Crude.
Just playin. It should have stuff like that under the hood, I think.
Otherwise just a tad over 6Q of your favorite 10w30 and an OEM filter. If you're strapped, get a really good filter, not a cheapo Fram. Do not use synthetic.

And why not use synthetic??
From the FAQ's:
As you can see, it is the cheap synthetic that you should not use, good synthetic is fine and used by mazda racing.
I personally use AMSoil synthetic.
From the FAQ's:
Can I use synthetic oils in my Rotary engined car?
Yes and no. Mazda officially does not recommend the use of synthetic oils in rotary engines, however, long term and racing use has shown that the better synthetics (Redline, Amsoil, Neo, Royal Purple, Mobil1) are perfectly fine to use in a rotary engine, and will generally result in a 1 to 2% horsepower gain. However use of poor quality synthetics (like Valvoline, Castrol Syntec, Havoline, Etc) will result in build up due to high ash content left from these oils when they are burned. It is believed that is why Mazda did not recommend synthetics, because the couldn't pick favorites.
Other notes:
The Mazda Factory racing departments recommend and use ‘synthetic’ oils including the winning 1991 Leman’s 20-G 4 rotor Mazda 787B.
MazdaComp USA printed manual (now Mazdaspeed) recommends the use of synthetic oils for racing conditions.
Redline, Amsoil and Royal Purple Synthetic Motor Oils have been used in rotary engines (both race and street) for ten plus years with excellent results.
Most Synthetic Motor Oil is compatible with the bearing material, sealing elastomer's, and combustion seals used in a rotary engine.

Free workshop manuals are available for download in the FAQ section:
https://www.rx7club.com/2nd-generation-specific-1986-1992-17/frequently-asked-questions-2nd-generation-rx-7-faq-fc-494667/
Although 20W-50 is the best-protecting oil for warm regions, see the manual for the correct oil weight for the temperatures in your region. I recommend Castrol GTX non-synthetic oil for the engine, and any brand of synthetic oil (Red Line, Royal Purple, Amsoil, etc.) in the manual transmission and differential. Strangely, the Mazda brand oil filter is generally considered superior to the aftermarket brands.
In order to protect against leaks, you are supposed to replace the gasket when you remove the engine oil drain plug. I really like the aftermarket Fumoto drain valve (F-106 Regular Valve) which never needs to be replaced:
https://www.rx7club.com/general-rotary-tech-support-11/new-gasket-every-oil-change-23575/
Because it is a waste of money to use synthetic oil in the engine of a street car. However, that may change if the price of crude oil keeps going up, lol.

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.
