Deposit control (detergent) gasoline  
Volvo recommends the use of detergent gasoline to control engine deposits. Detergent  gasoline is effective in keeping
injectors  and  intake  valves clean. Consistent use of deposit control gasolines will help ensure good driveability and
fuel economy. If you are not sure whether the gasoline contains deposit control additives, check with the service
station operator.
Unleaded fuel  
ProCarManuals.com 
Each Volvo has a  three-way catalytic converter and  must  use only unleaded gasoline. U.S. and  Canadian regulations
require that pumps delivering unleaded gasoline be  labeled "UNLEADED".  Only these pumps have nozzles which  fit
your car's filler  inlet. It is unlawful to dispense  leaded fuel into a  vehicle labeled "unleaded gasoline only". Leaded
gasoline damages the three-way 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.
NOTE: Some U.S. and  Canadian gasolines contain  an  octane enhancing additive called methly-cyclopentadienyl
manganese  tricarbonyl (MMT). If such fuels  are used, your Emission Control System  performance may be  affected,
and  the Check Engine Lamp located on your instrument panel may light. If this  occurs, please return your vehicle to
an  authorized Volvo retailer for service.
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 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
wear  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.
ENGINE  OIL  
Although some oil consumption occurs during normal engine operation, more oil is consumed when the engine is new
as the internal parts  generate  higher friction  while wearing in to each other. From the time the engine is new until
the first service  is performed, the oil consumption  could be higher than  normal. For this reason, it is especially
important to check  the oil every time you refuel your car during this period. See  page 114

Octane rating  
Volvo engines are designed for optimum performance on unleaded premium gasoline with an  octane rating. AKI of 91,
or above. AKI (ANTI KNOCK INDEX)  is an  average of the Research Octane Number, RON, and  the Motor Octane
Number, MON. (RON  +  MON/2).  
The minimum octane requirement is AKI 87 (RON  91).
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
