{WARNING:
Do not keep driving if the oil pressure is low.
The engine can become so hot that it catches fire.
Someone could be burned. Check the oil as soon
as possible and have the vehicle serviced.
Notice: Lack of proper engine oil maintenance
can damage the engine. The repairs would not be
covered by the vehicle warranty. Always follow the
maintenance schedule in this manual for changing
engine oil.
The engine oil pressure gauge shows the engine
oil pressure in psi (pounds per square inch) or
kPa (kilopascals) when the engine is running.
Oil pressure should be 140 to 550 kPa (20 to 80 psi).
In certain situations such as long, extended idles on
hot days, it could read as low as 40 kPa (6 psi) and still
be considered normal. It may vary with engine speed,
outside temperature and oil viscosity, but readings
above the shaded area show the normal operating
range. Readings in the shaded area tell you that the
engine is low on oil, or that you might have some
other oil problem. See Engine Oil on page 6‑19.

2. Once the oil has been drained from the engine, remove the engine oil filter and allow the oil to
drain.
3. Re‐install both drain plugs and tighten them to 25 Y (18 lb ft).
4. Replace the oil filter and tighten it to 30 Y
(22 lb ft). See Maintenance Replacement Parts
on
page 7‑12for the correct filter.
5. Oil is filled through the opening in the top of the external engine oil tank. Remove the oil fill cap.
6. Add 9.9 L (10.5 quarts) of oil to the oil tank. See Capacities and Specifications on page 6‑108.
7. Install the oil fill cap and insert the dipstick, if removed.
8. Start the engine and let it run at idle for at least 15 seconds. This will circulate the fresh engine oil
through the lubrication system.
9. Shut off the engine and check the oil level as described under “Checking Engine Oil (ZO6, ZR1,
and Grand Sport).”
What Kind of Engine Oil to Use
Look for three things:
.GM4718M
This vehicle's engine requires a special oil
meeting GM Standard GM4718M. Oils meeting
this standard may be identified as synthetic.
However, not all synthetic oils will meet this
GM standard. Use only an oil that meets GM
Standard GM4718M.
Notice: Using oils that do not have the GM4718M
Standard designation can cause engine damage not
covered by the vehicle warranty.
.SAE 5W-30
SAE 5W-30 is best for the vehicle. These numbers
on an oil container show its viscosity, or thickness.
Do not use other viscosity oils such as
SAE 20W-50.
.American Petroleum Institute (API) starburst
symbol

Engine Oil The engine requires a special engine
oil meeting GM Standard GM4718M.
Oils meeting this standard can be
identified as synthetic, and should
also be identified with the American
Petroleum Institute (API) Certified for
Gasoline Engines starburst symbol.
However, not all synthetic API oils
with the starburst symbol will meet
this GM standard. Look for and use
only an oil that meets GM Standard
GM4718M. For the proper viscosity,
