Choosing the Right
_
Q
uality-
Oil (Diesei Engines)
Engfne
oils are
labeled
on
the
containers
with
various
API
(American
Petroleum
Institute) designations
·of
q~ality.
Use
an oil
labeled,
with both
designations SF
and CD; or, with both
designations SF
and
CC.
Using any quality oils other
than those recommended could cause engine damage. For
example,
do
not use
oils
labeled ONLY SA,
$B,
SC, SD,
SE,
CA,
CB,
ce,
or CD;
or oils
with a combination of anX
of
these
letters·
such
as.
"SErCD."
Choosing Oil Viscosity (Diesel Engines)
Engine
oil viscosity (thickness)
has
an
effect
on
tuel
economy.
Lower viscosity
engine
oils can prol'ide
better
fuel-
economy;
however,
higher
temperature
weather
conditions
require higher
viscbsity engine oils for satisfactory
.
lubrication.
Using oils of any
viscosity
other than
those
viscosities
recommended could cause
engine-damage._
When>chQosing an
