The factory recomends only non synthetic oil for RX 7's and 8's.
It is possible to run synthetic after a sufficient break in period but the oils should be changed at regular intervals. It is my belief that heavier oil should be run in the summer months or during periods of hard driving. I recomend 20-50.

Who are you, and what credentials do you have to recommend oils that are counter to the Mazda warrantee requirements?
