WHICH OIL IS BEST FOR THE MAZDA RX7 FD ROTARY WANKEL ENGINE 

I always had the urge for a Mazda Rx7, timeless classic with a quirky Rotary engine, who some say is very unreliable. I love a challenge, love the sexy shape of the FD3S Rx7, and this one came up for the right price, but with a long list of jobs that would need doing, some of them which could have cost thousands to repair! We wouldn't be Mod or Fix if we didn't buy it, so here goes.. :)
The car came to me with the wrong oil in the engine, so this had to be addressed pronto!
