2013 VOLKSWAGEN GOLF GTI fuel additives

Fuel
Introduction
In this section you’ll find information about:
Gasoline
Gasoline additives
The correct fuel grade for your engine is shown on a sticker located on the inside of the fuel filler flap
⇒ fig. 147.
Bad or poor quality fuel reduces operating performance, efficiency and service life of the engine. If you
notice any symptoms like rough engine idle or performance or “bucking,” immediately reduce the
vehicle speed, accelerate slowly, and keep the engine speed in the middle of the rpm range. Avoid
high rpm and rapid acceleration. If these symptoms should appear right after refueling, switch off the
engine. In both cases contact an authorized Volkswagen dealer or an authorized Volkswagen Service
Facility to have the engine checked.

WARNING
Improper refueling or handling of fuel is dangerous and can cause fire, explosion, and severe
burns.
x Fuel is highly explosive and flammable and can cause severe burns and other injuries.
x Heed applicable safety warnings and obey local fuel handling regulations.
x Always make sure the fuel cap is screwed on all the way. This keeps fuel from spilling out
and from evaporating.
x Failure to shut the engine off while refueling and/or to insert the pump nozzle fully into the
vehicle's filler neck could cause fuel overflow and fuel spray. Fuel spray and overflowing fuel
are dangerous because they can cause fire or serious injury.
x For safety reasons, the engine must be turned off when refueling.
x Never get back into your vehicle while refueling. If in exceptional circumstances you must
get back in your vehicle while refueling, make certain that you close the door and touch metal
to discharge static electricity before touching the filler nozzle again. Static electricity can
cause sparks that can ignite fuel vapors released during refueling.
Gasoline additives

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.
x Using incorrect gasoline additives can cause extensive engine damage as well as damage
to the catalytic converter.
x 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.
x 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.
x 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.

Engine oil quality is based not only on requirements for engines and exhaust treatment systems, but
also on fuel quality. Engine oil comes into contact with fuel and fuel residue in all internal combustion
engines, causing engine oil to age and its lubricating qualities to deteriorate.
Your engine was factory-filled with a high-quality, “synthetic” all-season engine oil that meets strict
Volkswagen oil quality standards and has a viscosity grade of SAE 5W-40. or SAE 5W-30. You can
use this oil for normal driving in all temperatures.
If you need to add oil between oil changes, use only a high quality oil that expressly complies with the
Volkswagen oil quality standard specified for your vehicle's engine:

Engines Engine oil specification
Gasoline engines
VW 502 00
VW 503 00
VW 504 00

At the time this Manual was printed, the engine oils available in the U.S. that meet these Volkswagen
standards are “synthetic” oils. This does not mean, however, that any “synthetic” engine oil will meet
Volkswagen standards. Always use an approved oil that expressly complies with the Volkswagen oil
quality standard that applies to your vehicle's engine.
General recommendations:
If “synthetic” oil that meets the applicable Volkswagen oil quality standard with viscosity grade
SAE 5W-40 or SAE 5W-30 is not available in your area, be sure to use a viscosity grade suitable for
the climate, season, and operating conditions that exist where the vehicle is used. Make sure the oil
meets the quality standard listed in
Engine oils are constantly being improved. Authorized Volkswagen dealers and authorized
Volkswagen Service Facilities are always up-to-date regarding new developments and changes.
Volkswagen therefore recommends that you have the engine oil changed by an authorized
Volkswagen dealer or an authorized Volkswagen Service Facility.
NOTICE
x If you need to add oil and there is none available that meets the Volkswagen oil quality
standard your engine requires, you may add a total of no more than 1/2 quart (0.5 liter) of a
high-quality “synthetic” oil that meets ACEA A3 specifications and has a viscosity grade of
SAE SAE 5W-40 or SAE 5W-30.
x Use only a high quality engine oil that expressly complies with the Volkswagen oil quality
standard specified for your vehicle's engine. Using any other oil can cause serious engine
damage that will not be covered by any Volkswagen Limited Warranty.
x Do not mix any lubricants or other additives into the engine oil. Doing so can cause engine
damage! Damage caused by these kinds of additives are not covered by any Volkswagen
Limited Warranty.
