In addition, any new engine

New Removal Methods.
When carbon has reached the
stage where II Ia definitely cutting

can DO removed by the new and
simpler methods,

A Few Simple Rules,

bon can be held In check by some
ample rules, Use not only the
best brands OF lubrieating oils, but
the rleht grades % well, DO not
oyerhlll tho orAnkeaAe, Change
oil more often even II the engine
has On efioiOnt oil filter, Use
valve oils aa Addltives In with the
oil, preferably 90 miles before q
eood workout and q hot oil change.
Don't operate without 0 motor
thermostat and In cold weather
drive an extra mile or two 20 warm
up the engine before stopping,
Avoid unnecessary slow idlina,
Avoid sudden closing OF the thrOts
