blockage, with subsequent performance impairment
and possible malfunction.
Gasoline and alcohol
Petrol and alcohol are not fuels for diesel engines.
Petrol (gasoline) and alcohol raise the octane rating
and lower the cetane rating (ignition properties). In
addition, the lubricity is considerably impaired. The
components in the fuel system can be damaged by
petrol (gasoline) and alcohol. In addition, petrol
(gasoline) and alcohol lower the flash point, which
affects the explosion limit and fire safety. Because of
the lower boiling point, the risk of vapour lock in the
system is increased since the fuel can boil in the
cylinder head etc.
Diesel boosters
Many manufacturers of commercially available
additives (so called diesel boosters) promise reduced
fuel consumption and improved lubricity, although
they do not have any demonstrable effect whatsoever
on either fuel consumption or lubricity.
Volvo does not accept any responsibility for warranty
claims if these additives have been used and it is not
Volvo's policy to test or evaluate these additives.
FAME
FAME (Fatty Acid Methyl Esters), also called
"biodiesel" are available on certain markets both as in
its pure state and as a mixture in diesel fuel. FAME is
also known as e.g. rapeseed methyl ester (RME) and
sunflower/Soya methyl ester (SME). When mixed in
normal diesel fuel, the concentration of FAME is
maximum 5%, in accordance with EN590.
Raw vegetable oil or animal oils do not fulfil
EN14214 and shall not be used as a fuel or a
mixture component for diesel engines. These
products are not approved by Volvo and the use of
unapproved products voids the guarantee.
When using FAME:
Caution!
Petrol (gasoline) and alcohol
must never be mixed with diesel
fuel!
Note!
It is not permissible to add diesel
boosters to the fuel.
