Dave Leonard What happens to this mixture setting in the aircraft fuel tank for extended time periods? Is a 5 minute "wing rock" a preflight requirement:) Thanks, Randy So far, I haven't noticed any problems with the oil trying to settle out. The only time I ever had a problem was when I had an empty tank, then put 15 oz of oil in it and taxied down to the fuel pump (running off the other tank). I filled the tank, and figured that taxing back to the hanger 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 just poured it back in the tank, and kept doing that until I was getting fuel from the sump. I also rolled the plane forward and back a bit to finish mixing it up. Originally, I thought the oil had settled out, but later I realized that it had just never been mixed. The best lesson here was to realize that if the oil does happen to settle out, it will collect at the drain valve, and I'll see it when I sump the tanks during pre-flight.
