here we go again. i think Michael Yount runs Amsoil in his Z spec. probably a wise choce, but i have no first hand knowledge on that (in my stock WC T5, i run redline D4).
good luck with the new trans.
whoa, dont go based on what i said. i dont know if there is anything special about the Z in terms of oiling needs (or if it is just different ratios and ratings, etc). i think the guts are about the same, but check with someone who knows or runs one.....but im 99% sure you are good to go with the same stuff WC t5's take. just double check.
amsoil comes from mail order mostly - maybe a speed shop in your area might have some.....
