Stick 40

I know there has been a lot of back and forth on this after run oil thing.

I think I got dirt in my .46 evo and removed the back plate to flush it with water. The back of the crank and bearings showed rust stain. I kind of got lazy on the after run at the end of a flying day. There were so many saying , they did not use it.

But it is a used engine, I got it with a plane. I don't know what the other guy did.

I plan to go back to using after run oil ( marvel that is ), the cost is almost nothing.
