Hi,

Using after run oil is not permitted with YS engines. Except from burning any remaining fuel after operating what else must be done before storing a YS engine for a long period of time?

Rgrds,

If you don't desire to use after run oil, just run it dry, remove it from the airplane, and store it in a place with small temperature extremes, like inside your house.

We sell an after run oil which is compatible with YS engines. It is called Ultra Oil and you can buy it online at www.pspec.com

Good Flying!
