this certified oil 
just as truly as you obtain 
profit from the certified seed 
which comes from your ex¬ 
periment station.
