Fuel E85 (85% Ethanol) The 8th digit of your Vehicle Identification Number (VIN) shows the code letter or number that identifies your engine. You will find the VIN at the top left of the instrument panel. See Vehicle Identification Number (VIN) on page 388. If your vehicle has the 5.3L V8 engine (VIN Code Z only), you may use either regular unleaded gasoline or ethanol fuel containing up to 85% ethanol (E85); also see Fuel on page 288. In all other engines, use only the unleaded gasoline described under Gasoline Octane on page 289. Only vehicles that have the 5.3L V8 engine (VIN Code Z) may use 85% ethanol fuel (E85). General Motors encourages the use of E85 in vehicles that are designed to use it. The ethanol in E85 is a "renewable" fuel, meaning it is made from renewable sources such as corn and other crops. Many service stations will not have an 85% ethanol fuel (E85) pump available. The U. S. Department of Energy has an alternative fuels website (www.eere.energy.gov/afdc/infrastructure/ locator.html) that can help you find E85 fuel. Those stations that do have E85 should have a label indicating ethanol content. Do not use the fuel if the ethanol content is greater than 85%. At a minimum, E85 should meet ASTM Specification D 5798. By definition, this means that fuel labeled E85 will have an ethanol content between 70% and 85%. Filling the fuel tank with fuel mixtures that do not meet ASTM specifications can affect driveability and could cause the check engine light to come on. To ensure quick starts in the wintertime, the E85 fuel must be formulated properly for your climate according to ASTM specification D 5798. If you have trouble starting on E85, it may be because your E85 fuel is not properly formulated for your climate. If this happens, switching to gasoline or adding gasoline to your fuel tank may improve starting. For good starting and heater efficiency below 32°F (0°C), the fuel mix in the fuel tank should contain no more than 70% ethanol. It is best not to alternate repeatedly between gasoline and E85. If you do switch fuels, it is recommended that you add as much fuel as possible - do not add less than three gallons (11 L) when refueling. You should drive the vehicle immediately after refueling for at least seven miles (11 km) to allow the vehicle to adapt to the change in ethanol concentration. 291

Fuel E85 (85% Ethanol)

The 8th digit of your Vehicle Identiﬁcation

Number (VIN) shows the code letter or number

that identiﬁes your engine. You will ﬁnd the VIN at

the top left of the instrument panel. See

Vehicle

Identiﬁcation Number (VIN) on page 388

If your vehicle has the 5.3L V8 engine (VIN Code Z

only), you may use either regular unleaded gasoline

or ethanol fuel containing up to 85% ethanol (E85);

also see

Fuel on page 288

. In all other engines,

use only the unleaded gasoline described under

Gasoline Octane on page 289

Only vehicles that have the 5.3L V8 engine (VIN

Code Z) may use 85% ethanol fuel (E85). General

Motors encourages the use of E85 in vehicles that

are designed to use it. The ethanol in E85 is a

“renewable” fuel, meaning it is made from

renewable sources such as corn and other crops.

Many service stations will not have an 85% ethanol

fuel (E85) pump available. The U. S. Department

of Energy has an alternative fuels website

(www.eere.energy.gov/afdc/infrastructure/

locator.html) that can help you ﬁnd E85 fuel.

Those stations that do have E85 should have a

label indicating ethanol content. Do not use the

fuel if the ethanol content is greater than 85%.

At a minimum, E85 should meet ASTM

Speciﬁcation D 5798. By deﬁnition, this means

that fuel labeled E85 will have an ethanol content

between 70% and 85%. Filling the fuel tank

with fuel mixtures that do not meet ASTM

speciﬁcations can affect driveability and could

cause the check engine light to come on.

To ensure quick starts in the wintertime, the

E85 fuel must be formulated properly for your

climate according to ASTM speciﬁcation D 5798.

If you have trouble starting on E85, it may be

because your E85 fuel is not properly formulated

for your climate. If this happens, switching to

gasoline or adding gasoline to your fuel tank may

improve starting. For good starting and heater

efficiency below 32°F (0°C), the fuel mix in the fuel

tank should contain no more than 70% ethanol.

It is best not to alternate repeatedly between

gasoline and E85. If you do switch fuels, it

is recommended that you add as much fuel as

possible — do not add less than three gallons

(11 L) when refueling. You should drive the vehicle

immediately after refueling for at least seven

miles (11 km) to allow the vehicle to adapt to the

change in ethanol concentration.
