G'day to all.
I have been using an Australian oil for after run and engine lay-up. It is called INOX
http://www.inox-mx3.com/
One thing about this oil though is that often when I flip the prop to distribute the oil it will fire-up and run in a decent burst. This is a pain (as my bitten fingers attest) and so I relube but turn the engine over carefully and slowly. This even happens with glow engines, which as you know, have a much lower compression ratio than a diesel.
I suspect that INOX is a vegetable oil as it is non-toxic and used by the food industry. As I cannot afford to sacrifice engines as guinea pigs to science I do not intend to investigate this personally - but I though that this may be of interest in the quest for etherless fuels.
