Additives - Mercedes-Benz G-Class Operator's Manual

If standard unleaded gasoline is unavailable
and you have to refuel with unleaded gasoline
of a lower grade, observe the following pre-
cautions:
Only fill the fuel tank to half full with regular
R
unleaded gasoline and fill the rest with pre-
mium-grade unleaded gasoline as soon as
possible.
Do not drive at the maximum speed.
R
Avoid sudden acceleration and engine
R
speeds over 3,000 rpm.
You will usually find information about the fuel
grade on the pump. If you cannot find the label
on the pump, ask the staff for assistance.

E10 fuel contains up to 10% bioethanol.
Your vehicle is E10-compatible. You can
refuel your vehicle using E10 fuel.
As a temporary measure, if the recommended
fuel is not available, you may also use regular
unleaded gasoline with an octane rating of
87 AKI/91 RON. This may reduce engine per-
formance and increase fuel consumption. Avoid
driving at full throttle and sudden acceleration.
Never refuel using fuel with a lower AKI.
Information on refueling (
AMG vehicles
!
Only refuel using super-grade unleaded gas-
oline with at least 98 RON/88 MON that con-
forms to European standard EN 228 or an
equivalent specification.
You could otherwise impair engine output or
damage the engine.
!
Premium-grade unleaded gasoline with an
octane rating of 95 RON/85 MON may be
used as a temporary measure if the recom-
mended fuel is not available. This may reduce
engine performance and increase fuel con-
sumption. Do not drive at full throttle.
!
Regular unleaded gasoline with an octane
rating of 91 RON/82.5 MON may also be
used as an emergency measure if the recom-
mended fuel is not available.
Doing so results in noticeably higher fuel con-
sumption, and the engine power output is
noticeably reduced. Avoid driving at full throt-
tle.

If only regular unleaded gasoline with an
octane rating of 91 RON/82.5 MON or lower
is available, you must have the vehicle adap-
ted to this fuel at a qualified specialist work-
shop.

Additives

!
Operating the engine with fuel additives
added later can lead to engine failure. Do not
mix fuel additives with fuel. This does not
include additives for the removal and preven-
tion of residue buildup. gasoline must only be
mixed with additives recommended by
Mercedes-Benz. Comply with the instructions
for use on the product label. More information
about recommended additives can be
obtained from any authorized Mercedes-Benz
Center.
Mercedes-Benz recommends that you use bran-
ded fuels that have additives.
The quality of the fuel available in some coun-
tries may not be sufficient. Residue could build
up in the fuel injection system as a result. In
such cases, and in consultation with an author-
ized Mercedes-Benz Center, the gasoline may
be mixed with the cleaning additive recommen-
ded by Mercedes-Benz. You must observe the
notes and mixing ratios specified on the con-
tainer.
Fuel consumption information

Environmental note
CO (carbon dioxide) is the gas which scien-
2
tists believe to be principally responsible for
global warming (the greenhouse effect). Your
vehicle's CO emissions are directly related to
2
fuel consumption and therefore depend on:
efficient use of the fuel by the engine
R
driving style
R
other non-technical factors, such as envi-
R
ronmental influences, road conditions or
traffic flow
You can minimize your vehicle's CO
sions by driving carefully and having it serv-
iced regularly.
