You Should Know Better Than That?

Cut Your premium extra down to premium and you should notice a performance increase. You are over lubricating and hence over compressing the engine. The engine is designed to run a maximum of 15% oil, and I prefer 14%. Wild cat Premium Extra is 18%, and Premium is 16%. Much closer to the Manufacturers specks. Try to load your engine down under 5000 revs at the prop. Remember that at this speed it is turning at 10000 internally. The bearings wont take the punishment too long.
