2022 Chevrolet Silverado 1500 Fuel Guide

Fuel

Top Tier Fuel

GM recommends the use of TOP TIER Detergent Gasoline to keep the engine clean, reduce engine deposits, and maintain optimal vehicle performance. Look for the TOP TIER Logo or see www.toptiergas.com for a list of TOP TIER Detergent Gasoline marketers and applicable countries.

Recommended Fuel (2.7L L4 and 5.3L V8 Engines)

For diesel engine vehicles, see “Fuel for Diesel Engines” in the Duramax diesel supplement.

• Regular unleaded gasoline meeting ASTM specification D4814 with a posted octane rating (R+M)/2 of 87 or greater is recommended. Do not use gasoline with a posted octane rating of less than 87, as this will result in reduced performance and driveability. If heavy knocking is heard when using gasoline rated at 87 or greater, the engine needs service.
• Do not use any fuel labeled E85 or FlexFuel.
• Do not use gasoline with ethanol levels greater than 15% by volume.

Recommended Fuel (6.2L V8 Engine)

• Premium unleaded gasoline meeting ASTM specification D4814 with a posted octane rating (R+M)/2 of 91 or greater is recommended. If unavailable, unleaded gasoline with a posted octane rating of 87 may be used, but will result in reduced performance and driveability. If heavy knocking is heard when using gasoline rated at 91 or greater, the engine needs service.
• Do not use any fuel labeled E85 or FlexFuel.
• Do not use gasoline with ethanol levels greater than 15% by volume.

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 volumes, such as mid-level ethanol blends (16–50% ethanol), E85, or FlexFuel.
• Fuel with any amount of methanol, methylal, ferrocene, and aniline. These fuels can corrode metal fuel system parts or damage plastic and rubber parts.
• Fuel containing metals such as methylcyclopentadienyl manganese tricarbonyl (MMT), can damage the emissions control system and spark plugs.
• Fuel with a posted octane rating of less than the recommended fuel. Using this fuel will lower fuel economy and performance, and may decrease the life of the emissions catalyst.

Fuels in Foreign Countries

The U.S., Canada, and Mexico post fuel octane ratings in the anti-knock index (AKI). For fuel not to use in a foreign country, see Prohibited Fuels 0 301.

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 (Pickup Model)

If the vehicle has a diesel engine, see the Duramax diesel supplement. An arrow on the fuel gauge indicates which side of the vehicle the fuel door is on. See Fuel Gauge 108.

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.
• 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 capless refueling system does not have a fuel cap. Fully insert and latch the fill nozzle, begin fueling.

Warning

Overfilling the fuel tank by more than three clicks of a standard fill nozzle may cause:

• Vehicle performance issues, including engine stalling and damage to the fuel system.
• Fuel spills.
• Under certain conditions, fuel fires.

Be careful not to spill fuel. Wait five seconds after you have finished pumping before removing the fill nozzle. Clean fuel from painted surfaces as soon as possible. See Exterior Care 0 411. Push the fuel door closed.

Warning

If a fire starts while you are refueling, do not remove the fill nozzle. Shut off the flow of fuel by shutting off the pump or by notifying the station attendant. Leave the area immediately

Filling the Tank with a Portable Fuel Container

If the vehicle runs out of fuel and must be filled from a portable fuel container:

• Locate the capless funnel adapter.
• Insert and latch the funnel into the capless fuel system.
  Warning Attempting to refuel from a portable fuel container without using the funnel adapter may cause fuel spillage and damage the capless fuel system. This could cause a fire. You or others could be badly burned and the vehicle could be damaged.
• Remove and clean the funnel adapter and return it to the storage location.

Filling the Tank (Chassis Cab Model)

An arrow on the fuel gauge indicates which side of the vehicle the fuel door is on. See Fuel Gauge 0 108.

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.
• Fuel can spray out if the fuel cap is opened too quickly. This spray can happen if the tank is nearly full, and is more likely in hot weather. Open the fuel cap slowly and wait for any hiss noise to stop, then unscrew the cap all the way.

Use the fuel cap key to unlock the fuel cap then turn the fuel cap counterclockwise to remove it. Fully insert and latch the fill nozzle, and begin fueling.

Warning

Overfilling the fuel tank by more than three clicks of a standard fill nozzle may cause:

• Vehicle performance issues, including engine stalling and damage to the fuel system.
• Fuel spills.
• Under certain conditions, fuel fires.

Be careful not to spill fuel. Wait five seconds after you have finished pumping before removing the fill nozzle. Clean fuel from painted surfaces as soon as possible. See Exterior Care 0 411. Reinstall the cap by turning it clockwise until it clicks.

Warning

If a fire starts while you are refueling, do not remove the fill nozzle. Shut off the flow of fuel by shutting off the pump or by notifying the station attendant. Leave the area immediately.

Caution

If a new fuel cap is needed, get the right type of cap from your dealer. The wrong type of fuel cap may not fit properly, may turn on the malfunction indicator lamp, and could damage the fuel system and emissions system. See Malfunction Indicator Lamp (Check Engine Light) 114.

Filling a Portable Fuel Container

Warning

Never fill a portable fuel container while it is in the vehicle. Static electricity discharge from the container can ignite the fuel vapor. You or others could be badly burned and the vehicle could be damaged. To help avoid injury to you and others:

• Dispense fuel only into approved containers.
• Do not fill a container while it is inside a vehicle, in a vehicle’s trunk, in a pickup bed, or on any surface other than the ground.
• Bring the fill nozzle in contact with the inside of the fill opening before operating the nozzle. Maintain contact until filling is complete.
• Keep sparks, flames, and smoking materials away from fuel.
• Avoid using electronic devices while pumping fuel.
• When transporting a fuel container or other material that can catch fire in the truck bed, secure the container to prevent spills.
