Chevrolet Silverado: Fuel / E85 or FlexFuel

Chevrolet Silverado 2019-2024 Owners Manual / Driving and Operating / Fuel / E85 or FlexFuel

Vehicles with a yellow fuel sticker on the fuel door can use either unleaded gasoline or fuel containing up to 85% ethanol (E85). All other vehicles should use only the unleaded gasoline as described in Recommended Fuel (Except 6.2L V8 Engine) 0 276 or Recommended Fuel (6.2L V8 Engine).

The use of E85 or FlexFuel is encouraged when the vehicle is designed to use it. E85 or FlexFuel is made from renewable sources.

To help locate fuel stations that carry E85 or FlexFuel, the U.S. Department of Energy has an alternative fuel website. See www.afdc.energy.gov/afdc/locator/stations.

E85 or FlexFuel should meet ASTM Specification D 5798 or CAN/CGSB–3.512 in Canada. Do not use the fuel if the ethanol content is greater than 85%. Fuel mixtures that do not meet ASTM or CGSB specifications can affect driveability and could cause the malfunction indicator lamp to come on.

The starting characteristics of E85 or FlexFuel make it unsuitable for use when temperatures fall below −18 °C (0 °F). Use gasoline or add gasoline to the E85 or FlexFuel.

Because E85 or FlexFuel has less energy per liter (gallon) than gasoline, the vehicle will need to be refilled more often. See Filling the Tank (Pickup Model) or Filling the Tank (Chassis Cab Model).

The only GM approved aftermarket additive is ACDelco Fuel System Treatment Plus-FlexFuel. Follow the instructions on the bottle for proper use. This product is available at your GM dealer.

Caution

Some additives are not compatible with E85 or FlexFuel and can harm the vehicle's fuel system. Use only additives approved by GM for E85 or FlexFuel vehicles. Damage caused by unapproved additives would not be covered by the vehicle warranty.

Caution

Do not use fuel containing methanol. It can corrode metal parts in the fuel system and also damage plastic and rubber parts. That damage would not be covered under the vehicle warranty.

To help keep the engine running efficiently, fill the tank with gasoline, up to E15, after filling the tank with E85 one or two times.

    Prohibited Fuels

    Caution Do not use fuels with any of the following conditions; doing so may damage the vehicle and void its warranty: For vehicles that are not FlexFuel, fuel labeled greater than 15% ethanol by volume, such as mid-level ethanol blends (16–50% ethanol), E85, or FlexFuel...

    Blind Spot Mirrors

    If equipped, there is a small convex mirror built into the upper and outer corner of the driver outside mirror. It can show objects that may be in the vehicle's blind zone.

    Driving with the Blind Spot Mirror

    Actual Mirror View

    When the approaching vehicle is a long distance away, the image in the main mirror is small and near the inboard edge of the mirror. As the vehicle gets closer, the image in the main mirror gets larger and moves outboard. As the vehicle enters the blind zone, the image transitions from the main mirror to the blind spot mirror. When the vehicle is in the blind zone, the image only appears in the blind spot mirror.
