fuel additives VOLVO C70 CONVERTIBLE 2007 Owner´s Manual

2007 Volvo C70
In demanding driving conditions, such as operating the vehicle in hot we\
ather, towing a trailer, or driving
for extended periods at higher altitudes than normal, it may be advisabl\
e to switch to higher octane fuel
(91 or higher) or to change gasoline brands to fully utilize your engi\
ne'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.
Deposit control gasoline (detergent additives)
Volvo recommends the use of detergent gasoline to control engine deposit\
s. Detergent gasoline is
effective in keeping injectors and intake valves clean. Consistent use o\
f deposit control gasolines will help
ensure good drivability and fuel economy. If you are not sure whether th\
e gasoline contains deposit
control additives, check with the service station operator.
NOTE
Volvo does not recommend the use of store-bought fuel injector cleaning \
additives.
Unleaded fuel
Each Volvo has a three-way catalytic converter and must use only unleade\
d 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 t\
hree-way catalytic converter and
the heated oxygen sensor system. Repeated use of leaded gasoline will le\
ssen the effectiveness of the

emission control system and could result in loss of emission warranty co\
verage. State and local vehicle
inspection programs will make detection of misfueling easier, possibly r\
esulting in emission test failure
for misfueled vehicles.
NOTE
Some U.S. and Canadian gasolines contain an octane enhancing additive ca\
lled methyl-
cyclopentadienyl manganese tricarbonyl (MMT). If such fuels are used, \
your Emission Control System
performance may be affected, and the Check Engine Light (malfunction in\
dicator lamp) located on your
instrument panel may light. If this occurs, please return your vehicle t\
o an authorized Volvo retailer for
maintenance.
Gasoline containing alcohol and ethers
Some fuel suppliers sell gasoline containing "oxygenates" which are usua\
lly alcohols or ethers. In some
areas, state or local laws require that the service pump be marked indic\
ating 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 al\
so be referred to as Ethyl
alcohol, or "Gasohol". Ethers - MTBE: Fuels containing up to 15% MTBE ma\
y be used.
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 benze\
ne 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:
l standing upwind away from the filler nozzle while refueling
l refueling only at gas stations with vapor recovery systems that fully se\
al the mouth of the filler neck
during refueling

l wearing neoprene gloves while handling a fuel filler nozzle.
WARNING
Carbon monoxide is a poisonous, colorless, and odorless gas. It is prese\
nt in all exhaust gases. If you
ever smell exhaust fumes inside the vehicle, make sure the passenger com\
partment is ventilated, and
immediately return the vehicle to your retailer for correction.
Use of Additives
With the exception of fuel line antifreeze during winter months, do not \
add solvents, thickeners, or other
store-bought additives to your vehicle's fuel, cooling, or lubricating s\
ystems. Overuse may damage your
engine, and some of these additives contain organically volatile chemica\
ls. Do not needlessly expose
yourself to these chemicals.
Fuel filler door
Press the button on the light switch panel (see the illustration on
page 55) with the ignition switched off
to unlock the fuel filler door. Please note that the fuel filler door wi\
ll remain unlocked until the vehicle
begins to move forward. An audible click will be heard when the fuel fil\
ler door relocks.

Fuel requirements
If you intend to leave your vehicle while it is being refueled, this fea\
ture enables you to lock the doors/
trunk while leaving the fuel filler door unlocked.
You can also keep the vehicle locked if you remain inside it during refu\
eling. The central locking button
does not lock the fuel filler door.
Be sure the fuel filler door is not obstructed and is completely closed \
after refueling. Open the fuel filler
cap slowly during hot weather.
Refueling
The fuel tank is designed to hold approximately 15.9 US gallons (60 lit\
ers)1 with sufficient volume left
over to accommodate possible expansion of the fuel in hot weather. Be aw\
are 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, a\
nd terrain can affect the fuel

NOTE
Volvo does not recommend the use of oil additives.
l Synthetic oil is not used when the oil is changed at the normal maintena\
nce intervals except at owner
request and at additional charge. Please consult your Volvo retailer.
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
l The car should be parked on a level surface when the oil is checked.
l 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 appr\
oximately 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 MAX mark.

Depending on your driving habits, premium or synthetic oils may provide \
superior fuel economy and engine
protection. Consult your Volvo retailer for recommendations on premium o\
r synthetic oils.
Oil additives must not be used.
NOTE
Synthetic oil is not used when the oil is changed at the normal service \
intervals. This oil is only used at customer
request, at additional charge. Please consult your Volvo retailer.
Oil viscosity (stable ambient temperatures)
Operation in hot climates
When temperatures exceed 86° F (30° C) in your area, Volvo recom\
mends, for the protection of your engine, that
you use a heavier weight oil, such as such as SAE 5W-40 or 0W-40. See th\
e viscosity chart.
Operation in temperate climates
Incorrect viscosity oil can shorten engine life. Under normal use when t\
emperatures do not exceed 86° F (30° 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
