Thanks,

So far, I=20 haven't noticed any problems with the oil trying to settle = out. The=20 only time I ever had a problem was when I had an empty tank, = then put=20 15 oz of oil in it and taxied down to the fuel pump (running = off the=20 other tank). I filled the tank, and figured that taxing back to = the hanger=20 would be enough to mix it. The next time I sumped the tank as part = of my pre-flight, what I got in the tester was almost straight = oil. I=20 just poured it back in the tank, and kept doing that until I was = getting=20 fuel from the sump. I also rolled the plane forward and back = a bit to=20 finish mixing it up. Originally, I thought the oil had settled = out, but=20 later I realized that it had just never been=20 mixed.

The best=20 lesson here was to realize that if the oil does happen to settle = out, it=20 will collect at the drain valve, and I'll see it when I sump = the tanks=20 during pre-flight.
