Volvo 1990 780 Model
Leaded gasoline damages the catalytic converter 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.
Octane Rating
Volvo recommends the use of premium unleaded gasoline with an (R+M)/2 octane rating, also called the
Anti-Knock Index or AKI, of 91 or higher. This is generally equivalent to a Research Octane Number
(RON) of 95 or higher.
Minimum: AKI 87 equivalent to RON 91.
Gasoline Containing Alcohol
Some fuel suppliers sell gasoline containing alcohols without advertising the presence of alcohol. If you
are not sure whether there is alcohol or ethers in the gasoline you buy, check with the service station
operator.
Blends of unleaded gasoline and ethanol (ethyl alcohol, grain alcohol), sometimes called "gasohol", are
available in some areas. Gasohol, if used, must contain no more than 10 percent ethanol and must have
an (R+M)/2 rating of 87 or higher. If you experience problems with starting, driveability, or fuel
economy with gasohol, you should discontinue its use.
Take care not to spill gasoline during refueling. Gasolines containing alcohol can cause damage to
painted surfaces, which may not be covered under the New Vehicle Warranty. Do not use gasolines
containing methanol (methyl alcohol, wood alcohol). This practice can result in vehicle performance
deterioration and can damage critical parts in the fuel system. Such damage may not be covered under
the NEW VEHICLE LIMITED WARRANTY.
