[m400] synthetic oil

The m400 series is a newly developed product based on the concept of being an all-purpose gear oil that can be used from transmissions with relatively rough clearances to transmissions with compact designs in recent years, and has a design with slightly higher cushioning properties than the m408..
this oil is exclusively for manual transmissions, with a carefully considered blending balance of multiple hydrocarbon-based synthetic base oils and multiple ester-based synthetic base oils from the ground up, and a new design from the selection of functional additives to the balance.the 75w140 grade functional additive has a different composition intended for use in lsd.
