Max-Gear 75w90 is a great choice for Differential Gear Oil for customers just looking for road use  that want an oil that is closer to the recommended weight that Mazda suggest. We personally prefer 75w140 and have used this heavier 75w140 for many years now without issue.

Max-Gear 75w90 can also be used in gearboxes as another alternative to Idemitsu Racing MTF/75w90
