I saw the piece in the engine column of this months Model Aviation and at one point he indicates that !QUOT!after run oil!QUOT! that he had put into the diesel engine before storage caused the engine not to fire. The article indicated that the antioxidant's that prevents rust also prevents diesel fuel from igniting! I recently had my OS 40FP DDD on the bench to do some testing, I mixed up some starter fluid blend and could not get it to do anything except a couple pops, even with a starter (a weak starter, but none the less). I thought it was that I just got some old starter fluid that was low on ether. After reading this I started to wonder. I have used Marvel Air Tool fluid as after run in all my glows, its good stuff.

Has anyone else had a chance to confirmed this? If true, what do we do with the engines that have been treated with ARO?
