Hello everyone,

I have the RE4FO4W but have seen this classified as RE4FO4V on AMSOIL and other product websites when I have entered my car info when searching for a full synthetic ATF, but assuming this is the same VLSD , or am I wrong?

Also, knowing that the difference between the 1998 Infiniti I30 and Touring is the Viscous Limited slip differential. I am surprised to see that the two share the same ATF classification of Matic D or Dextron III. I would assume some form of additive would have been necessary due to more moving , but also extend the life of the compared to a non-VLSD due to more pressure and requirement for higher viscosity to be functional.
