thanks for the feedback, guys.
and to further confirm that its fine with technical data, i just found this chart below that shows SAE 40 grade oil actually has lower viscosity at 20 deg C than 10W40 grade oil at 10 deg C.
since the malaysian climate is between 22-32 deg C and 10w40 oil is designed to work in temps as low as -30 deg C, i can safely say that monograde SAE 40 is perfectly fine to use in malaysia.
I'll probably stick to using monograde for my iswara coz its cheaper and works great.

sae40 has HIGHER viscosity I.e. more resistance than 10W40 at 10°C.and to further confirm that its fine with technical data, i just found this chart below that shows SAE 40 grade oil actually has lower viscosity at 20 deg C than 10W40 grade oil at 10 deg C.

and yes, if petronas sell it here, u can be sure it suits our local use. basically we don't need multigrade but it is cheaper to sell it than to create a monograde oil series
