Is it possible that with older rotary engines the internal oils

my old engine, even though I still have the oil injection

I started mixing two stroke oil with the gas in addition to
the oil injection.  Just as insurance, and it's easy anyway,
since I usually fill up with two 5-gallon cans from the
gas station.  I just add about 8-10 oz. by volume (cut-off
water bottle) per 5 gallon can of gas. Is this about right?

I think my fuel-sight gauges don't like the oil in the gas,
getting some strange crazing.

That's too much oil Perry.   1 oz per gallon (without any oil injection) is
enough.  Don't laugh, but when I use any more than this, I have to DRAIN
excess oil from the crankcase after about 30 hours of flight.  The oil
recovery rings are scraping the excess oil from the sidewalls and putting it
in the crankcase.
