Engine Oil
To ensure proper engine
performance and long life, careful
attention must be paid to engine oil.
Following these simple, but
important steps will help protect
your investment:
.Always use engine oil approved
to the proper specification and of
the proper viscosity grade. See
“Selecting the Right Engine Oil”
in this section.
.Check the engine oil level
regularly and maintain the
proper oil level. See “Checking
Engine Oil” and“When to Add
Engine Oil” in this section.
.Change the engine oil at the
appropriate time. See Engine Oil
Life System on page 10-16.
.Always dispose of engine oil
properly. See “What to Do with
Used Oil” in this section.
Checking Engine Oil
(Except Z51)
If the ENGINE OIL LOW–ADD OIL
message displays on the Driver
Information Center (DIC), check the
engine oil level right away. See
Engine Oil Messages on page 5-35.
Check the engine oil level regularly.
It is a good idea to check the engine
oil level at each fuel fill. In order to
get an accurate reading, the vehicle
must be on level ground. The
engine oil dipstick handle is a loop.
SeeEngine Compartment Overview
on page 10-7 for the location of the
engine oil dipstick.

10-14 Vehicle Care
Changing Engine Oil and
Filter (Z51)
The vehicle may have a
racetrack-ready dry sump engine
lubrication system. This high
performance system operates
differently than a standard engine
lubrication system and requires a
special procedure when changing
the engine oil and filter. Follow this
procedure closely when changing
the engine oil and filter.
1. Engine Oil Drain Plugs
2. SealsSteps to follow:
1. Remove the two engine oil drain
plugs from the bottom of the
engine oil pan. One drain plug
drains the external oil tank via
the oil transfer supply line. The
other drain plug drains residual
oil from the crankcase sump.
Allow the oil to drain.
2. Once the oil has been drained from the engine, remove the
engine oil filter and allow the oil
to drain.
3. Reinstall 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 11-14 for 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 oil to the oil tank. See Capacities and Specifications on
page 12-2. 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 (Z51).”
Selecting the Right Engine Oil
Selecting the right engine oil
depends on both the proper oil
specification and viscosity grade.
See Recommended Fluids and
Lubricants on page 11-12.
Specification
Use and ask for licensed engine oils
with the dexos1
®approved
certification mark. Engine oils
meeting the requirements for the
vehicle should have the dexos1
approved certification mark. This
certification mark indicates that the
oil has been approved to the
dexos1 specification. See
www.gmdexos.com.

6007198) - 2014 - CRC - 2/5/14
Vehicle Care 10-15
Corvette recommends Mobil 1®
engine oils that meet the
requirements of the dexos1
specification for its dry sump
equipped engines.
{Caution
Failure to use the recommended
engine oil can result in engine
damage not covered by the
vehicle warranty. Check with your
dealer or service provider on
whether the oil is approved to the
dexos1 specification.Viscosity Grade
Use SAE 5W-30 viscosity grade
engine oil.
Cold Temperature Operation: In an
area of extreme cold, where the
temperature falls below
−29°C
(−20°F), an SAE 0W-30 oil may be
used. An oil of this viscosity grade
will provide easier cold starting for
the engine at extremely low
temperatures. When selecting an oil
of the appropriate viscosity grade,
always select an oil of the correct
specification. See “Specification”
earlier in this section for more
information.
For track events or competitive
driving, use Mobil 1
®15W-50
engine oil. An instrument cluster
warning light will be illuminated at
high oil temperatures. See Driver
Information Center (DIC) on
page 5-24.
Engine Oil Additives/Engine
Oil Flushes
Do not add anything to the oil. The
recommended oils with the dexos
specification and displaying the
dexos certification mark are all that
is needed for good performance and
engine protection.
Engine oil system flushes are not
recommended and could cause
engine damage not covered by the
vehicle warranty.
What to Do with Used Oil
Used engine oil contains certain
elements that can be unhealthy for
your skin and could even cause
cancer. Do not 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 dispose of clothing or rags
containing used engine oil. See the
manufacturer's warnings about the
use and disposal of oil products.
