I use one of my three 4 strokes engines all the time, that one doesn't get any after run oil, the other two I use them not so often those two get the after run oil at the end of the day.
What I'm trying to prevent here by using the ARO is corrosion on the bearings.
I have been maintaining these engines like that for about 6 years now and they are running strong.
