I've been using the VI in all my automatics since shortly after it came out (none of them Corvairs). It's synthetic and supposedly much better. Napa usually makes me a pretty good deal when I buy 10 cases at a time. My Malibu's old metric 200 has been gradually working better as the fluid keeps getting changed. It used to slip in reverse but quit after about 3 changes. Any type of fluid may have done the same.
