APPLICATIONS
- Does not
comply with the FIM regulation (but
complies to some National Regulations
referring to fuels like "AVGAS 100LL").
- Especially
blended for 2-stroke engines generally
running at moderate revolution speeds
(generally lower than 12 000 rpm),
but having high compression ratios
(like CROSS engine).
- ELF SPECIAL
CROSS has been specifically blended
to match as well as possible the
typical operating conditions of
CROSS or ENDURO races. Furthermore,
its high octane numbers leads to
excellent protection against pinking.
- Compared
to a classic AVGAS 100 LL or other
similar conventional fuel, power
improvements from 5 to 10% have
been observed. Even more important
benefits have also been reported
in transient conditions (pick up
and accelerations).
RECOMMENDATIONS
- Best results
are obtained for CO emission levels
from the tail pipe in the range
of 4 to 6%. An optimum protection
against wear and tightening risks
will be obtained by the association
of this fuel with our HTX 976 special
lubricant (recommended percentage
: 2 to 3%).
- Apart from
cross engines, we recommend ELF
SPECIAL CROSS for all 2-stroke engines
which do not require a fuel with
very high octane numbers and with
a max engine speed relatively limited.
Excellent results have been obtained
with 2 stroke IN BORD, JET SKI,
...
- In order
to maintain the original properties,
and according to Health and Safety
regulations of commercial fuels,
this gasoline must be handled and
stored in a cool place and always
maintained in tightly shut drums.
- Thanks to
its high octane potential and its
chemical composition, this fuel
may be used for 4-stroke engines
having high cylinder pressure operations,
like "dragsters".
