Philosophy 
Should old cars use heavier oil? 
I N CHINA when roads get muddy 
the drivers put heavier wheels on 
their carts. The road is left to grow 
worse and worse. 
In America when automobile engines 
begin to wear out, some motorists think 
it is time to change to heavier oil. The 
engine is left—to grow worse and worse. 
For a time, heavier oil may partially 
restore compression and power. BUI' it 
may not distribute to the bearings. BUT 
it.may choke your combustion chambers 
with sticky carbon deposit. BUT some 
fine day your heavier oil may bring your 
car to a sharp stop for expensive repairs. 
Then you are in trouble. 
Age does not alter the delivering ca¬ 
pacity of your oil pump. It was designed 
specifically to distribute oil of a certain 
body —and none heavier. Your 
oil feeds don't grow larger as 
your engine grows older. 
They may not accommodate 
the “heavier” oil. At best. 
“heavier oil” acts only as a 
temporary stop-gap. At worst 
it starts new and far more serious troubles. 
No. Stick to the Chart on the right. 
Worn engines need repairs or renewals of 
parts. That is the only way to retain as 
long as possible the original engine efficiency 
of your car . 
When used as specified in the Chart, 
Gargoyle Mobiloils give scientific .lubri¬ 
cation. These oils prove their economy 
through providing greater lubrication; 
which means longer life, less renewal of 
parts, greater mileage per gallon of gaso¬ 
line, greater mileage per gallon of oil, full 
compression and the greatest possible 
freedom from carbon troubles. 
If your car is not listed in the partial chart 
shown here, consult the Chart of Recom¬ 
mendations at your dealer’s, 
or send for booklet, “Correct 
Lubrication,” which lists the 
correct grades for all automo¬ 
biles, tractorsand motorcycles.

Chart of 
Recommendations 
(Abbreviated Edition) 
How to Read the Chart: 
T HE correct grades of Gargoyle Mobiloils for 
engine lubrication of both passenger and com¬ 
mercial cars are specified in the Chart below: 
A means Gargoyle Mobiloil “A’* 
B. means Gargoyle Mobiloil “B” 
E means Gargoyle Mobiloil “E” 
Arc means Gargoyle Mobiloil Arctic 
Where different grades are recommended for summer 
and winter use, the winter recommendations should' 
be followed during the entire period when freezing 
temperatures may be experienced. 
The recommendations for prominent makes of engines 
used in many cars are listed separately for convenience. 
The Chart of Recommendations is compiled by the 
Vacuum Oil Company’s Board of Automotive 
Engineers, and represents our professional advice on I 
correct automobile lubrication.
