1993 BUICK SKYLARK oil filter

0 It’s below freezing outside and most trips are less
than
10 miles (16 km).
0 The engine is at low speed most of the time (as in
door-to-door delivery, or in stop-and-go traffic).
0 You tow a trailer often.
0 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.
Engine Block Heater: An engine block heater can be a
big help if you have to park outside in very cold weather, -20
F (-29 C) or colder. If your vehicle has
this option, see “Engine Block Heater.” in the Index.
What to Do with Used Oil:
I sed engine oil contains things that have caused
skin cancer in laboratory animals. Don’t let used
oil stay on your skin for very long. Clean your
skin and nails with soap and water,
or a good
hand cleaner. Wash
or properly throw away
c-othing
or rags containing used engine oil.
Used oil can be a real threat to the environment. Don’t
ever dispose of it by pouring it on the ground, into
sewers, or into streams or bodies of water. Instead,
recycle it by taking it to a place that collects used
oil. If
you have a problem propeily disposing of your used oil,
ask your dealer, a service station or a local recycling center for help.

I1 oils of proper viscosity. The
“SG, designation may be shown alone or in
combination with others, such as “SG/CC”,
“SG/CD” or “SF,
SG, CC,” etc. To determine the
preferred viscosity for your vehicle’s engine (e.g.,
SAE 5W-30 or SAE 10W-30), see “Engine Oil” in
the Index.

Inspect hoses and replace if they are cracked,
swollen or deteriorated. Tighten screw-type hose
clamps. Clean the outside of the~radiator and air
conditioning condenser. Wash the pressure cap and
neck.
To help ensure proper operation, we recommend a
pressure test
of both the cooling system and the
pressure cap.
7. Transaxle Service -- Change both the fluid and
filter every
15,000 miles (25 000 km) if the vehicle
is mainly driven under one or more of these
conditions:
0 In heavy city traffic where the outside
temperature regularly reaches
90 F (32 C) or
higher.
0 In hilly or mountainous terrain.
When doing frequent trailer towing. (With some
models, you shouldn’t ever tow a trailer. See
“Towing a Trailer” in the Index.)
Uses such as found in taxi, police car or delivery
