After my last flight for the year, I stored my plane above the rafters in my non-heated garage and didn't get it back down for 5 years in Ohio. I left 1/2 tank of fuel in and also left the batteries in the plane. I didn't cover nothing up!

After 5 years I got it down, charged the batteries, blew on the carburator to get any dust out, filled it up with fuel and flew it for 2 more years before I sold it.

In fact, up until this year I have never used any type of after run oil in my engines and never had a problem with any of them. Why I started using it now, I'll never know! Makes me feel better I guess and that's about it! Well, I'm not even to sure about that. With what I paid for the after run oil, I could have had a couple extra props.

But what do I know about anything?
