Fuel/Gasoline information

Warning

Never swallow fuel. Fuels such as gasoline, bioethanol, and mixtures of these are very toxic and can cause permanent injury or even death if they are swallowed. Seek medical attention immediately if you have swallowed fuel.

Always take precautions to avoid inhaling gasoline fumes or getting gasoline splashed in your eyes.

If you get gasoline in your eyes, remove contact lenses if applicable, rinse your eyes thoroughly with water for at least 15 minutes and seek medical attention.

Carbon monoxide is a toxic, colorless and odorless gas. It is present in all exhaust gases. If you ever notice the smell of exhaust inside the vehicle, make sure the passenger compartment is ventilated and contact an authorized Volvo workshop for any required repairs or servicing.

Avoid any fires, such as from cigarette lighters and lit cigarettes.

When refueling your vehicle, always follow your local restrictions.

Important

Refueling your vehicle

Only use gasoline from well-known manufacturers. Never refuel your vehicle if you aren't sure about the fuel's quality.

Always use the correct gasoline. Look at the label on the inside of the fuel filler flap. Even small amounts of the wrong type of fuel could damage the fuel system and engine.

Always follow the warning signs posted at the gas station.

Close all doors and windows before you start refueling.

Additives and quality

To avoid damage to the engine, only use unleaded gasoline.

U.S. and Canadian regulations require pumps delivering unleaded gasoline to be labeled UNLEADED. Repeated use of gasoline with lead additives reduces the efficiency of the emissions control systems and may result in the invalidation of the emissions warranty.

Do not use fuel containing methanol.

Except for the use of antifreeze for fuel lines during the winter, do not use solvents, thickeners or other additives in the vehicle's fuel, cooling or lubrication systems. Overuse may damage your engine, and some of these additives contain volatile organic compounds. Do not needlessly expose yourself to these chemicals.

Some suppliers use gasoline with additives. If you are unsure whether the gasoline contains deposit-controlling additives, ask at the fueling station.

Emission controls

Important

Three-way catalytic converter

• Keep your engine properly tuned. Certain engine malfunctions, particularly involving the electrical, fuel or distributor ignition systems, may cause unusually high three-way catalytic converter temperatures. Do not continue to operate your vehicle if you notice engine misfire, noticeable loss of power or other unusual operating conditions, such as engine overheating or backfiring. A properly tuned engine will help avoid malfunctions that could damage the three-way catalytic converter.
• Do not park your vehicle on top of combustible materials, such as grass or leaves. These materials can come into contact with the hot exhaust system and cause such materials to ignite under certain wind and weather conditions.
• Excessive starter cranking, for more than one minute, or an intermittently firing or flooded engine, can cause three-way catalytic converter or exhaust system overheating.
• Remember that tampering or unauthorized modifications to the engine, the Engine Control Module, or the vehicle may be illegal and could cause three-way catalytic converter or exhaust system overheating. This includes altering fuel injection settings or components, removing or altering emission system components and their location, and repeated use of leaded fuel.

Note

Unleaded fuel

Unleaded fuel is required for vehicles with three-way catalytic converters.

Heated oxygen sensors

Heated oxygen sensors measure the oxygen content of the exhaust gases. The readings help your vehicle monitor engine functions and control fuel injection. To help reduce harmful emissions, the ratio of fuel to air injected into the engine is continuously adjusted for efficient combustion.

The heated oxygen sensors monitor the oxygen content of the exhaust gases. Readings are fed into a control module that continuously monitors engine functions and controls fuel injection. The ratio of fuel to air into the engine is continuously adjusted for efficient combustion to help reduce harmful emissions.

Octane rating

Gasoline has different octane ratings that are suitable for different types of driving.

Volvo requires premium fuel, with an octane rating of 91 or higher according to AKI^[1] for all B4, B5, B6 and T8 engines, and it recommends AKI 93 for ideal performance and fuel economy. In demanding driving conditions, such as warm climates, driving with a trailer or driving for long periods at a higher altitude than normal, it's recommended to change to fuel with a higher octane rating.

If you change to fuel with a higher octane rating or another brand of gasoline, you may have to fill the tank more than once before you notice any difference in engine function.

Note

TOP TIER Detergent Gasoline

Volvo recommends the use of TOP TIER detergent gasoline where available, to maintain engine performance and reliability. Information on TOP TIER detergent gasoline is available at toptiergas.com.
