Recommended Oil
Oil container labels provide important
information.
The quality designation SG, SH, SJ,
SL,

or ILSAC
must be on the label.
Engine oil viscosity, or thickness, has an
effect on fuel economy and cold-weather
operation (starting and oil flow).
Low-viscosity engine oils can provide
improved fuel economy and cold-weather
performance.
But high-temperature weather conditions
require higher-viscosity engine oils for
satisfactory lubrication. When choosing an oil, consider the
temperature range your vehicle will
operate in before the next oil change.
Then select the recommended viscosity
from this chart.
Energy conserving oils are recommended.
A chief contribution they make to fuel
economy is reducing the amount of fuel
necessary to overcome engine friction.


Inspecting Engine Oil Level
1. Be sure the vehicle is on a level
surface.
2. Warm up the engine to normal operating temperature.
3. Turn it off and wait 5 minutes for the oil to return to the oil pan.
4. Pull out the dipstick, wipe it clean, and reinsert it fully.

recommended for specific temperature
ranges could result in engine damage.

5. Pull it out again and examine the level.It’s OK between L and F.
But if it ’s near or below L, add enough
oil to bring the level to F.
6. Make sure the O-ring is positioned properly before reinserting the
dipstick.
The distance between L and F on the
dipstick represents the following:

Changing Engine Oil and Filter
Change engine oil and filter according to
Scheduled Maintenance (page 8-3).
Please act responsibly
—protect the
environment and take used oil to a
recycling facility. Ask your dealer or a
service station for information. Changing engine oil
1. Warm up the engine for a few minutes
and turn it off. Remove the oil-filler
cap.
2. Remove the drain plug and drain the oil into a suitable container.
3. Replace the plug tightly after the oil has thoroughly drained.
4. Fill the engine with new oil to the F mark on the dipstick.
5. Securely replace the oil-filler cap.
6. Start the engine and inspect around the drain plug for leaks.
7. Turn it off and wait 5 minutes for the oil to return to the oil pan.
Don
’t add engine oil over F. This may
cause engine damage.
L (US qt, Imp qt) 0.8 (0.85, 0.70)
Handling Used Engine Oil:
Continuous contact with used engine
oil is dangerous. It could cause skin
cancer. Always wash with soap and
water immediately after changing oil
and filter.
CAUTION
WARNING
Checking or Changing Engine Oil:
Hot engine oil is dangerous. If the
engine has been running, the engine
oil becomes very hot. You could be
seriously burned. Don ’t check or
change the engine oil when the
engine is hot.

Check the oil level and fill to the F mark if
necessary.
Oil capacity (General reference only,
refer to Specifications section for
capacities.)
Changing oil filter
Because you need a special tool to
retighten the filter, an Authorized Mazda
Dealer should do the work.

Inspecting Coolant Level
Inspect the antifreeze protection and
coolant level in the coolant reservoir at
least once a year
—at the beginning of the
winter season —and before traveling
where temperatures may drop below
freezing.
Inspect the condition and connections of
all cooling system and heater hoses.
Replace any that are swollen or
deteriorated.
The coolant should be at full in the
radiator and between the FULL and LOW
marks on the coolant reservoir when the
engine is cool.
NOTE
• The indicated engine oil capacities
are for general reference purposes
only. When adding or changing oil,
verify the engine oil level with the
oil dipstick.
• Use only specified engine oil (page
10-4).
Engine Coolant
Hot Engine:
A hot engine is dangerous. If the
engine has been running, parts of the
engine compartment can become very
hot. You could be burned. Don
’t
inspect the coolant system or add
coolant when the engine is hot.

Inspecting Power Steering Fluid
Level
Inspect the fluid level at each engine oil
change. Add fluid if necessary; it does not
require periodic changing.
The level must be kept between the H and
L marks.
Visually examine the lines and hoses for
leaks and damage.
1. Park on a level surface, well off the
right-of-way, and set the parking brake
firmly.
2. Turn off the engine and allow it to cool.
•
Clutch fluid will damage painted
surfaces. If clutch fluid does get on
a painted surface, wipe it off
immediately.
• Using nonspecified clutch fluids
(page 10-4) will damage the system.
Mixing different fluids will also
damage it.
If the clutch system frequently
requires new fluid, it should be
inspected. Consult an Authorized
Mazda Dealer immediately.
NOTE
Low clutch fluid level may signal a
fluid leak. If you find a low fluid level,
have the clutch inspected.
CAUTIONPower Steering Fluid
To avoid damage to the power steering
pump, don
’t operate the vehicle for
long periods when the power steering
fluid level is low.
NOTE
Use specified power steering fluid
(page 10-4).

All moving points of the body, such as
door and hood hinges and locks, should
be lubricated each time the engine oil is
changed. Use a nonfreezing lubricant on
locks during cold weather.
Make sure the engine hood’s secondary
latch keeps the hood from opening when
the primary latch is released. This air filter may be cleaned with
compressed air and reused, or replaced,
depending on its condition. Unless it is
very dirty, simply shake it to remove
foreign particles. Each time you inspect it,
wipe inside the air cleaner housing with a
damp cloth.


Replacing the Air Filter
1. Unfasten the clamps.
Body LubricationAir Filter
Don
’t drive without an air filter. This
could result in excessive engine wear.
NOTE
If the vehicle is operated in very dusty
or sandy areas, replace the filter more
often than recommended intervals.
