6 GENERAL INFORMATION
GASOLINE-OIL
Recommended
Gasoline (Carbureted
Models)
The recommended gasoline to use in
these snowmobiles is 87 octane regular
unleaded. In many areas, oxygenates
(either ethanol or MTBE) are added to
the gasoline. Oxygenated gasolines
containing up to 10% ethanol or up to
15% MTBE are acceptable gasolines;
however, whenever using oxygenated
gasolines, the carburetor main jet must
be one size larger than the main jet
required for regular unleaded gasoline.
For example, if a 400 main jet is rec-
ommended for regular unleaded gaso-
line, a 410 main jet must be installed if
using an oxygenated gasoline.
When using ethanol blended gasoline,
it is not necessary to add a gasoline
antifreeze since ethanol will prevent
the accumulation of moisture in the
fuel system.
Recommended
Gasoline (EFI Models)
The recommended gasoline to use in
these snowmobiles is 87 octane regular
unleaded.

NOTE: On the 2-stroke EFI
engine models for optimum perfor-
mance, do not exceed the recom-
mended 87 octane gasoline. Using
a higher octane gasoline will not
increase overall performance.

NOTE: The Z1 Turbo models will
detect lower octane gasoline and
reduced engine performance will
result. It is recommended that 91
octane (minimum) gasoline be
used in these models.
In many areas, oxygenates (either etha-
nol or MTBE) are added to the gaso-
line.
Oxygenated gasolines containing up to
10% ethanol or up to 15% MTBE are
acceptable gasoline. Do not use gaso-
lines containing methanol.
Recommended
Injection Oil
The recommended oil to use in the oil-
injection system is Arctic Cat 50:1
Injection Oil (for standard models) or
Arctic Cat Synthetic APV 2-Cycle Oil
(for APV models). These oils are spe-
cially formulated to be used either as
an injection oil or as a pre-mix oil (for
break-in) and meets all of the lubrica-
tion requirements of the Arctic Cat
snowmobile engine.
Recommended Engine
Oil (1100 cc Models)
The recommended oil to use is Syn-
thetic Turbo 0W-40 Oil (p/n 5639-
173).
! CAUTION
Do not use white gas or gasolines
containing methanol. Only Arctic
Cat approved gasoline additives
should be used.
! CAUTION
Do not use white gas or gasoline
containing methanol. Only Arctic
Cat approved gasoline additives
should be used.
! CAUTION
Any oil used in place of the recom-
mended oil could cause serious
engine damage.
