fuel additives VOLKSWAGEN CC 2012 Owners Manual

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 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. Never use fuel line antifreeze offered for
gasoline engines.
Gasoline additives

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.
