redline MT90 should be good for your car, MSP requres 75w90 because of the LSD.

mt90 is lighter weight then the 75w90. One is GL4 the other is GL5.

Red Line MT-90 is an SAE grade 75W-90 gear oil. The GL-4 or GL-5 rating has nothing to do with viscosity. According to the FSM, the MP3, P5 and sedans with M/T should use 75W-90 oil.

GL-5 provides exteme protection. Look it up.

Mazda clearly states in the FSM that either API service GL-4 or GL-5 can be used in the M/T, so the differential properties of either service classification are irrelevant for our cars. It further states that for all-season use, SAE grade 75W-90 is the correct gear box oil.

Case closed.
