I 'MLRY automobilist who wants to 
^ycut down repair bills should have

opening sen ten ce,“ ()r:c hal'cfevery dollar 
spent for automobile repairs is wasted!” 
Every year American motorists spend 
at least one hundred million dollars un¬ 
necessarily for engine repairs. 
Our Booklet, “Correct Lubrication,” 
diagnoses the cause of much of this 
immense national waste. It deals simply 
and scientifically with first causes. 
It discusses causes of repairs, engine 
factors, fl&rication factors, carbon forma¬ 
tion. It describes oil tests—where they 
are important where they mean nothing, 
orwprse than nothing. 1 f dealswith trans¬ 
mission and differential 
lubrication, explaining 
why lubrication practice 
of a few- years back is 
today obsolete—why 
old practice points to 
repair bills. 
points out the penalties which come from 
this dangerous practice. 
You may think that you have no avoid¬ 
able repairs. So do millions of other motor¬ 
ists! rind they are the very men who con¬ 
tribute to the hundred million dollar repair 
fund which represents sheer waste. 
Motorists need information on -this 
vital subject. This information is pro¬ 
vided for you in our Booklet, “Correct 
Lubrication.” The 1921 edition is now 
ready. It contains the tacts. I'hey are 
simply presented easy to get at, easy
