ENGINE OIL AND FILTER CHANGE
Under normal operating conditions, the oi
l is to be changed every 7,500 miles
(12,000km) or 12 months, whichever occurs first.
Although the manufacturer recommends changing the f ilter at the first oil
change and then at every other oil c hange, (unless 12 months pass between
changes), The editors of this informat ion recommend changing the filter with
each service. It is a small price to pay for extra protection.
When driving conditions frequently include dusty or polluted areas, trailer
towing, idling for long periods of ti me, or low speed operation, or when
operating at temperatures below freezing or driving short distances (under 4
miles or 6.4km), change t he oil and filter more frequently. Under these
circumstances, oil has a greater chance of building up sludge and contaminants
which could damage your engine. If your v ehicle use fits into one or more of
these categories, (as it does for most vehicles), it is suggested that the oil and
filter be changed every 3, 000 miles (1361km) or 3 months, whichever comes
first.
The oil should be disposed of properly after it is drained from the vehicle. Store
the oil in a suitable container and take the container to an official oil recycling
station. Most gas stations or oil and lube facilities will take the used oil at little or
no expense to you.
Oil should always be changed after the engine has been running long enough to
bring it up to normal operating temperature. Hot oil will flow more easily and will
carry more contaminants than will cold oi l. The oil drain plug is located on the
bottom of the oil pan (bottom of the engi ne, underneath the car). The oil filter is
located on the left side of most engines covered by this information. To change
the oil and filter:
1. Run the engine until it reaches normal operating temperature.
2. Raise the front of the vehicle and s upport it safely using a suitable pair of
jackstands.
3. Slide a drain pan of a least 6 quar ts capacity under the oil pan. Wipe the
drain plug and surrounding area clean using an old rag.
CAUTION - The EPA warns that prolonged contact with used engine oil may
cause a number of skin disorders, incl uding cancer! You should make every
effort to minimize your exposure to used engine oil. Pr otective gloves should be
worn when changing the oil. Wash y our hands and any other exposed skin
areas as soon as possible after exposure to used engine oil. Soap and water, or
waterless hand cleaner should be used.
4. Loosen the drain plug using a ratc het, short extension and socket or a
box-wrench. Turn the plug out by hand, using a rag to shield your fingers
from the hot oil. By keeping an in ward pressure on the plug as you
unscrew it, oil won't escape past the threads and you can remove it
without being burned by hot oil.

10. Refill the engine with the correct amount
of fresh oil. Please refer to the
Capacities chart at the end of this section.
11. Check the oil level on the dipstick. It is normal for the level to be a bit
above the full mark. Start the engine and allow it to idle for a few
minutes.
CAUTION - Do not run the engi ne above idle speed until it has built up oil
pressure, as indicated w hen the oil light goes out
12. Shut off the engine and allow the oil to flow back to the crankcase for a
minute, then recheck the oil level. C heck around the filter and drain plug
for any leaks, and correct as necessary.
MANUAL TRANSMISSIONS
FLUID RECOMMENDATIONS
• 1982-85 4-speed manual transmissi ons - SAE 80W/90 GL-5 gear
lubricant
• 1986-87 4-speed manual transmission - Dexron®®II automatic
transmission fluid
• 1982-84 5-speed manual transmissions - use SAE 80W/90 GL-5 gear
lubricant (SAE 80W GL-5 in Canada)
• 1985-92 5-speed manual transmissi ons - Dexron®II automatic
transmission fluid
LEVEL CHECK
The oil in the manual tr ansmission should be check ed every 12 months or
15,000 miles.
1. Raise the car and support on jackstands as close to level as possible. \
2. Remove the filler plug from the side of the transmission housing.
3. If lubricant begins to trickle out of the hole, there is enough and you need
not go any further. Otherwise, carefully insert your finger (watch out for
sharp threads) and check to see if the oil is up to the edge of the hol\
e.
4. If not, add oil through the hole until the level is at the edge of the hole.
Most lubricants come in a plasti c squeeze bottle with a nozzle; making
additions simple.
5. Install and tighten the filler plug.
DRAIN AND REFILL
The fluid in the manual transmission do es not require changing. If you do
choose to change the transmission fluid, the fluid can be drained out through
the lower drain plug hole on the side of the transmission. Fill the transmission
with the recommended lubricant to the bottom of the filler plug hole and install
the filler plug.
