Gurgle for oil level check

Prop slowly. Let the gases blow by the pistons and push the oil out and up.

I have also discovered that my Sting Sport gurgles quicker with fresh, clean oil than with old, dirty oil. I have thus shifted to 30-35 hour oil changes. Also, if I prop it while warm after use, it gurgles quicker the next morning while cold. Cold air temps; dirty, thick oil; lack of gurgle, whilst warm after the previous run; can make for 45-150 prop turns on my airplae. Sometimes, I got NO gurgle at all, no matter how many props.

Now, with clean oil, warmer summer air temps, and pre-gurgling (at last use), I consistently hear that lovely sound, mostly after just 4-14 turns of a prop blade!

I am finding that I can turn the prop over and over up to 100 times and still not get a gurgle when the motor is cold. Now, I run the engine until I get 120deg oil temp. Shut down. Turn the prop normal to quick and now can get a gurgle on about number 15-20. Strange. :ohmy:
