Gasoline Containing Alcohol And Ethers; Fuel Formulations - Volvo S40 2005 Owner's Manual

2005 Volvo S40
and the heated oxygen sensor system. Repeated use of leaded gasoline will lessen the effectiveness of
the emission control system and could result in loss of emission warranty coverage. State and local
vehicle inspection programs will make detection of misfueling easier, possibly resulting in emission test
failure for misfueled vehicles.
NOTE: Some U.S. and Canadian gasolines contain an octane enhancing additive called methyl-
cyclopentadienyl manganese tricarbonyl (MMT). If such fuels are used, your Emission Control System
performance may be affected, and the Check Engine Light (malfunction indicator lamp) located on your
instrument panel may light. If this occurs, please return your vehicle to an authorized Volvo retailer for
maintenance.

Gasoline containing alcohol and ethers

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.

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
pg. 102 Fuel requirements
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.
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.
