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 perfor-
mance requirements for motorcy-
cle and ATV clutches and
transmissions.
There are two classes, MA and
MB. The oil container shows the
classification as follows.

Energy Conserving
Suzuki does not recommend the
use of “ENERGY CONSERVING”
oils. Some engine oils which have
an API classification of SH or
higher have an “ENERGY CON-
SERVING” indication in the API
classification doughnut mark.
These oils can affect engine life
and clutch performance.
