Gasoline additives

Please first read and note the introductory information and heed the WARNINGS
Additives are used to improve the quality of the gasoline.
Fuel quality impacts the operating performance, efficiency and service life of the engine. Therefore,
use quality gasoline that is already blended by the fuel supplier with suitable gasoline additives that do
not contain metal. The additives provide corrosion protection, clean the fuel system, and prevent
deposits on the engine.
Volkswagen recommends TOP TIER Detergent Gasoline. For more information on TOP TIER
Detergent Gasoline, please go to the official Web site http://www.toptiergas.com.
If quality gasoline with additives that do not contain metal is not available or engine malfunctions
occur, you should add the required additives while refueling ⇒
Not all gasoline additives are effective. Using the wrong additives can cause significant and expensive
damage to the engine and the catalytic converter. Never use additives that contain metal. Please note
that metal can be included in some aftermarket gasoline additives that are available to be added to
gasoline during or after refueling to help improve knock resistance or increase the octane rating.
Volkswagen recommends using only additives approved by Volkswagen. Appropriate additives as well
as instructions on how to use them are available from your authorized Volkswagen dealer or
authorized Volkswagen Service Facility. Do not add any other gasoline additives.
NOTICE
You can damage the engine by using incorrect additives.
Using incorrect gasoline additives can cause extensive engine damage as well as damage
to the catalytic converter.
If you must fuel your vehicle with gasoline whose octane rating 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 metal. Lead replacement fuel
contains high concentrations of metallic 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.
