adding 2cycle oil to rx 8 gas for performance and wear protection

I head that adding oil to the gas in our rx8s not only is good for the engine ,but in increases performance as well http://www.racingbeat.com/Tech/Tech.Oil.2.htm

Hmmm.... Interesting, but I guess not too surprising given the nature of the Renesis/rotary engine design. I wouldn't have thought of it though.
For those of you not patient enough to search the page, here is what dug is referring to....

While undertaking development work on the RX-8 Renesis engine for SCCA T2/T3 use, we decided to introduce extra oil into the fuel to monitor the effect. To our surprise, this additional oil increased power! Further dyno testing found that by adding 10 oz. of Royal Purple 2-Stroke Oil to 6 gallons of fuel, we gained an average of 1.7 HP from 2000-9000 RPM, along with an increase in peak power of 4 HP. We validated this increase by changing back to a “non-oiled” fuel - and the power returned to the previous level. Later, we tried the same test with another brand of synthetic oil with nearly the same results.

For racing applications, the addition of a high quality synthetic oil increases power and most certainly decreases wear. The only negatives are the cost of the oil and an increase in the tendency to foul the spark plugs. (Note: We have not performed these tests on non-RX-8 engines yet, these results are unknown.)

Nice find, Dug!! Thanks for posting it.

One cup of diesel fuel per 5 gallons of gas will do the same thing. Also works on normally aspirated engines.

NA, as in piston engines or Rotary's?
If that's what you are referring to, I would be concerned about the catalytic converter getting clogged, or failing prematurely due to all that burned carbon entering it.
