Using diesel fuel with concentrations of methyl ester biodiesel higher than 20 % (B20), such as B100
is still contrary to the terms of your Emission warranties or any other Volkswagen Limited Warranty
and remains strictly prohibited.
Biodiesel blends (up to B20) may be used in your Illinois registered TDI
®
Clean Diesel vehicle;
however, please be aware that biodiesel has characteristics that are different from other kinds of fuel,
especially petroleum-based fuels.
Biodiesel can attract water and also deteriorate with age. Small amounts of biodiesel can get into the
engine oil, but unlike petroleum diesel, it does not evaporate over time. This can cause the oil level in
the engine to rise and can affect the quality of the oil.
x
Routinely check the engine oil level. A good time to do this is when you refuel, especially if you
regularly do a lot of short distance or stop-and-go driving. This will help you see if the engine oil level
is getting higher. (A rising oil level beyond the maximum indicator means an oil change is needed due
to the dilution of the oil in the system; a potential characteristic of biodiesel use)

If you ever notice that the engine oil level has risen or is above the maximum indicator, contact
your authorized Volkswagen dealer, authorized Volkswagen Service Facility or Volkswagen Customer
CARE to schedule an oil change – regardless of the time or mileage that has elapsed since you last
had an oil change performed.
x
Continue to follow the oil change intervals found in the Warranty and Maintenance booklet that
came with your vehicle, and use only engine oil that expressly complies with Volkswagen quality
standard VW 507 00.
x
Refuel only at trusted, commercial fueling stations that are located near main highways. These
stations are more likely to have “fresh” biodiesel fuels that have not aged significantly.
x
If your vehicle will be in storage (or not driven) for several weeks or months, please completely fill
the fuel tank. If possible, fill the tank with Ultra Low Sulfur Diesel fuel [ASTM D-975 standard Grade
No. 2-D (S15)].

NOTICE
x
The vehicle's diesel engine was designed solely for use with ULSD fuel. For this reason,
never use gasoline, heating oil, or other fuels that have not been expressly approved for use
with the diesel engine. These fuels contain substances that will severely damage the fuel
system and the engine. Such damage will not be covered by any Volkswagen Limited Warranty.
x
If you put any amount of the incorrect fuel in the fuel tank, do not start the engine under any
circumstances. Immediately contact the nearest authorized Volkswagen dealer or authorized
Volkswagen Service Facility for assistance.
x
If diesel fuel should get on any rubber hose, it must be wiped off immediately. The same
applies if diesel fuel gets onto other parts of the vehicle, especially paint, tires, or a plastic
part. Wash the contaminated vehicle parts right away with soap and warm water to help
prevent leaks and serious damage.
