I wonder if the oil injection system in the RX -8 cars was/is injecting
too much oil.  I'm running my Renesis with Shon's alternate oil adapter
and his manual oil metering adjuster.  At max. oil  setting I used 2 oz.
oil while burning less than 1/2 gal. of fuel.  Oil was being spit out of
the intake past the throttle body!  I now have the oil injection rate
set at about 1/4 inch from the minimum oil injection rate.  It probably
is close to 3/4 oz. oil/ gal.  This is the same amount of oil Tracy is
mixing with the fuel.  I'm not flying - still ground running the engine
while working on the cowl and inlet system.

For all out racing with shifting above 9,600 RPM, I use one ounce per gallon. It sounds like you could do with quite a bit less than you are using now.
