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 condition.  
Never use starting assist fluids.  
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 high 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  
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.
