Engine oil

oil.

formance and life.
Always select good quality engine oil.
Use oil with an API classification of SG, SH, SJ, SL,
SM or SN with a JASO classification of MA.
JASO T903
The JASO T903 standard is an index to select engine
oils for 4-stroke motorcycle and ATV engines.
Motorcycle and ATV engines lubricate clutch and
transmission gears with engine oil.
JASO T903 specifies performance requirements for
motorcycle and ATV clutches and transmission.
There are two classes, MA and MB.
The oil container shows the classification as shown.
A: Code number of oil sales company

Energy Conserving
Suzuki does not recommend the use of "ENERGY
CONSERVING" or "RESOURCE CONSERVING" oils.
Some engine oils which have an API classification of
SH, SJ, SL, SM or SN have an "ENERGY CONSERV-
ING" or "RESOURCE CONSERVING" indication in the
API classification donut mark.
These oils can affect engine life and clutch perform-
ance.
