2018 Alfa Romeo Stelvio Owner's Manual

FUEL REQUIREMENTS
This engine is designed
to meet all emission
regulations, and
provide satisfactory
fuel economy and
performance when
using high-quality
unleaded “Regular”
gasoline having a posted octane number
of 87 as specified by the (R+M)/
2 method. For optimal performance the
use of 91 or higher octane “Premium”
gasoline is recommended in these
engines.
While operating on gasoline with the
required octane number, hearing a light
knocking sound from the engine is not a
cause for concern. However, if the engine
is heard making a heavy knocking sound,
see your authorized dealer immediately.
Use of gasoline with a lower than
recommended octane number can cause
engine failure and may void or not be
covered by the New Vehicle Limited
Warranty.
Poor quality gasoline can cause problems
such as hard starting, stalling, and
hesitations. If you experience these
symptoms, try another brand of gasoline
before considering service for the
vehicle.
Reformulated Gasoline
Many areas of the country require the
use of cleaner burning gasoline referred
to as “Reformulated Gasoline”.
Reformulated gasoline contains
oxygenates and are specifically blended
to reduce vehicle emissions and improve
air quality.
The use of reformulated gasoline is
recommended. Properly blended
reformulated gasoline will provide
improved performance and durability of
engine and fuel system components.
Gasoline/Oxygenate Blends
Some fuel suppliers blend unleaded
gasoline with oxygenates such as
ethanol.
Caution!
DO NOT use E-85, gasoline containing
methanol, or gasoline containing more than
15% ethanol (E-15). Use of these blends
may result in starting and drivability
problems, damage critical fuel system
components, cause emissions to exceed the
applicable standard, and/or cause the
“Malfunction Indicator Light” to illuminate.
Please observe pump labels as they should
clearly communicate if a fuel contains
greater than 15% ethanol (E-15).
Problems that result from using gasoline
containing more than 15% ethanol (E-15)
or gasoline containing methanol are not the responsibility of the manufacturer
and may void or not be covered under
New Vehicle Limited Warranty.
CNG And LP Fuel System Modifications
Modifications that allow the engine to
run on compressed natural gas (CNG) or
liquid propane (LP) may result in damage
to the engine, emissions, and fuel system
components. Problems that result from
running CNG or LP are not the
responsibility of the manufacturer and
may void or not be covered under the
New Vehicle Limited Warranty.
MMT In Gasoline
Methylcyclopentadienyl Manganese
Tricarbonyl (MMT) is a manganese-
containing metallic additive that is
blended into some gasoline to increase
octane. Gasoline blended with MMT
provides no performance advantage
beyond gasoline of the same octane
number without MMT. Gasoline blended
with MMT reduces spark plug life and
reduces emissions system performance
in some vehicles. The manufacturer
recommends that gasoline without MMT
be used in your vehicle. The MMT content
of gasoline may not be indicated on the
gasoline pump; therefore, you should ask
your gasoline retailer whether the
gasoline contains MMT. MMT is
prohibited in Federal and California
reformulated gasoline.
255

Materials Added To Fuel
Besides using unleaded gasoline with the
proper octane rating, gasolines that
contain detergents, corrosion and
stability additives are recommended.
Using gasolines that have these additives
will help improve fuel economy, reduce
emissions, and maintain vehicle
performance.Designated TOP TIER
Detergent Gasoline
contains a higher level
of detergents to
further aide in
minimizing engine and
fuel system deposits.
When available, the usage of TOP TIER
Detergent gasoline is recommended.
Visit www.toptiergas.com for a list of
TOP TIER Detergent Gasoline Retailers.
Indiscriminate use of fuel system
cleaning agents should be avoided. Many
of these materials intended for gum and
varnish removal may contain active
solvents or similar ingredients. These can
harm fuel system gasket and diaphragm
materials.
Fuel System Cautions
Caution!
Follow these guidelines to maintain your
vehicle’s performance:
The use of leaded gasoline is prohibited
by Federal law. Using leaded gasoline can
impair engine performance and damage the
emissions control system.
An out-of-tune engine or certain fuel or
ignition malfunctions can cause the
catalytic converter to overheat. If you
notice a pungent burning odor or some light
smoke, your engine may be out of tune or
malfunctioning and may require immediate
service. Contact an authorized dealer for
service assistance.
The use of fuel additives, which are now
being sold as octane enhancers, is not
recommended. Most of these products
contain high concentrations of methanol.
Fuel system damage or vehicle
performance problems resulting from the
use of such fuels or additives is not the
responsibility of the manufacturer and may
void or not be covered under the New
Vehicle Limited Warranty.
Note: Intentional tampering with the
emissions control system can result in
civil penalties being assessed against
you.

SUGGESTIONS FOR OBTAINING
SERVICE FOR YOUR VEHICLE
Prepare For The Appointment
If you are having warranty work done, be
sure to bring the right papers with you, as
well as your warranty folder. All work to
be performed may not be covered by the
warranty. Discuss additional charges with
the service manager. Keep a maintenance
log of your vehicle's service history, as
this can often provide a clue to the
current problem.
Prepare A List
Make a written list of your vehicle's
problems or the specific work you want
done. If you've had an accident or work
done that is not on your maintenance log,
let the service advisor know.
Be Reasonable With Requests
If you list a number of items and you must
have your vehicle by the end of the day,
discuss the situation with the service
advisor and list the items in order of
priority. At many authorized dealers, you
may obtain a rental vehicle at a minimal
daily charge. If you need a rental, it is
advisable to make these arrangements
when you call for an appointment.
IF YOU NEED ASSISTANCE
The manufacturer and its authorized
dealer are vitally interested in your
satisfaction. We want you to be happy
with our products and services.
Warranty service must be done by an
authorized dealer. We strongly
recommend that you take the vehicle to

service. The manufacturer's authorized
dealer have the facilities, factory-trained
technicians, special tools, and the latest
information to ensure the vehicle is fixed
correctly and in a timely manner.
This is why you should always talk to an
authorized dealer service manager first.
Most matters can be resolved with this
process.
If for some reason you are still not
satisfied, talk to the general manager or
owner of the authorized dealer. They
want to know if you need assistance.
If an authorized dealer is unable to
resolve the concern, you may contact the
manufacturer's customer center. Any communication to the
manufacturer's customer center should
include the following information:
