use SAE 1OW-30 if it's going to be 0°F
(-18°C) or above. These numbers on an
oil container show its viscosity, or
thickness. Do not use other viscosity oils,
such as SAE 1OW-40 or SAE 20W-50.
If you cannot find oils with the new
"starburst" symbol on the front of the
container, you should look for and use
oils containing the following three things:
SH or SG
"SH" or "SG" must be on the oil
container, either by itself or combined
with other quality designations, such
as "SWCD," "SH,SG,CD," "SG/CD," etc.
These letters show American Petroleum
Institute (API) levels of quality.
SAE 5W-30
Energy Conserving
I1
Oils with these words on the
container will help you save fuel.
These three things are usually included
in a doughnut shaped logo (symbol) on
most containers. If you cannot find oils
with the "starburst" symbol, you should
look for oils with the doughnut shaped
symbol, containing the three things
noted above.

When to Change Engine Oi/
See if any one of these is true for you:
Most trips are less than 4 miles (6
km).
It's below freezing outside and most
trips are less than 10 miles (16
km) .
The engine is at low speed most of the
time (as in door-to-door delivery, or in
stop-and-go traffic).
Most trips are through dusty places.
If any one of these is true for your
vehicle, then you need to change your
oil and filter every 3,000 miles (5
000
km) or
3
months - whichever comes
first.
If none of them is true, change the oil
every 7,500 miles
(12
500 km) or 12
months - whichever comes first.
Change the filter at the first oil change
and at every other oil change after that.
