What kind of oil should be used?
I was reading online, and it said that synthetic oil shouldn't be used in a rotary motor.
But then other people say that certain types of synthetic oil is okay, and in some cases, better to be used.
Sorry, I'm learning, but I don't know this and so I figured I would ask, and maybe someone would be able to help me.
Thanks,
Shaina

Name-brand mineral motor oils are perfectly fine.
Synths just cost more and give you miniscule gains in power and gas mileage.
If you feel like paying 3x the cost for oil changes just to gain the 1-2hp increase, then it's your money.
Synths do have the reputation of "causing" more oil leaks, so old vehicles like ours can start to leak like a sieve...be prepared.

Yay, another oil topic. Ignoring the obvious advice of checking the owners manual, factory service manual, FAQ or the chart under the hood, a simple search would have turned up all this information.
Here's a search for "oil type":

That's in the first two pages. I ran another search for "recommended oil" and got all this:

And I stopped after page three.
Just for the record, the Factory Service Manual can be found in the FAQ For FC thread. It contains all this information and more, and is an essential tool for any sort of service work that needs to be performed on these cars.
Additionally, the Haynes service manual for the 1986 thru 1991 RX-7 (both turbo and NA) can be found at most local auto parts stores or purchased from any good bookstore (ISBN number 1 56392 007 7). It is only about $25 and is a great quick reference for things like this. Not only does it contain most of the information in the FSM condensed into an easy to read format, but it includes full wiring diagrams as well.
These manuals will answer 99% of service related questions for the car and if you intend to do your own repair work, you will need at least one of them. Preferably both, since the FSM is a free download.
Now, closing thread.
