Ever wonder, why you
should change .the Spark _
plugs in,your ear after every
.10,000 Miles of driving?
There's a good reason. The
10,000 -mile plug change rec-
ommendation is not actually
based on the fact that spark
plugs are "worn out," in the
strictest sense, after .10,000
miles.

SaysTune-Up
Is Cure for
Air Pollution
They came to get ' a free
tune-up. They left with the
realization that a neglected
engine is a major contributor
---to the air pollution problem.
When engineering students
at the University .of Detroit
:detided to help observe En-
gineering Week by offering
free tune-ups to the public,
the students_did not antici-
pate the response. ' 04
Seeking to dramatize the
effects of undermaintenance
on harmful emissions,. the
students found 150 cars wait-
ing in, line at a campus facil-
ity. 'It was more than they
could handle so they invited .

the second week's - clinics
were exhausted in 15 minutes
s the public phoned ,in for
pointments.
What was the result of the
Clinic's study? ,
After tune-up, the averhge
hydrocarbon. emissions Were
reduced 52 percent.
And the average carbon
monoxide emissions were re-
duced 58 percent.
According to -clinic organ-
izers Bob Kaczorowski and
John Smreker, "The goals
that were set for the tune-up
were 400 parts per million of
hydrodarbons and 2.0% car-
bon monoxide. The average
HC reading coming in was
644 PPM, The, average CO
count was 3.06 percent.
