Get Fuel -> Gasoline additives Guide for Volkswagen Passat SUV Sixth Generation (2005-2010)

ꢀ

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 criteria 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 performance problems.

Damage to the engine and fuel system and performance problems caused by using fuels

ꢀ

that are different from those specified above or by using “starting assist fluids” are not the

responsibility of Volkswagen and are not covered under the Emission 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.

Applicable only in the United States and Canada

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.

Diesel fuel

ꢀPlease first read and note the introductory information and heed the WARNINGS

Always use only Ultra Low Sulfur Diesel (ULSD) fuel No. 2 ⇒ꢀ

The ULSD must always meet ASTM D-975 specification ⇒ꢀ

“ULSD” should be clearly marked on the pump. Before filling your vehicle, please always make sure

you are using ULSD. According to Federal regulations ULSD is the only diesel fuel type allowed for

use in your vehicle.

Using diesel fuel with concentrations of methyl ester biodiesel higher than 5% (B5), such as B11, B20,

or B100 when B5 biodiesel is available, is contrary to the terms of your New Vehicle Limited Warranty

and is strictly prohibited.

ULSD diesel fuel may not be available outside the USA and Canada. Be sure to check availability

before traveling to other countries.

Winter diesel

At temperatures below 20 °F (-7 °C), wax separation in ULSD occurs. Wax may clog the fuel filter or

tank filter and keep the engine from running.

To help prevent the filter from being clogged with wax, the fuel filter in your vehicle is heated with

warm fuel when the engine is running (filter preheating system). Heating the fuel filter makes it

possible to use your vehicle with ULSD down to about -10 °F (-24 °C).

If you expect temperatures below +5 °F (-15 °C) ask your fuel dealer if their ULSD is sufficiently

winterized.

If non-winterized or insufficiently winterized diesel fuel has already thickened to the point that the

engine will not start, move the vehicle to a heated garage or workshop until it has warmed up.

Cold diesel engines normally produce louder noises during winter conditions than during warmer

periods. In addition, the exhaust gases may be light blue in color until the engine has warmed up. The

exhaust gas volume varies depending on the outside temperature.

Do not let your diesel engine idle unnecessarily after a cold start. Driving off slowly will shorten the

warm-up period.

Illinois registered vehicles

Biodiesel is a domestically produced, clean-burning and renewable partial substitute for conventional

(petroleum) diesel fuel.

Your vehicle was originally designed to run on “ULSD” – Ultra Low Sulfur Diesel fuel [ASTM D-975

standard Grade No. 2-D (S15)] that complies with ASTM D-975 specifications and permits up to a

maximum blend of 5 % biodiesel (B5).

Due to Illinois state tax incentives or regulations for biofuels, biodiesel blends of B5 or less may not be

available in Illinois. However, we want to assure you that Volkswagen will continue to honor the terms
