2018 FIAT 500C fuel additives

CAUTION!Do not use chemical flushes in your engine oil as the
chemicals can damage your engine. Such damage is not
covered by the New Vehicle Limited Warranty.
Engine Oil Viscosity (SAE Grade) — 1.4L LA Engine
SAE 5W-30 engine oil approved to FCA Material Standard
FPW9.55535-G1 such as Pennzoil, Shell Helix or equivalent
is recommended for all operating temperatures. This en-
gine oil improves low temperature starting and vehicle fuel
economy.
The engine oil filler cap also shows the recommended
engine oil viscosity for your engine. For information on
engine oil filler cap location, refer to “Engine Compart-
ment” in this section.
Lubricants which do not have both the engine oil certifi-
cation mark and the correct SAE viscosity grade number
should not be used. Synthetic Engine Oils
You may use synthetic engine oils provided the recom-
mended oil quality requirements are met, and the recom-
mended maintenance intervals for oil and filter changes are
followed.
Synthetic engine oils which do not have both the engine oil
certification mark and the correct SAE viscosity grade
number should not be used.
Materials Added To Engine Oil
The manufacturer strongly recommends against the addi-
tion of any additives (other than leak detection dyes) to the
engine oil. Engine oil is an engineered product and its
performance may be impaired by supplemental additives.
Disposing Of Used Engine Oil And Oil Filters
Care should be taken in disposing of used engine oil and
oil filters from your vehicle. Used oil and oil filters,
indiscriminately discarded, can present a problem to the
environment. Contact an authorized dealer, service station
or governmental agency for advice on how and where used
oil and oil filters can be safely discarded in your area. 8SERVICING AND MAINTENANCE 239

FUEL REQUIREMENTS
1.4L Engine LA
This engine is designed to meet all emis-
sion regulations, 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 optimum performance and
fuel economy the use of “Premium” 91 octane gasoline or
higher is recommended.
While operating on gasoline with an octane number of 87,
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 dealer immediately. Use
of gasoline with an octane number lower than 87 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 consider-
ing 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 specifi-
cally blended to reduce vehicle emissions and improve air
quality.
The use of reformulated gasoline is recommended. Properly
blended reformulated gasoline will provide improved perfor-
mance and durability of engine and fuel system components.
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 recom-
mended. Visit www.toptiergas.com for a
list of TOP TIER Detergent Gasoline Retailers. 9TECHNICAL SPECIFICATIONS 287

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 compo-
nents. 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. Gaso-
line 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. 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 perfor-
mance 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 metha-
nol. Fuel system damage or vehicle performance
problems resulting from the use of such fuels or
additives is not the responsibility of the manufac-
turer and may void or not be covered under the New
Vehicle Limited Warranty. 9TECHNICAL SPECIFICATIONS 289
