How  about 
“Give  me  [ 
LIGHT 
MEDIUM 
HEAVY 
]  Oil” 
Dangerous  word  juggling. 
And  why. 
m 
Many  Oil  Users  think  they  are  safe  in 
asking  merely  for  “light,”  “medium,” 
or  “heavy”  oil.  If  you  feel  that  way  too,  here 
are  some  facts  which  will  interest  you: 
One  well-known  “heavy”  oil  has  the  same 
body  at  I50°F  (average  crank-case  tempera¬ 
ture)  as  another  well-known  “light”  oil.  Two 
well-known  “light”  oils  are  equally  far  apart 
in  body.  Among  oils  classified  as  “light,” 
-  “medium,”  and  “heavy”  there  exists  a  wide 
variation.  There  are  no  accepted  standards  for 
light,  medium  and  heavy  oils. 
In  asking  for  “light  oil”  you  run  the  risk  of 
getting  “light”  oil  today,  “medium”  oil  next 
week,  and  “heavy”  oil  before  the  month  is  out. 
That  is  why  more  farmers  than  ever  before 
are  following  the  Chart  and  buying  only  Gar¬ 
goyle  Mobiloil  for  their  automobiles,  motor 
trucks,  tractors  and  farm  lighting  equipment. 
There’s  always  a  dealer  nearby  who  has  the 
several  grades  of  Gargoyle  Mobiloil  and  the 
Chart  of  Recommendations.  He  can  tell  you 
the  correct  grade  or  grades  for  your  automo¬ 
bile  and  other  equipment. 
Farmers  find  the  15 — 30 — and  55  gallon 
steel  drums  ideal  for  their  use.  Next  time  you 
are  in  town  see  how  durable  and  convenient 
they  are. 
Not  a  By-product 
Unlike  9  out  of  10  oils  offered  you,  Gargoyle 
Mobiloil  is  produced  from  crude  stocks  chosen 
primarily  for  their  lubricating  value — not  for 
gasoline  yield.  This  distinct  specialization  in 
lubricating  oils  has  won  for  the  Vacuum  Oil 
Company  it^  world-wide  recognition  as  the 
outstanding  authority  on  correct  lubrication. 
You  will  never  get  Gargoyle  Mobiloil  econ¬ 
omy  until  you  use  Gargoyle  Mobiloil.  Tou 
cannot  expect  full  Gargoyle  Mobiloil  results 
until  you  make  the  Chart  your  guide.

Address  our 
nearest  branch: 
Fair  Retail  Price— 30c  a  Quart 
When  the  dealer  sells  a  quart  of  Gargoyle 
Mobiloil  for  less  than  30c,  he  does  not  make 
his  fair,  reasonable  profit. 
Lower  prices  often  accompany  substitution 
of  low-quality  oil  for  genuine  Gargoyle 
Mobiloil. 
Prices  are  slightly  higher  in  Canada,  the 
Southwest,  and  the  Far  West. 
TRACTOR  LUBRICATION : 
The  correct  engine  lubricant  for  the  FORDSON* 
TRACTOR  is  Gargoyle  Mobiloil  "BB”  in  sum¬ 
mer  and  Gargoyle  Mobiloil  “A”  in  winter.  The 
correct  oil  for  all  #ther  tractors  is  specified  in  our 
Chart.  Ask  for  it  at  vour  dealer’s.

Chart  of 
Recommendations 
(Abbreviated  Edition) 
THE  correct  grades  of  Gargoyle  Mobiloil  for 
engine  lubrication  of  both  passenger  and  com¬ 
mercial  cars  are  specified  in  the  Chart  below. 
A  means  Gargoyle  Mobiloil  “A” 
How  to  B  means  Gargoyle  Mobiloil  “B” 
Read  the  BB  means  Gargoyle  Mobiloil  “BB” 
Chart:  E  means  Gargoyle  Mobiloil  “E” 
Arc  means  Gargoyle  Mobiloil  Arctic 
Where  different  grades  are  recommended  for  summer 
and  winter  use,  the  winter  recommendation  shpuld 
be  followed  during  the  entire  period  when  freezing 
temperatures  may  be  experienced. 
This  Chart  of  Recommendations  is  compiled  by  the 
Vacuum  Oil  Company’s  Board  of  Automotive 
Engineers,  and  represents  our  professional  advice  on 
correct  automobile  lubrication.
