RE: After Run Oil And Omega Fuel ( Morgan )
I recently discovered something very interesting. I purchasd an OS 90 four stroke brand new in the mid 80's. I bench ran it to break it in a few times. Then a few more for kicks. I was a kid, so I wasn't really into caring for the engines very much. The engine sat around after that in the garage, in the house, various places as it was moved through the years. It was in very humid areas, consequently, the outside had some corrosion, the bolts on the outside also had rust. I recently took the engine apart after all these years, and was blown away to find absolutely no rust on the inside! The bearings had varnish on them from the gumming of the fuel and oil left in it, but the cylinder wall, the ring, the piston, the valves, literally looked like new!! I was quite surprised. Leaves me to believe that whatever these fuel manufacturers put in their fuel for rust prevention works very good. I did never put any type of oil in the engine after I ran it whatsoever.
