sediment damages your engine 
W HEN your engine loses 
power, knocks, bucks, and 
overheats, nine times out oi 
ten it is sediment in the oil 
that is to blame. 
Just look at the long list of vital parts 
that will quickly show serious wear 
when sediment is present in any consid¬ 
erable amount. 
Ordinary oil cannot resist the intense 
heat of the engine—200° to 1000°F. It 
breaks down quickly. The resulting 
sediment crowds out the oil with true 
lubricating qualities from points where 
it is needed most. Moving metal sur¬ 
faces, which should always lie separated 
by a protecting film of lubricant, are 
thus thrown into direct contact. 
Why sediment causes wear 
A strong magnifying glass reveals 
millions of microscopic teeth covering 
the apparently srnooth surface of a bear¬ 
ing or other working part. ' 
When the cushioning oil film between 
! these surfaces is de¬ 
stroyed or excluded 
by sediment these 
tiny metal teeth 
grind together, thus 
causing friction and 
wear. 
When this hap¬ 
pens in aii}^ import¬ 
ant part of an en¬ 
gine, costly replace¬ 
ments soon become 
necessary. Damage 
due to sediment iii 
ordinary oil can 
never he repaired.

A. Ludlow Clayden, I’nvri- 
neerit}}; Editor of Automotive 
Industries, and one of the most 
prominent eujiineers in the 
automol)ile fiehi, says : 
“In the past, too little atten¬ 
tion has been paid to lubriea- 
tion. Oil needs to he chosen for 
an engine almost more care- 
fullg iha)i food for a child.’- 
P. M. Heidi, reeoKiiized au¬ 
thority on internal comhustion 
(‘iigines, and auflior of “Tlie 
ilasoline Automohile," de¬ 
clares : ■ 
'•The proper selection of oil 
for the lubrication of an auto¬ 
mobile engine is a verg'impor¬ 
tant matter. 'The grade of lub¬ 
ricant used affects not onig the 
efficieneg of the engine but 
also its life." 
Chas. A. Daryea, (^»nsulting 
engineer and a pioneer in au¬ 
tomohile construction, states : 
“Jtuging inferior oil is the 
poorest ceonomg a motorist 
can practiec. Inferior oils must 
be used in greater quantities 
and, even then, theg increase 
friction, loss of potrer, fuel 
consumption, heat and repair 
bills. 
“flood oil costs a little more 
per gallon, but far less per 
mile.’’ 
That is why you cannot afford to 
buy ordinary oil at any price.' The 
cost of using it is appalling, because 
of its injurious effects on your 
engine. 
How the problem was solved 
As a result of exhaustive research atid 
comprehensive piActical tests the formation 
of sediment in dangerous quantities has 
been successfully overcome. 
Today over a million motorists a\oid the 
sediment menace, with its accompanying 
troubles and repair expense, and keep their 
cars running like new, at reduced operating 
cost, by using Wedol—the lubricant tliat 
resists heat. 
1 low Veedol reduces sediment 86% is made 
plain by the two bottles, showing the famous 
Sediment Test, at the left of the page. 
The average motor oil acts like water in a 
kettle. When water is subjected to intense he^t 
it eva[)orates as-steam. Under the terrilic heat 
of the engine ordinary oil evaporates very rapidly 
through the oil-filler in the form of vapor. 
Veedol not only resists destruction by heat and 
the consequent formation of sediment, but also 
reduces loss by evaporation in your engine to a 
minimum. You will get from 25% to 50% more 
mileage per gallon with Veedol for this reason. 
When figured by miles of service, and not by 
cost per gallon, Veedol proves much more econ¬ 
omical than ordinary oils.
