Snowmobile 

Identification

The Arctic Cat Snowmobile has two important identifica-

tion numbers. The Vehicle Identification Number (VIN)

is stamped into the tunnel near the right-side footrest. The

Engine Serial Number (ESN) is stamped into the crank-

case of the engine.

0726-383

These numbers are required to complete warranty claims

properly. No warranty will be allowed by Arctic Cat Inc.

if the engine serial number or VIN is removed or muti-

lated in any way.

Recommended 

Gasoline and Oil

RECOMMENDED GASOLINE 

(Carbureted Models)

The recommended gasoline to use in these snowmo-

biles is 87 minimum 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 gaso-

lines; 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 recommended for regular

unleaded gasoline, 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 minimum octane regular unleaded, and the Fuel

Designation Connector at the ECU must be connected. 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, if oxygenated gasoline is used, the

Fuel Designation Connector at the ECU must be discon-

nected. Do not use gasolines containing methanol.

734-482A

„

NOTE: In order for the ECU to change modes, the

engine must be OFF when connecting or discon-
necting the Fuel Designation Connector. 

RECOMMENDED OIL

(Oil-Injection System)

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).

The oil is specially formulated to be used either as an

injection oil or as a pre-mix oil (for carbureted model

break-in) and meets all of the lubrication requirements of

the Arctic Cat snowmobile engine.

! 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

If oxygenated gasoline is to be used, it is
extremely important that the Fuel Designation
Connector at the ECU is disconnected. If the
connector is not disconnected when using
oxygenated gasoline, severe engine damage
may occur.
