The Associated Oil Company presents a
revolutionary achievement in scientific lubrication-
-Cycol
Cycol is a creation a new and dif
ferent motor oil with greater lubri
cating value. Its chemical charac
teristics make it different from both
"Eastern" and "Western" oils.
Cycol is made possible by the new
Hexeon Process developed and used
exclusively by the Associated Oil
Company.
The Hexeon Process removes de
structive "sulpho" compounds found
in lubricating oils. Oils containing
"sulpho" compounds are broken
down rapidly by engine heat.
Breaking down lubricating oil im
pairs the effectiveness of the lubri
cating film between all moving
parts, causing piston ring leakage,
poor compression and loss of power.
The oil in the crank case thus be-:-comes
contaminated and its lubri
cating value is greatly reduced.
