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.
pg. 65 Refueling
Refueling
The fuel tank is designed to hold approximately 21.1 US gal. (80 liters) with sufficient volume left over
to accommodate possible expansion of the fuel in hot weather. Be aware that the "usable" tank capacity
will be somewhat less than the specified maximum. When the fuel level is low, such factors as ambient
temperature, the fuel's "Reid vapor pressure" characteristics, and terrain can affect the fuel pumps'
ability to supply the engine with an adequate supply of fuel. Therefore, it is advisable to refuel as soon
as possible when the needle nears the red zone, or when the fuel warning light comes on.
