Fuel E85 (85% Ethanol)

The 8th digit of the Vehicle Identiﬁcation Number (VIN)

shows the code letter or number that identiﬁes your

vehicle’s engine. The VIN is at the top left of the

instrument panel. See Vehicle Identiﬁcation Number

(VIN) on page 5-105.

If your vehicle has the 5.3L V8 engine (Code 0) or the

5.3L V8 engine (Code 3), you can use either regular

unleaded gasoline or ethanol fuel containing up to

85% ethanol (E85); also see Fuel on page 5-5.Inall

other engines, use only the unleaded gasoline described

under Gasoline Octane on page 5-6.

Only vehicles that have the 5.3L V8 engine (Code 0)

or the 5.3L V8 engine (Code 3) can use 85% ethanol

fuel (E85). We encourage 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 malfunction indicator

lamp 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 could be because the E85 fuel is not

properly formulated for your climate. If this happens,

switching to gasoline or adding gasoline to the fuel tank

can 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.
