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. Seals
Steps 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
4. Replace the oil filter and tighten
it to 30 (22 lb ft). See
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
.
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.

vehicle should have the dexos1
approved certification mark. This

oil has been approved to the dexos1
specification. Corvette recommends
