It was a PITA indeed. I started scrubbing with avgas soaked rags and finished with acetone. Also tried a steelwool-like something don't remember now.

Happy New Year!

Are you saying you use 2 cases (24 quarts) of oil every 100hrs? :confused:

My recommendation would be Aeroshell 50 weight Mineral Oil until the engine is broke in. My engine change intervals on Lycomings are first oil change at 5 hours and then 25 hours thereafter. After the engine is broke in I switch to Aeroshell W100.

Yes on average. I recycle about 5 quarts during the change the rest is consumed by the engine.
