Fuel For Petrol Engines; Fuel For Diesel Engines - Chevrolet 2012 Malibu Owner's Manual

8-42 Driving and Operating
Petrols containing oxygenates,
such as ethers and ethanol,
may be available in your area.
However, fuels containing more
than 15% ethanol, such as
E85 (85% ethanol), or more than
15% MTBE (an ether) should not
be used in vehicles that were not
designed for those fuels. See
Recommended Fluids and
Lubricants on page 10‑7 for
more information.
Notice: This vehicle was not
designed for fuel that contains
methanol. Do not use fuel
containing methanol. It can
corrode metal parts in the fuel
system and also damage plastic
and rubber parts. That damage
would not be covered under the
vehicle warranty.
Some petrols can contain an
octane-enhancing additive called
methylcyclopentadienyl manganese
tricarbonyl (MMT); ask the attendant
where you buy petrol whether the
fuel contains MMT. We recommend
against the use of such petrols.
Fuels containing MMT can reduce
spark plug life and affect emission
control system performance. The
malfunction indicator lamp might
turn on. If this occurs, return to
your dealer for service.

Fuel for Petrol Engines

Commercially available high-quality
fuels are suitable. Fuel quality has a
decisive influence on the power
output, driveability and life of the
engine. The additives contained in
the fuel play an important role in this
regard. You should therefore use
only high-quality fuels containing
additives. Petrol with too low an
octane number can cause pinging
and resulting damage. Petrol with a
higher octane number can always
be used. A dispensing pump for
leaded fuel cannot be inserted in the
fuel tank of a vehicle that must be
operated on unleaded fuel only.
Use of petrol with an octane rating
of 95 will ensure economical driving.

Fuel for Diesel Engines

Diesel engines must be operated
only on commercially available
diesel fuel meeting the
specifications of DIN EN 590.
Marine diesel fuel, fuel oils, diesel
fuels, which are entirely or partially
plant based such as rape seed oil or
bio-diesel, Aquazole and similar
diesel-water emulsions must not be
used. The flow and filterability of
diesel fuels are insufficient at low
temperatures, as a result of
crystallised paraffins. Diesel fuels
with improved low-temperature
properties are therefore available
on the market during the winter
months. Make sure that you use
winter fuel before the start of the
cold weather season. Use of diesel
fuels with manufacturer guaranteed
winter properties eliminates the
need for additives.
