octane VOLKSWAGEN CC 2009 Owners Manual

d For gasoline engines: Is unleaded fuel with the right octane rating
readily available?
d Are engine oil (⇒ Engine oil) and other operating fluids that meet
Volkswagen quality and performance requirements available where
you will be driving? For more information, please see
⇒ Booklet Warranty and Maintenance.
d Does the factory-installed navigation system work in the countries
where you will be driving, and is navigation data available?
d Are special or heavy-duty tires necessary for the kind of driving
expected?

Volkswagen is not responsible for mechanical damage that may
result from substandard fuel or service or the unavailability of

TOP TIER Detergent Gasoline, please go to the official Web site,

The gasoline grades most commonly sold in the United States and
Canada have the following octane ratings, which can usually be found
on the filler pump:
Premium grade: 91 to 96 AKI
Regular grade: 87 to 90 AKI
Unleaded gasoline
Unleaded gasoline is available throughout the USA and Canada.
Volkswagen recommends that you do not take your vehicle to places
where unleaded gasoline may not be available.
Gasoline containing alcohol or MTBE
You may use unleaded gasoline blended with alcohol or MTBE (me-
thyl tertiary butyl ether), commonly referred to as oxygenated fuels, if
the blended mixture meets the following criteria:
Blends of gasoline and methanol (wood alcohol or methyl alco-
hol):
Anti-Knock Index (AKI) must be 87 or higher.
Blend must contain no more than 3% methanol.
Blend must contain more than 2% co-solvents.
Blends of gasoline and ethanol (grain alcohol or ethyl alcohol):
Anti-Knock Index (AKI) must be 87 or higher.
Blend must contain no more than 15% ethanol.
Blends of gasoline and MTBE:
Anti-Knock Index (AKI) must be 87 or higher.
Blend must contain no more than 15% MTBE.
Seasonally adjusted gasoline
Many fuels are blended especially for winter or summer conditions.
When seasons change, Volkswagen suggests that you buy fuel at
busy stations where the seasonal adjustment is more likely to be
made earlier.

WARNING
Starting fluids can explode and cause a run-away vehicle condi-
tion.
Never use starting assist fluids.
NOTICE
Never use fuel with an octane rating lower than 87 AKI /
91 RON. Using lower octane fuel may cause expensive engine
damage.
Never use leaded gasoline! Leaded gasoline will severely
damage your vehicle's catalytic converter.
Methanol-blended fuels that do not meet the criteria listed
above may cause corrosion and may damage plastic and rubber
parts in the fuel system.
Never use fuels that contain lead or other metals (check listing
on the fuel pump). Even lead replacement gasoline (LRP fuels)
contain metallic additives in high concentrations. They can
damage the engine.
Do not use fuels that fail to meet the criteria above, or with
contents that cannot be identified.
If you cannot tell whether a particular fuel blend meets the cri-
teria above, ask your service station or its fuel supplier. If you
notice a loss of fuel economy or drivability and performance
problems using one of these fuel blends, we recommend that
you switch to unblended fuel.
Using fuels that are different from those specified above can
damage your vehicle's engine and fuel system and cause per-
formance problems.
Damage to the engine and fuel system and performance prob-
lems caused by using fuels that are different from those speci-
fied above or by using “starting assist fluids” are not the re-
sponsibility of Volkswagen and are not covered under the Emis-
sion warranties or any other Volkswagen Limited Warranty.
Even a single tank full of leaded fuel can do major damage to the
catalytic converter and degrade its effectiveness in reducing polluting
emissions.

If you must fuel your vehicle with gasoline whose octane rat-
ing is too low, only drive with the engine speed in the middle of
the rpm range and with low engine load. Avoid high rpm and
heavy engine load. Otherwise, the engine could be damaged.
Refuel your vehicle with gasoline with the required octane rating
as soon as possible.
Do not use fuel that is labeled at the pump as containing met-
al. Lead replacement fuel contains high concentrations of metal-
lic additives. Engine damage could result.
Fueling your vehicle just one time with leaded fuel or fuel that
contains other metallic additives can affect the performance of
the catalytic converter and cause extensive damage to it.

Government regulations in the United States and Canada require that
automobiles meet specific emission regulations and safety standards.
Therefore, vehicles built for the U.S. and Canada differ from vehicles
sold in other countries.
If you plan to take your vehicle outside the continental limits of the
United States or Canada, there is the possibility that:
Unleaded fuels for vehicles with catalytic converters may not be
available.
Fuel may have a considerably lower octane rating and may cause
engine damage.
Service may be inadequate due to lack of proper service facilities,
tools or testing equipment.
Replacement parts may not be readily available.
DVD navigation systems for vehicles built for the United States and
Canada will not necessarily work in Europe, and may not work in oth-
er countries outside of North America.
NOTICE
Volkswagen is not responsible for mechanical damage that may
result from substandard fuel or service or the unavailability of
Genuine Volkswagen parts.
Volkswagen is not responsible if the vehicle does not meet the
respective legal requirements in other countries and continents.
