Gasoline containing alcohol and ethers

"Oxygenated fuels"
Some fuel suppliers sell gasoline containing "oxygenates" which are usually alcohols or ethers. In some
areas, state or local laws require that the service pump be marked indicating use of alcohols or ethers.
However, there are areas in which the pumps are unmarked. If you are not sure whether there is alcohol
or ethers in the gasoline you buy, check with the service station operator. To meet seasonal air quality
standards, some areas require the use of "oxygenated" fuel.
Volvo allows the use of the following "oxygenated" fuels; however, the octane ratings listed on this page
must still be met.
Alcohol - Ethanol: Fuels containing up to 10% ethanol by volume may be used. Ethanol may also be
referred to as Ethyl alcohol, or "Gasohol".
Ethers - MTBE: Fuels containing up to 15% MTBE may be used.

Carbon Monoxide - Important Warning

Carbon monoxide is a poisonous, colorless, and odorless gas. It is present in all exhaust gases. If you
ever smell exhaust fumes inside the vehicle, make sure the passenger compartment is ventilated, and
immediately return the vehicle to your retailer for correction.

Fuel Formulations

Do not use gasoline that contains lead as a knock inhibitor, and do not use lead additives. Besides
damaging the exhaust emission control systems on your vehicle, lead has been strongly linked to certain
forms of cancer.
Many fuels contain benzene as a solvent. Unburned benzene has been strongly linked to certain forms of
cancer. If you live in an area where you must fill your own gas tank, take precautions. These may
include:
standing upwind away from the filler nozzle while refueling
refueling only at gas stations with vapor recovery systems that fully seal the mouth of the filler neck
during refueling
wearing neoprene gloves while handling a fuel filler nozzle.

Use of Additives

With the exception of gas line antifreeze during winter months, do not add solvents, thickeners, or other
store-bought additives to your vehicle's fuel, cooling, or lubricating systems. Overuse may damage your
