Canyon 4WD L5-3.5L VIN 6 (2004)
Fuel: Specifications
GASOLINE OCTANE
Use regular unleaded gasoline with a posted octane of 87 or higher. If the octane is less than 87, you may get a heavy knocking noise when you drive.
If this occurs, use a gasoline rated at 87 octane or higher as soon as possible. Otherwise, you might damage your engine. A little pinging noise when
you accelerate or drive uphill is considered normal. This does not indicate a problem exists or that a higher-octane fuel is necessary. If you are using
87 octane or higher-octane fuel and hear heavy knocking, your engine needs service.
GASOLINE SPECIFICATIONS
It is recommended that gasoline meet specifications which were developed by automobile manufacturers around the world and contained in the
World-Wide Fuel Charter which is available from the Alliance of Automobile Manufacturers at www.autoalliance.org/fuel_charter.htm. Gasoline
meeting these specifications could provide improved driveability and emission control system performance compared to other gasoline.
In Canada, look for the "Auto Makers' Choice" label on the pump.
CALIFORNIA FUEL
If your vehicle is certified to meet California Emission Standards (see the underhood emission control label), it is designed to operate on fuels that
meet California specifications. If this fuel is not available in states adopting California emissions standards, your vehicle will operate satisfactorily on
fuels meeting federal specifications, but emission control system performance may be affected. The malfunction indicator lamp may turn on (see
Malfunction Indicator Lamp ) and your vehicle may fail a smog-check test. If this occurs, return to your authorized GM dealer for diagnosis. If it is
determined that the condition is caused by the type of fuel used, repairs may not be covered by your warranty.
ADDITIVES
To provide cleaner air, all gasoline in the United States are now required to contain additives that will help prevent engine and fuel system deposits
from forming, allowing your emission control system to work properly. You should not have to add anything to your fuel. However, some gasoline
contain only the minimum amount of additive required to meet U.S. Environmental Protection Agency regulations. General Motors recommends that
you buy gasoline that are advertised to help keep fuel injectors and intake valves clean. If your vehicle experiences problems due to dirty injectors or
valves, try a different brand of gasoline.
Gasoline containing oxygenates, such as ethers and ethanol, and reformulated gasoline may be available in your area to contribute to clean air. General
Motors recommends that you use these gasoline, particularly if they comply with the specifications described earlier.
NOTICE: Your vehicle was not designed for fuel that contains methanol. Do not use fuel containing methanol. It can corrode metal parts in your fuel
system and also damage the plastic and rubber parts. That damage would not be covered under your warranty.
Some gasoline that are not reformulated for low emissions may contain an octane-enhancing additive called methylcyclopentadienyl manganese
tricarbonyl (MMT); ask the attendant where you buy gasoline whether the fuel contains MMT. General Motors does not recommend the use of such
gasoline Fuels containing MMT can reduce the life of spark plugs and the performance of the emission control system may be affected. The
malfunction indicator lamp may turn on. If this occurs, return to your authorized GM dealer for service.
FUELS IN FOREIGN COUNTRIES
If you plan on driving in another country outside the United States or Canada, the proper fuel may be hard to find. Never use leaded gasoline or any
other fuel not recommended in the previous text on fuel. Costly repairs caused by use of improper fuel would not be covered by your warranty.
To check the fuel availability, ask an auto club, or contact a major oil company that does business in the country where you will be driving.
