228 Driving and Operating
Fuels in Foreign Countries
The U.S., Canada, and Mexico post fuel
octane ratings in anti-knock index (AKI). For
fuel not to use in a foreign country, see
Prohibited Fuels0227.
Fuel Additives
TOP TIER Detergent Gasoline is highly
recommended for use with your vehicle.
If your country does not have TOP TIER
Detergent Gasoline, add ACDelco Fuel
System Treatment Plus−Gasoline to the
vehicle’s gasoline fuel tank at every oil
change or 15 000 km (9,000 mi), whichever
occurs first. TOP TIER Detergent Gasoline and
ACDelco Fuel System Treatment Plus
−Gasoline will help keep your vehicle’s
engine fuel deposit free and performing
optimally.
Filling the Tank
An arrow on the fuel gauge indicates which
side of the vehicle the fuel door is on. See
Fuel Gauge 086.
{Warning
Fuel vapors and fuel fires burn violently
and can cause injury or death.
Follow these guidelines to help avoid
injuries to you and others:
.Read and follow all the instructions on
the fuel pump island.
.Turn off the engine when refueling.
.Keep sparks, flames, and smoking
materials away from fuel.
.Do not leave the fuel pump
unattended.
.Avoid using electronic devices while
refueling.
.Do not re-enter the vehicle while
pumping fuel.
.Keep children away from the fuel
pump and never let children
pump fuel.
.Before touching the fill nozzle, touch a
metallic object to discharge static
electricity from your body.
(Continued)
Warning (Continued)
.Fuel can spray out if the fill nozzle is
inserted too quickly. This spray can
happen if the tank is nearly full, and is
more likely in hot weather. Insert the
fill nozzle slowly and wait for any hiss
noise to stop before beginning to
flow fuel.
The fuel door unlocks when the vehicle
doors are unlocked. See Remote Key
Operation 07.
To open the fuel door, push and release the
rearward center edge of the door.

Vehicle Care 251
1. Engine Oil Drain Plug
2. O-ring Seal
3. Engine Oil Filter
To change the engine oil and filter:1. Run the engine at idle for about 20 seconds to return all of the oil back
into the dry sump oil tank.
2. Turn the engine off prior to draining the oil.
3. Remove the engine oil drain plug from the bottom of the engine oil pan. Drain
plug removal will let the oil drain from
the external oil tank and residual oil
from the crankcase sump. Allow the oil
to drain. 4. Remove the engine oil filter and allow
the oil to drain.
5. Inspect the drain plug O-ring seal and replace if it is damaged. Reinstall the
drain plug into the oil pan and tighten it
to 25 N.m (18 lb ft).
6. Replace the oil filter and tighten it three-quarters to one turn after the
gasket makes contact. See Maintenance
Replacement Parts 0321 for the correct
filter.
7. Remove the oil fill cap from the external engine oil tank.
Add oil to the oil tank through the
opening in the fill tube. See Capacities
and Specifications 0325.
8. Install the oil fill cap and insert the dipstick, if removed.
{Warning
To help avoid personal injury and/or
engine damage, always install the engine
oil dipstick and oil fill cap until fully
seated to a stop. If not fully seated, oil
could escape on to hot exhaust parts and
cause a fire. 9. Start the engine and check the oil level
as described under "Checking the Engine
Oil." previously in this section.
Selecting the Right Engine Oil
Selecting the right engine oil depends on
both the proper oil specification and the
viscosity grade. See Recommended Fluids
and Lubricants 0320.
Specification
Use engine oils that meet the dexosR
specification.
Engine oils that have been approved by GM
as meeting the dexosR specification are
marked with the dexosR approved logo. See
www.gmdexos.com.
GM recommends Mobil 1 engine oils that
show the dexosR approved logo.
