2008 VOLVO S60 fuel additives

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 vehicle during this period. See page 193
.
Fuel requirements
Deposit control gasoline (detergent additives)
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 drivability and fuel
economy. If you are not sure whether the gasoline contains deposit control additives, check with the service station
operator.
NOTE
Volvo does not recommend the use of external fuel injector cleaning systems.
Unleaded fuel
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 labelled "UNLEADED". Only these pumps have nozzles which fit
your vehicle's filler inlet. It is unlawful to dispense leaded fuel into a vehicle labelled "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 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 a trained and qualified Volvo service technician for service.
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.

General information
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 requirements
Octane ratingMINIMUM
Volvo recommends premium for best performance, but using 87 octane or above will not affect engine reliability.
Volvo engines are designed to achieve rated horsepower, torque, and fuel economy performance using premium 91
octane fuel.RECOMMENDED
In demanding driving conditions, such as operating the vehicle in hot weather, towing a trailer, or driving for extended
periods at higher altitudes than normal, it may be advisable to switch to higher octane fuel (91 or higher) or to change
gasoline brands to fully utilize your engine's capacity, and for the smoothest possible operation.
NOTE
When switching to higher octane fuel or changing gasoline brands, it may be necessary to fill the tank more than
once before a difference in engine operation is noticeable.
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
ProCarManuals.com

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 vehicle'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.

Refueling
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 a trained and qualified Volvo service technician for correction.
WARNING
Driving with the trunk open: Driving with the trunk open could lead to poisonous exhaust gases entering the
passenger compartment.
If the trunk must be kept open for any reason, proceed as follows:
Close the windows
Set the ventilation system control to air flow to floor, windshield and side windows and blower control to its
highest setting.
Fuel filler door
Press the button on the light switch panel (see illustration on page 57) when the vehicle is at a standstill to unlock the
fuel filler door. Please note that the fuel filler door will remain unlocked until the vehicle begins to move forward. An
audible click will be heard when the fuel filler door relocks.
If you intend to leave your vehicle while it is being refueled, this feature enables you to lock the doors/trunk while

Oil additives must not be used.
NOTE
Synthetic oil is not used when the oil is changed at the normal maintenance services. This oil is only used at customer
request, at additional charge. Please consult a trained and qualified Volvo service technician.
Oil viscosity (stable ambient temperatures)
Operation in hot climates
When temperatures exceed 104° F (40° C) in your area, Volvo recommends, for the protection of your engine, that you
use a heavier weight oil, such as such as SAE 5W -40 or 0W -40. See the viscosity chart.
Operation in temperate climates
Incorrect viscosity oil can shorten engine life. Under normal use when temperatures do not exceed 104° F (40° C), SAE
5W -30 will provide good fuel economy and engine protection. See the viscosity chart.
Extreme engine operation
Synthetic oils meeting SAE 0W -30 or 0W -40 and complying with oil quality requirements are recommended for driving
in areas of sustained temperature extremes (hot or cold), when towing a trailer over long distances, and for prolonged
driving in mountainous areas.
193 09 Maintenance and servicing
Engine oil
American Petroleum Institute (API) symbol
The API Service Symbol "donut" is divided into three parts:
ProCarManuals.com

The upper section describes the oil's performance level.
The center identifies the oil's viscosity.
The lower section indicates whether the oil has demonstrated energy-conserving properties in a standard test in
comparison to a reference oil.
NOTE
Volvo uses different systems to indicate a low oil level or pressure. Some models have an oil pressure sensor, in which
case a warning symbol (see page 50
) is used to indicate low oil pressure. Other models have an oil level sensor, in
which case the driver is alerted by the warning symbol in the center of the instrument panel and a text in the information
display. Some models use both systems. Contact a trained and qualified Volvo service technician for more information.
Changing engine oil and oil filter
See the previous page for oil specifications and page 246
for oil volumes. Refer to the Warranty and Service Records
Information booklet for information on the oil change intervals.
NOTE
Volvo does not recommend the use of oil additives.
Synthetic oil is not used when the oil is changed at the normal maintenance intervals except at owner request and at
additional charge. Please consult a trained and qualified Volvo service technician.
Checking and adding oil
The oil level should be checked every time the vehicle is refueled. This is especially important during the period up to the
first scheduled maintenance service.
The vehicle should be parked on a level surface when the oil is checked.
If the engine is warm , wait for at least 10- 15 minutes after the engine has been switched off before checking the oil.
Checking the oil
1. Pull out the dipstick and wipe it with a lint-free rag.
2. Reinsert the dipstick, pull it out, and check the oil level.
3. Add oil if necessary. If the level is close to the MIN mark, add approximately 1 US quart (1 liter) of oil.
4. Run the engine until it reaches normal operating temperature.
5. Switch off the engine and wait for at least 10-15 minutes and recheck the oil level. If necessary, add oil until the level
is near the mark.
