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 car, 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 car’s
fuel, cooling, or lubricating systems. Overuse may damage your engine,
and some of these additives contain organically volatile chemicals. Do
not needlessly expose yourself to these chemicals.
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 requirements
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.
